Working with the Filters, Effects, and Layer Styles palettes

Today we will play and compete with the filters, and if time permits the effect group.Each person will be assigned a specific filter, will chose an appropriate picture to work on and will demonstrate to the rest of the class how to use this filter effectively.

You have a limited number of photos to choose from, choose wisely to have your effect show off. Use this page to choose from:

Index page

From any palette, you can choose from a variety of categories to apply to your images. You can also change how the categories are displayed on a palette.
You can combine the different categories of filters, effects, and layer styles to create unique images from a simple photograph. For example, you can create a dramatic look by combining the Outer Glow category from the Layer Styles palette with Neon Nights from the Image Effect category in the Effects palette.

Using filters

Filters let you apply special visual effects to your images, such as mosaic tile, lighting, and three-dimensional effects. You can also use some filters to clean up or retouch your photos.
Filter sets appear in the Filters palette and in the Filter menu. In addition, some third-party filters appear at the bottom of the Filter menu. Keep in mind the following guidelines when choosing a filter:
* Filters affect the active, visible layer or a selected area of the layer.
* You can't use some filters on images in Grayscale mode, or any filters on images in Bitmap or Indexed Color mode.
* The last filter you applied will appear at the top of the Filter menu and can be reapplied with the same filter settings you last used.

Displaying filter options and applying filters
Applying filters to an image--especially to a large image--can be time-consuming. It's quicker to view an example of the filter's effect in the Filters palette instead. Most filters also let you preview their effect on your image in the Filter Options dialog box and the document window. See Choosing a filter for more information about the effects you can expect from a filter.
To save time when testing the effect of various filters, select a small, representative part of your image.
To set filter options and apply a filter:
1. To apply a filter to an entire layer, deselect any selected areas, and then select the layer in the Layers palette.
2. To apply a filter to a portion of a layer, use any selection tool to select an area.
3. Do one of the following:
* Choose a filter from a submenu in the Filter menu. If a filter name is followed by ellipses (...), a Filter Options dialog box appears.
* In the Filters palette, select the filter you want to apply.
4. To set filter options and preview the filter, select Filter Options at the top of the Filters palette. Or, to apply the preset filter settings deselect Filter Options. (Filter Options and preview windows are not available for all filters.)
5. To apply the filter to your image, double-click the filter, drag the filter into the image, or click Apply in the Filters palette.
6. If a dialog box appears, enter values or select options.
To start over, and reset the filter options, press the Alt (Windows) and click Reset in the dialog box.
7. If available, select the Preview option to preview the filter effect in the document window. Use one of the following methods to preview the effect:
* Use the + or - button under the preview window to zoom in or zoom out on the preview.
* Drag in the preview window to center a specific area of the image in the window.
Note: A flashing line beneath the preview size indicates that the preview is being rendered.
8. Click OK to apply the filter.

Using texture and glass surface controls
The Conté Crayon, Glass, Rough Pastels, Texturizer, and Underpainting filters have texturizing options. These options make images appear as if they are painted onto textures such as canvas and brick or viewed through glass blocks.
To use texture and glass surface controls: Do one of the following:
* Choose the filter from the appropriate submenu in the Filter menu.
* Use the Filters palette to apply the desired filter (make sure Filter Options is selected in the Filters palette before you apply the filter).
1. For Texture, choose a texture type or choose Load Texture to specify a Photoshop file.
2. Drag the Scaling slider to enlarge or reduce the effect on the image surface.
3. Drag the Relief slider (if available) to adjust the depth of the texture's surface.
4. For Light Angle (if available), choose the direction of the light source on the image.
5. Select Invert to reverse the surface's light and dark colors.
6. Click OK.

Tips for applying filters
Try the following techniques to create special visual effects with filters.
Feather the filter edges
If you're applying a filter to a selected area, you can soften the edges of the filter effect by feathering the selection before you apply the filter. See About selections for more information on defining a feathered edge.
Apply filters to multiple layers
Apply filters to individual layers or to several layers in succession to build up an effect. You can choose different blending modes in the Layers palette to blend the effect. (See Specifying layer blending modes.) For a filter to affect a layer, the layer must be visible and must contain pixels.
Create textures and backgrounds
By applying filters to solid-color or grayscale images, you can generate a variety of backgrounds and textures. You can then blur these textures if desired. Although some filters (for example, the Glass filter) have little or no visible effect when applied to solid colors, others produce interesting effects. For such colors, you can use Add Noise, Chalk & Charcoal, Clouds, Conté Crayon, Difference Clouds, Glass, Graphic Pen, Halftone Pattern, Mezzotint, Note Paper, Pointillize, Reticulation, Rough Pastels, Sponge, or Underpainting. You can also use any of the filters in the Texture submenu.
Improve image quality and consistency
You can disguise faults, alter or enhance images, or make a series of images look similar by applying the same filter to each.

 

Challenge one: Artistic filters
Choose an Artistic filter to simulate painterly effects on traditional media, and to create unique visual effects. For example, use the Rough Pastels filter to simulate pastels on a painter's canvas, or use Plastic Wrap to give your image a plastic sheen.
_______________Colored Pencil
Redraws an image using colored pencils on a solid background. Retains important edges and gives them a rough crosshatch appearance; the solid background color shows through the smoother areas. You can set the pencil width, stroke pressure, and paper brightness in the filter options.
For a parchment effect, change the background color before applying the Colored Pencil filter to a selected area.
_______________Cutout
Portrays an image as though it is made from roughly cut-out pieces of colored paper. High-contrast images appear as if in silhouette, while colored images are built up from several layers of colored paper. You can set the tonal levels, edge simplicity, and edge fidelity in the filter options.
_______________Dry Brush
Paints an image using a dry brush technique (between oil and watercolor). The filter simplifies an image by reducing its range of colors to areas of common color. You can set the brush size, brush detail, and texture amount in the filter options.
_______________Film Grain
Applies an even, grainy pattern to an image. Adds a smoother, more saturated pattern to the image's lighter areas. This filter is useful for eliminating banding in blends and visually unifying elements from various sources. You can set the grain amount, highlight area range, and intensity level in the filter options.
_______________Fresco
Paints a layer in a coarse style using short, rounded, and hastily applied dabs. You can set the brush size, brush detail, and texture in the filter options.
_______________Neon Glow
Uses the foreground color, background color, and glow color to colorize an image while softening its look. You can set the glow size, glow brightness, and glow color in the filter options. Lower glow size values restrict the glow color to the shadow areas, and higher values move the glow color to the midtones and highlight areas of a layer. To select a glow color, click the Glow Color box, and select a color in the color picker.
_______________Paint Daubs
Makes an image look painted. You can set the brush size, image sharpness, and brush types in the filter options.
_______________Palette Knife
Reduces detail in an image to give the effect of a thinly painted canvas that reveals the texture underneath. You can set the stroke size, stroke detail, and edge softness in the filter options.
_______________Plastic Wrap
Renders a layer as if it is coated in shiny plastic, accentuating the surface detail. You can set the highlight strength, plastic wrap detail, and plastic smoothness in the filter options.
_______________Poster Edges
Reduces the number of colors in an image according to the posterization option you set, finds the edges of the image, and draws black lines on them. Large broad areas of the image receive simple shading while fine dark details are distributed throughout the image. You can set the edge thickness, edge intensity, and posterization in the filter options.
_______________Rough Pastels
Makes an image appear as if it was stroked with colored pastel chalk on a textured background. In areas of bright color, the chalk appears thick with little texture; in darker areas, the chalk appears scraped off to reveal the texture. You can set the stroke length, stroke detail, and texture in the filter options. For more information on setting the Texture options, see Transforming layers, selections, and shapes.
_______________Smudge Stick
Softens an image using short diagonal strokes to smudge or smear the darker areas of the images. Lighter areas become brighter and lose detail. You can set the stroke length, highlight area, and intensity in the filter options.
_______________Sponge
Paints a layer with highly textured areas of contrasting color. You can set the brush size, image definition, and edge smoothness in the filter options.
_______________Underpainting
Paints a layer as if it exists on a textured background. You can set the brush size, texture coverage area, and texture options in the filter options.
_______________Watercolor
Paints an image in a watercolor style, simplifying details in an image by using a medium brush loaded with water and color. Where significant tonal changes occur at edges, the filter saturates colors. You can set the brush detail, shadow intensity, and texture in the filter options.

Challenge two: Blur filters

________________ _+_____________Blur and Blur More
Eliminate noise where significant color transitions occur in an image. Blur filters smooth transitions by averaging the color values of pixels next to the hard edges of defined lines and shaded areas. The Blur More filter produces an effect several times stronger than that of the Blur filter.
________________ _+_____________Gaussian Blur
Quickly blurs a selection by an adjustable amount. Gaussian refers to the bell-shaped curve that Photoshop Elements generates when it applies a weighted average to the pixels. The Gaussian Blur filter adds low-frequency detail and can produce a hazy effect. You can set the blur radius in the filter options to determine how far the filter searches for dissimilar pixels to blur.
________________ _+_____________Motion Blur
Blurs in a particular direction (from -360º to +360º) and at a specific distance (from 1 to 999). The filter's effect is analogous to taking a picture of a moving object with a fixed exposure time. You can set the blur angle, and distance in the filter options.
________________ _+_____________Radial Blur
Simulates the blur of a zooming or rotating camera to produce a soft blur. Drag the Amount slider to control the blur amount. Choose Spin to blur along concentric circular lines, and then specify a degree of rotation; or choose Zoom, to blur along radial lines, as if zooming in or out of the image, and then specify an amount from 1 to 100. Blur quality ranges from Draft for fast but grainy results to Good and Best for smoother results, which are indistinguishable except on a large selection. Specify the origin of the blur by dragging the pattern in the Blur Center box.
______________ _+_____________Smart Blur
Precisely blurs an image. You can specify a radius to determine how far the filter searches for dissimilar pixels to blur, a threshold to determine how different the pixels' values must be before they are eliminated, and a blur quality. You also can set a mode for the entire selection (Normal) or for the edges of color transitions (Edge Only and Overlay Edge). Where significant contrast occurs, Edge Only applies black-and-white edges, and Overlay Edge applies white.


Challenge three: Brush Stroke filters

Like several of the Artistic filters, the Brush Stroke filters give a painterly or fine-arts look using different brush and ink stroke effects. Some of the filters add grain, paint, noise, edge detail, or texture to an image for a pointillist effect.
1.________________Accented Edges
Accentuates the edges of an image. When the edge brightness control is set to a high value, the accents resemble white chalk; when set to a low value, the accents resemble black ink. You can set the edge width, edge brightness, and smoothness in the filter options.
2.________________Angled Strokes
Repaints an image using diagonal strokes. The lighter areas of the image are painted in strokes going in one direction, while the darker areas are painted in strokes going the opposite direction. You can set the stroke direction balance, stroke length, and sharpness in the filter options.
3.________________Crosshatch
Preserves the details and features of the original image while adding texture and roughening the edges of the colored areas in the image with simulated pencil hatching. You can set the stroke length, sharpness, and strength (the number of hatching passes) in the filter options.
4.________________Dark Strokes
Paints dark areas of an image closer to black with short, tight strokes, and paints lighter areas of the layer with long, white strokes. You can set the stroke balance, and black and white intensity levels in the filter options.
5.________________Ink Outlines
Redraws an image with fine narrow lines over the original details, in pen-and-ink style. You can set the stroke length, and dark and light intensity levels in the filter options.
6.________________Spatter
Replicates the effect of a spatter airbrush. You can set the spray radius, and smoothness in the filter options.
7.________________Sprayed Strokes
Repaints a layer using its dominant colors with angled, sprayed strokes of color. You can set the stroke length, spray radius, and stroke direction in the filter options.
8.________________Sumi-e
Redraws a layer with a Japanese style, as if with a wet brush full of black ink on rice paper. The effect is soft blurry edges with rich blacks. You can set stroke width, stroke pressure, and contrast in the filter options.

Distort filters -
9.________________Using the Liquify filter

The Liquify filter makes it easy to manipulate areas of an image as if those areas had been melted. You work with a preview image of the current layer, using special tools to warp, twirl, expand, contract, shift, and reflect areas of the image. You can make subtle changes to retouch an image or drastic distortions to create an artistic effect.


Using the Liquify filter to distort and reconstruct
To use the Liquify filter:
1. Select the layer or area you want to distort.
2. Choose Filter > Distort > Liquify.
Note: If a type layer is selected, you must simplify the layer before applying the Liquify filter. See Simplifying type layers. Alternatively, to distort type without simplifying the type layer, click the Warp Text button in the type tool's option bar.
3. To zoom in or out on the image preview, do one of the following:
* Choose a zoom level from the pop-up menu in the bottom left area of the dialog box.
* Select the zoom tool from the toolbox in the dialog box, and click in the image to zoom in, or Alt-click (Windows) or Option-click (Mac OS) to zoom out. You can also use the zoom tool to drag over an area of the preview you want to magnify.
4. In the Tool Options section, adjust the brush size and pressure of the tools, as needed:
* To change the brush size, drag the pop-up slider, or enter a brush size value from 1 to 600 pixels.
* To change the brush pressure, drag the pop-up slider, or enter a brush pressure value from 1 to 100.
A low brush pressure makes more gradual changes.
* If you're using a stylus tablet, select Stylus Pressure.
5. Use any of the following tools to distort the preview image:
* The warp tool to push pixels forward as you drag.
* The turbulence tool to smoothly scramble pixels and create fire, clouds, waves, and similar effects. To adjust the smoothness, drag the Turbulent Jitter pop-up slider in the Tool Options section, or enter a value between 1 and 100 in the text box. Higher values increase smoothness.
* The twirl clockwise tool to rotate pixels clockwise as you hold down the mouse button or drag.
* The twirl counterclockwise tool to rotate pixels counterclockwise as you hold down the mouse button or drag.
* The pucker tool to move pixels toward the center of the brush area as you hold down the mouse button or drag.
* The bloat tool to move pixels away from the center of the brush area as you hold down the mouse button or drag.
* The shift pixels tool to move pixels perpendicularly to the stroke direction. Drag to move pixels to the left, and Alt-drag (Windows) or Option-drag (Mac OS) to move pixels to the right.
* The reflection tool to copy pixels to the brush area. Drag to reflect the area perpendicular to the direction of the stroke (to the left of or below the stroke). Alt-drag (Windows) or Option-drag (Mac OS) to reflect the area in the direction opposite to that of the stroke (for example, the area above a downward stroke). Use overlapping strokes to create an effect similar to a reflection in water.
* To fully or partially reverse the changes, use the reconstruct tool. See "To restore a preview image to a previous state" in the next set of procedures.
To create the effect of dragging in a straight line between the current point and the previous point that you clicked, Shift-click with the warp, shift pixels, and reflection tools.
6. To apply the changes in the preview image to the actual image, click OK.

10.________________Using the Displace filter

The Displace filter uses an image, called a displacement map, to determine how to distort a selection. For example, using a parabola-shaped displacement map, you can create an image that appears to be printed on a cloth held at its corners.
This filter requires a displacement map file composed of either a flattened image saved in Photoshop format (see Flattening all layers) or an image in Bitmap mode. You can use your own files or the files included in the Photoshop Elements 2 / Plug-Ins / Displacement Maps folder or the Photoshop Elements 2 / Presets / Textures folder.
To use Displace:
1. Choose Filter > Distort > Displace.
2. To define the magnitude of the displacement, enter a value between -999 and 999 in the Horizontal and Vertical Scale text boxes.
When the horizontal and vertical scales are 100%, the greatest displacement is 128 pixels (because middle gray produces no displacement).
3. If the displacement map is not the same size as the selection, select how the map will fit the image:
* To resize the map, select Stretch to Fit.
* To fill the selection by repeating the map in a pattern, select Tile.
4. Select how to fill voids that are created by the filter in the image:
* To fill voids with content from the opposite edge of the image, select Wrap Around.
* To extend the colors of pixels along the image's edge in the direction specified, select Repeat Edge Pixels.
5. Click OK.
6. Select and open the displacement map.
Photoshop Elements applies the map to the image.


11.________________Applying the Pinch filter

The Pinch filter squeezes a selection or layer inward or outward.
To pinch a layer or selection:
1. Select the layer or area you want to pinch.
2. Choose Filter > Distort > Pinch.
3. Drag the slider to the right, into positive values, to pinch a selection inward toward its center; or to the left, into negative values, to shift a selection outward.
4. Click OK.
12.________________Applying the Shear filter

The Shear filter distorts an image along a curve.
To shear a layer or selection:
1. Select the layer or area you want to shear.
2. Choose Filter > Distort > Shear
3. To define a distortion curve, do one of the following in the Shear dialog box:
* Click anywhere on either side of the vertical line.
* Click on the vertical line, and then drag the new curve point.
You can drag any point along the curve to adjust the distortion, and you can add additional curve points.
4. Select one of the following in the Undefined Areas options:
* Wrap Around fills new voids in the image with content from the opposite side of the image.
* Repeat Edge Pixels extends the colors of pixels. Banding may result if the edge pixels are different colors.
You can click Defaults to start over and return the curve to a straight line.

13________________Applying the Spherize filter

The Spherize filter gives objects a 3D effect by wrapping a selection around or inside a spherical shape, distorting and stretching the image.
For more options and control, use the 3D Transform filter. See Using the 3D Transform filter.
To spherize a layer or selection:
1. Select the layer or area you want to spherize.
2. Choose Filter > Distort > Spherize.
3. Drag the slider to the right, into positive values, to stretch the image outward as if it's wrapped around a sphere. Drag the slider to the left, into negative values, to stretch the image inward as if it's wrapped inside a sphere.

14________________Applying the Twirl filter
The Twirl filter rotates a selection more sharply in the center than at the edges. Specifying an angle produces a twirl pattern. Select the layer or area you want to twirl, and then choose Filter > Distort > Twirl.
To apply the Twirl filter:
1. Select the layer or area you want to twirl.
2. Choose Filter > Distort > Twirl.
3. Drag the slider to the right into positive values to twirl the image clockwise, drag to the left into negative values to twirl counterclockwise, or enter a value between -999 and 999.
15________________Applying the Wave filter

The Wave filter creates an undulating pattern on a layer or selection. You can set the wave pattern type, and fine tune various wave properties.
To apply the Wave filter:
1. Select the layer or area you want to undulate.
2. Choose Filter > Distort > Wave.
3. Select a wave type in the Type section: Sine (creates a rolling wave pattern), Triangle, or Square.
4. To set the number of wave generators, drag the slider or enter a number between 1 and 999.
5. Drag the minimum and maximum Wavelength sliders to set the distance from one wave crest to the next. Set both sliders to the same value to create a consistent pattern of wave crests.
6. Drag the minimum and maximum Amplitude sliders to set the wave strength.
7. Drag the horizontal and vertical Scale sliders to set the height and width of the wave effect.
8. To apply random results based on the set of values in the dialog box, click Randomize. You can click Randomize multiple times to get more results.
9. Select the Wrap Around option to fill the voids in the image with content from the opposite edge of the image, or select Repeat Edge Pixels to extend the colors of pixels along the image's edge in the direction specified.
10. Click OK.
16________________Applying the ZigZag filter
The ZigZag filter distorts a selection radially, depending on the radius of the pixels in your selection.
To apply the ZigZag filter:
1. Select the layer or area you want to affect.
2. Choose Filter > Distort > ZigZag.
3. Drag the Amount slider to set the level and direction of distortion.
4. Drag the Ridges slider to set the number of direction reversals for the zigzag from the center of to the edge of the selection.
5. Choose a displacement option from the Style pop-up menu:
* Around Center rotates the pixels around the center of the selection.
* Out From Center produces a rippling effect toward or away from the center of the selection.
* Pond Ripples produces a rippling effect that distorts the selection to the upper left or lower right.
6. Click OK.


Challenge four: Noise filters

The Noise filters add or remove noise, or pixels with randomly distributed color levels. This helps to blend a selection into the surrounding pixels. Noise filters can create unusual textures or remove problem areas, such as dust and scratches, from an image.
1______________Add Noise
Applies random pixels to an image, simulating the effect of shooting pictures on high-speed film. The Add Noise filter can also be used to reduce banding in feathered selections or graduated fills, to give a more realistic look to heavily retouched areas, or to create a textured layer. You can set the amount of noise, the type of noise distribution, and color mode in the filter options.
Uniform creates a subtle distribution effect, and Gaussian creates a speckled distribution effect. The Monochromatic option applies the filter using the existing tones of the image without changing the colors.
2______________Despeckle
Detects the edges in a layer (areas where significant color changes occur) and blurs all of the selection except those edges. This blur-ring removes noise while preserving detail. You can use this filter to remove banding or visual noise that often appear in scans of magazines or other printed materials.
3______________Dust & Scratches
Reduces visual noise by changing dissimilar pixels. See Using the Dust & Scratches filter.
4______________Median
Reduces noise in a layer by blending the brightness of pixels within a selection. The filter searches for pixels of similar brightness, discarding pixels that differ too much from adjacent pixels, and replaces the center pixel with the median brightness value of the searched pixels. This filter is useful for eliminating or reducing the effect of motion on an image, or undesirable patterns that may appear in a scanned image.

Pixelate filters

The Pixelate filters sharply define an image or selection by clumping pixels of similar color values.
5______________Color Halftone
Simulates the effect of using an enlarged halftone screen on the layer. The filter divides the image into rectangles and replaces each rectangle with a circle. The circle size is proportional to the brightness of the rectangle.
To use the Color Halftone filter:
1. Either choose Filter > Pixelate > Color Halftone, or use the Filters palette to apply the Color Halftone filter. (If using the palette, select Filter Options before applying the filter.)
2. Enter a value for the maximum radius of a halftone dot, from 4 to 127 pixels.
3. Enter a screen-angle value between -360 and 360 (the angle of the dot from the true horizontal) for one or more channels:
* For Grayscale images, enter a value in channel 1. Values in the other channel text boxes do not affect the filter.
* For color images, use channels 1, 2, 3, and 4, which correspond to CMYK channels (Cyan, Magenta, Yellow, and Black).
* Click Defaults to return all the screen angles to their default values.
4. Click OK.
6______________Crystallize
Redraws a layer as polygon-shaped clumps of color. You can set the cell size of the 7______________Facet
Redraws a layer as blocks of solid color. You can use this filter to make a scanned image look hand painted or to make a realistic image resemble an abstract painting.
8______________Fragment
Redraws a layer so it appears offset and blurred.
9______________Mezzotint
Redraws a layer as a random pattern of black-and-white areas in a grayscale image, or fully saturated colors in a color image. You can choose a dot, line, or stroke pattern in the filter options.
10______________Mosaic
Redraws a layer as square blocks of color. You can set the mosaic cell size in the filter options.
11______________Pointillize
Redraws a layer as randomly placed dots, as in a pointillist painting, and uses the background color in the toolbox as a canvas area between the dots. You can set the cell size in the filter options.


Render filter

The Render filters create 3D shapes, cloud patterns, refraction patterns, and simulated light reflections in an image. You can also manipulate objects in 3D space, create 3D objects (cubes, spheres, and cylinders), and create texture fills from grayscale files to produce 3D-like effects for lighting.
_______________3D Transform
Maps images to cubes, spheres, and cylinders, which you can then rotate in three dimensions. (See Transforming objects in three dimensions.)
_______________Clouds
Generates a soft cloud pattern using random values that vary between the foreground and the background color in the toolbar.
To generate a starker cloud pattern, hold down Alt (Windows) or Option (Mac OS) as you choose Filter > Render > Clouds.
_______________Difference Clouds
Uses randomly generated values that vary between the foreground and back-ground color in the toolbox to produce a cloud pattern. The first time you choose this filter, portions of the image are inverted in a cloud pattern. Applying the filter several times creates rib and vein patterns that resemble a marble texture.
_______________Lens Flare
Simulates the light refraction caused by shining a bright light into a camera lens. You can set the flare brightness, flare location, and flare shape (the lens type) in the filter options. Click inside the preview window in the dialog box to set the flare location.
_______________Lighting Effects
Lets you produce myriad lighting effects on RGB images by varying 17 light styles, three light types, and four sets of light properties. You can also use textures from grayscale files called texture maps to produce 3D-like effects, and save your own styles for use in other images. (See Using the Lighting Effects filter.)s


EVERYONE>>>> Sharpen filters
Using the Unsharp Mask filter to sharpen photos

The Sharpen filters focus blurry images by increasing the contrast of adjacent pixels.
Sharpen and Sharpen More
Add focus to a selection and improve its clarity. The Sharpen More filter applies a stronger sharpening effect than the Sharpen filter.
Sharpen Edges and Unsharp Mask
Find the areas in the image where significant color changes occur and sharpen them. The Sharpen Edges filter sharpens only edges while preserving the overall smoothness of the image. Use this filter to sharpen edges without specifying an amount. For professional color correction, use the Unsharp Mask filter to adjust the contrast of edge detail and produce a lighter and darker line on each side of the edge. This process emphasizes the edge to create the illusion of a sharper image.

Using the Unsharp Mask filter to sharpen photos
Unsharp masking, or USM, is a traditional film technique used to sharpen edges in an image. The Unsharp Mask filter corrects blurring introduced during photographing, scanning, resampling, or printing. It is useful for images intended for both print and online viewing.
Unsharp Mask locates pixels that differ from surrounding pixels by the threshold you specify and increases the pixels' contrast by the amount you specify. In addition, you specify the radius of the region to which each pixel is compared. The effects of the Unsharp Mask filter are far more pronounced on-screen than in high-resolution printed output. If your final destination is printed output, experiment to determine what settings work best for your image.
For information on other filters for sharpening images, see Sharpen filters.
To use Unsharp Mask to sharpen an image:
1. Choose Filter > Sharpen > Unsharp Mask, and select the Preview option.
Click the preview window in the Unsharp Mask dialog box window to see how the image looks without sharpening. Drag in the preview window to see different parts of the image, and click + or - to zoom in or out.
2. Do one of the following:
* Drag the Amount slider or enter a value to determine how much to increase the contrast of pixels. For high-resolution printed images, an amount between 150% and 200% is usually recommended.
* Drag the Radius slider or enter a value to determine the number of pixels to sharpen around edges. For high-resolution images, a radius between 1 and 2 is usually recommended. A lower value sharpens only the edge pixels, whereas a higher value sharpens a wider band of pixels. This effect is much less noticeable in print than on-screen, because a 2-pixel radius represents a smaller area in a high-resolution printed image.
* Drag the Threshold slider or enter a value to determine how different pixels must be from the surrounding area before they are considered edge pixels and sharpened. To avoid introducing noise (in images with flesh tones, for example), experiment with Threshold values between 2 and 20. The default Threshold value (0) sharpens all pixels in the image.
3. Click OK.


CHALLENGE six: Sketch filters

Filters in the Sketch submenu add texture to images, often for a 3D effect. These filters are also useful for creating a fine-art or hand-drawn look. Many of the Sketch filters use the foreground and background color as they redraw the image.
1_______________Bas Relief
Transforms an image to appear carved in low relief and lit to accent the surface variations. Dark areas of the image take on the foreground color, light areas use the background color. You can set relief detail and smoothness in the filter options.
2_______________Chalk & Charcoal
Redraws an image's highlights and midtones with a solid midtone gray back-ground drawn in coarse chalk. Shadow areas are replaced with black diagonal charcoal lines. The charcoal is drawn in the foreground color, the chalk in the background color. You can set stroke pressure, and the charcoal and chalk areas in the filter options.
3_______________Charcoal
Redraws an image to create a smudged effect. Major edges are boldly drawn, while midtones are sketched using a diagonal stroke. Charcoal is the foreground color, and the paper is the background color. You can set the charcoal thickness, level of image detail, and light/dark balance in the filter options.
4_______________Chrome
Gives the image a polished chrome surface using highlights as high points and shadows as low points in the reflecting surface. You can set the level of chrome surface detail and smoothness in the filter options.
After applying the Chrome filter, use the Levels dialog box to add more contrast to the image. (For more information on adjusting levels, see Using the Levels dialog box.)
5_______________Conté Crayon
Replicates the texture of dense dark and pure white Conté crayons on an image. The Conté Crayon filter uses the foreground color for dark areas and the background color for light areas. In the filter options, you can set the level of foreground and background emphasis, and texture options. For more information on setting the texture options, see Using texture and glass surface controls.
For a more realistic effect, change the foreground color to one of the common Conté Crayon colors (black, sepia, sanguine) before applying this filter. For a muted effect, change the background color to white with some foreground color added to it.
6_______________Graphic Pen
Uses fine, linear ink strokes to capture the details in the original image and is especially striking with scanned images. The filter replaces color in the original image, using the foreground color for ink and background color for paper. You can set the stroke length and direction, and the light/dark balance in the filter options.
7_______________Halftone Pattern
Simulates the effect of a halftone screen while maintaining the continuous range of tones. You can set the halftone size, contrast, and pattern type in the filter options.
8_______________Note Paper
Simulates the texture of handmade paper by combining the effects of the Emboss and Grain filters. Dark areas of the image appear as holes in the top layer of paper, revealing the background color. You can set the image balance, graininess, and relief in the filter options.
9_______________Photocopy
Simulates the effect of photocopying an image. Large areas of darkness tend to copy only around their edges, and midtones fall away to either solid black or white. You can set the level of detail and darkness in the filter options.
10_______________Plaster
Molds the layer into a 3D plaster effect, and then colorizes the result using the foreground and background color. Dark areas are raised, light areas are sunken. You can set the image balance, smoothness, and light direction in the filter options.
11_______________Reticulation
Simulates the controlled shrinking and distorting of film emulsion to create an image that appears clumped in the shadow areas and lightly grained in the highlights. You can set the density, foreground, and background levels in the filter options.
12_______________Stamp
Is best used with black-and-white images. Simplifies the image so it appears stamped with a rubber or wood stamp. In the filter options, you can set the smoothness, and the balance between light and dark.
13_______________Torn Edges
Is particularly useful for images consisting of text or high-contrast objects. Reconstructs the image as ragged, torn pieces of paper, and then colorizes the image using the foreground and background color. You can set the image balance, smoothness, and contrast in the filter options.
14_______________Water Paper
Uses blotchy daubs that appear to be painted onto fibrous, damp paper, causing the colors to flow and blend. You can set the paper's fiber length, brightness, and contrast in the filter options.


Stylize filters

The Stylize filters produce a painted or impressionistic effect on a selection by displacing pixels and heightening contrast in an image.
_______________Diffuse
Shuffles pixels in a selection to make the selection look less focused according to the option you select: Normal moves pixels randomly, ignoring color values; Darken Only replaces light pixels with darker pixels; Lighten Only replaces dark pixels with lighter pixels; and Anistropic softens all pixels.
_______________Emboss
Makes a selection appear raised or stamped by converting its fill color to gray and tracing the edges with the original fill color. You can set the embossing angle, height, and a percentage for the amount of color within the selection.
_______________Extrude
Gives a 3D texture to a selection or layer. See Extrude Filter for more information.
_______________Find Edges
Identifies areas of the image with significant transitions and emphasizes edges. Like the Trace Counter filter, Find Edges outlines the edges of an image with dark lines against a white background and is useful for creating a border around an image.
After using filters like Find Edges and Trace Contour that highlight edges, you can apply the Invert command to outline the edges of a color image with colored lines or a grayscale image with white lines
_______________Glowing Edges
Identifies the edges of color and adds a neon-like glow to them. You can set the edge width, brightness, and smoothness in the filter options.
_______________Solarize
Blends a negative and a positive image--similar to exposing a photographic print briefly to light during development.
_______________Tiles
Breaks up an image into a series of tiles, off-setting the selection from its original position. In the filter options, you can set the number of tiles and the offset percentage. You can also choose one of the following to fill the empty area between the tiles: Background Color, Foreground Color, Inverse Image, or Unaltered Image, which puts the tiled version on top of the original and reveals part of the original image underneath the tiled edges.
_______________Wind
Creates tiny horizontal lines in the image to simulate a wind effect. You can set the wind strength and direction in the filter options.


Extrude Filter

_______________, _______________

The Extrude filter gives a three-dimensional texture to a selection or layer.
To use the Extrude filter:
1. Either choose Filter > Stylize > Extrude, or use the Filters palette to apply the Extrude filter. (If using the palette, select Filter Options before applying the filter.)
2. Choose a 3D type:
* Blocks creates objects with a square front face and four side faces.
* Pyramids creates objects with four triangular sides that meet at a point.
3. Enter a value in the Size text box to determine the length of the object's base, from 2 to 255 pixels.
4. Enter a value in the Depth text box to indicate how far the tallest object appears to protrude from the screen, from 1 to 255.
5. Choose a depth option:
* Random to give each block or pyramid an arbitrary depth.
* Level-based to make each object's depth correspond to its brightness--bright objects protrude more than dark.
6. Select Solid Front Faces to fill the front face of each block with an averaged color of the block. Deselect Solid Front Faces to fill the front face of each block with the image. This option is not available for Pyramids.
7. Select Mask Incomplete Blocks to hide any object extending beyond the selection.
8. Click OK.

The Displace, Shear, and Wave filters in the Distort submenu and the Offset filter in the Other submenu let you treat areas undefined by the filter.

Trace Contour

_______________, _______________

Trace Contour finds the transitions of major brightness areas and thinly outlines them for an effect similar to the lines in a contour map.
To use the Trace Contour filter:
1. Either choose Filter > Stylize > Trace Contour, or use the Filters palette to apply the Trace Contour filter. (If using the palette, select Filter Options before applying the filter.)
2. Select an Edge option to outline areas in the selection: Lower outlines where the color values of pixels fall below the specified level, and Upper outlines where the color values fall above.
3. Drag the Level slider to specify the edge level for evaluating color values. Experiment to see what values bring out the best detail in the image.
Use the Info palette in Grayscale mode to identify a color value that you want traced. Then enter the value in the Level text box.

Using effects :
The Effects palette lets you quickly create different looks for your images.
If an effect name is followed by (Selection), (Layer), or (Type), the effect can only be applied to a selected portion of your image, to a selected layer, or to a type layer, respectively. Some effects are automatically applied to a copy of the selected layer, while other effects can only be applied to a flattened image. You cannot preview layer effects or change options for the effects.
Many of the choices in the Effects palette are modified versions of filters--giving you a default value of a filter. See Choosing a filter to decide whether to use an Effect or a Filter.
To apply an effect:
1. Do one of the following:
* To apply an effect to an entire layer, deselect any selected areas in the image, and then select the layer in the Layers palette.
* To apply an effect to a portion of a layer, use any selection tool to select the area.
* To apply a Text effect, use the text tool to enter the text you want.
2. Do one of the following in the Effects palette:
* Double-click an effect.
* Select an effect, and click Apply.
* Drag an effect to the image.
Note: In some cases, when applying an effect to an image with multiple layers, you are prompted to flatten the image first.

Frames effects
Frames effects apply a variety of effects to the edges of a selected layer, or to a portion of a layer.
The Vignette effect, for example, creates a separate layer from a selected portion of an image. Using any selection tool, select a portion of the image and apply the Vignette effect. The results are two new layers added to the image--a white layer appearing to frame the new vignette layer. You can either flatten the image, or drag the vignette layer to another image.

Textures effects
Texture effects apply texture layers to an image. You can add texture to a new, blank image as a background, or add a texture to an existing image. By arranging layers, and working with opacity and other layer tools, you can create interesting and attractive images.

To apply text effects:

1. Select the text tool and type a caption or message in your image. (The text is added as a new layer.)
2. Choose a Text effect and drag it to the text in your image. You can reposition the text if needed.

Image effects
Image effects apply an effect to a copy of a selected layer. Adding the Blizzard effect to an image makes it look like it's snowing. The Neon Glow effect turns the image into a dramatic neon picture. You can use Image effects such as Oil Pastel or Soft Focus to soften colors or blur an image. You can also combine Image effects, but you may be prompted to flatten layers first.
