Panoramics can be constructed in many ways. Today we will explore the quick
way using Photoshop's Photomerge as well as a more accomplished technique required
for those composites that just don't fit together.Much of your success will
depend on the photos you take for the panoramic. Obviously the best way is to
use a tripod, and take pictures so that 25% of the photo overlaps with the next
frame. Also you want the lighting/exposure to be the same for all the frames.
However reality dictates that the exposure will not be equal as you move from
north to south, and most likely you don't own a tripod ( or like me) are too
lazy to carry around with you.
Sometimes the worst scenario occurs when as in museums, you can't use a tripod,
the lighting is awful and you get jostled from every angle. Photoshop may or
may not salvage your efforts.. as you will find out as you complete the two
projects for today's class.
You'll need to download on your machine set one ( church) and set two ( aquincum dig)
Set One: easy reconstruction |
Set Two: Dig- difficult reconstruction |
In each case you will eliminate one of the images.
1. Easy techniques: Photomerge
Stitch together a panorama
Have you ever taken a series of photos and tried to piece them together to form
a panoramic image? Well, put away the tape and glue. Adobe® Photoshop®
Elements 2.0 has a Photomerge™ command that combines several photographs
into one continuous image for you. In this tutorial, you'll see how to assemble
the photos you want to include in a panoramic image, and how to refine the image
that Photoshop Elements creates.
1. Specify the photos for a panorama.Choose File > Create Photomerge. Then
click Browse and navigate to the "cars_pano" folder in the Tutorials
folder located inside the Adobe Photoshop Elements application folder. Open
the folder and select all the image files. (Hold the Shift key and click on
each image to select all files.)
Click Open to add the images to the Source Files list in the Photomerge dialog
box.
When the images are added to the Photomerge dialog box, click OK.
Photoshop Elements creates a panoramic image from the individual images and
displays the new panorama in the Photomerge dialog.
2. View the composition.To change your view of the composition, use the Navigator.
Position the pointer in the red box in the Navigator thumbnail. Drag the red
box over the area of the composition you want to view. Use the zoom-out or zoom-in
button, or drag the slider bar to adjust the magnification of your composition
in the work area
.
3. Adjust the perspective of the composition.The perspective must be established
for your photos to successfully merge into a continuous image. Photomerge establishes
the initial perspective.
If you need to change the perspective, select the Perspective option in the
Settings area. Then select the set vanishing point tool and move the pointer
over your composition in the work area. Click one of the images to assign a
location for the vanishing point.
Since your panorama is viewed from a frontal position, try locating your vanishing
point at the center of your composition. A blue box appears around the image
used to establish the perspective for your composition. The images not used
for the perspective have a red bounding box when you click them.
Sometimes it's difficult to set a new vanishing point or to grab an image that's
obscured by another overlapping image. Hold down Alt (Windows) or Option (Mac
OS) as you move the pointer in the work area. The image, whose center is closest
to the pointer, is highlighted. You can then click to select the image.

4. Align the images.If the images in your composition don't line up the way
you want them to, you can align them using the select image tool and the rotate
tool. Deselect Snap to Image before adjusting alignment.
5. Balance exposure differences.Select Advanced Blending, and click Preview.
Advanced Blending balances the exposure differences between the source images.
When working on your own compositions, you would select the Cylindrical Mapping
option if you have a "bow tie" distortion in the overall shape of
your composition. You can apply both Advanced Blending and Cylindrical Mapping
options.
Once you've finished viewing the preview image, click Exit Preview to finish
merging your composition.

6. Generate the panorama.When you're satisfied with your composition, click
OK in the Photomerge dialog box.
7. Put the final touches on your panorama.Photomerge generates your panoramic
image as a new, editable Photoshop file. You can crop any irregular edges or
unwanted portions from your composition. And you can also use any filter, painting
tool, or editing tool to fine-tune your image.
In our automobile panorama, we used the burn and dodge tools, the Sharpen filter,
and the clone stamp tool to remove blemishes and enhance our composition.
2. Not so easy: manual stitching of images for a panoramic: see xeroxed notes.
