Create A Photomerge Composition - Adobe Photoshop CS6 User Manual

different exposures, but extreme differences make alignment difficult. Some digital cameras change exposure settings automatically as you take
pictures, so you may need to check your camera settings to be sure that all the images have the same exposure.

Create a Photomerge composition

1. Do one of the following:
Choose File > Automate > Photomerge.
In Adobe® Bridge, choose Tools > Photoshop > Photomerge from the Bridge menu bar. Skip to step 5.
Note: In Bridge, choosing the Photomerge command uses all images currently displayed in Bridge. If you only want specific images
used, select them before choosing the Photomerge command.
2. Under Source Files in the Photomerge dialog box, choose one of the following from the Use menu:
Files Generates the Photomerge composition using individual files.
Folders Uses all the images stored in a folder to create the Photomerge composition.
3. Specify which images to use by doing one of the following:
To select image files or a folder of images, click the Browse button and navigate to the files or folder.
To use the images currently open in Photoshop, click Add Open Files.
To remove images from the Source File list, select the file and click the Remove button.
4. Select a Layout option:
For a video that shows the effect of each Layout option, see www.layersmagazine.com/photoshop-cs4-photomerge.html.
Auto Photoshop analyzes the source images and applies either a Perspective, Cylindrical, and Spherical layout, depending on which
produces a better photomerge.
Perspective Creates a consistent composition by designating one of the source images (by default, the middle image) as the reference
image. The other images are then transformed (repositioned, stretched or skewed as necessary) so that overlapping content across layers is
matched.
Cylindrical Reduces the "bow-tie" distortion that can occur with the Perspective layout by displaying individual images as on an unfolded
cylinder. Overlapping content across files is still matched. The reference image is placed at the center. Best suited for creating wide
panoramas.
Applying Cylindrical Mapping

Spherical Aligns and transforms the images as if they were for mapping the inside of a sphere. If you have taken a set of images that cover
360 degrees, use this for 360 degree panoramas. You might also use Spherical to produce nice panoramic results with other file sets.
Collage Aligns the layers and matches overlapping content and transforms (rotate or scale) any of the source layers.
Reposition Aligns the layers and matches overlapping content, but does not transform (stretch or skew) any of the source layers.
5. Select any of the following options:
Blend Images Together Finds the optimal borders between the images and create seams based on those borders, and to color match the
images. With Blend Images Together turned off, a simple rectangular blend is performed. This may be preferable if you intend to retouch the
blending masks by hand.
Vignette Removal Removes and performs exposure compensation in images that have darkened edges caused by lens flaws or improper
lens shading.
Geometric Distortion Correction Compensates for barrel, pincushion, or fisheye distortion.
6. Click OK.
