Stitching Photos
I just ran outside with my digital camera and took five photos of a camphor tree growing next to my house. As shown in Figure 36-1, the five photographs all contain portions of the tree.

Using the Photomerge command, I’m putting them all together into one giant tree image:
Open the photographs you want to merge into a panorama or photomontage.Or, if you like you can use the Photomerge dialog box to select files or folders later.
Choose File>Automate>Photomerge.The Photomerge dialog box, shown in Figure 36-2, appears.

Choose a source for the image files with the Use drop-down list.Select from:
Open Files: Automatically places all files open in Photoshop into the file list.
Files: Lets you select individual image files.
Folder: Lets you select an entire folder full of image files.
If you chose Files or Folder in Step 3, click Browse to locate the files or folders you want to use.
Click OK after you select all the image files you want to use.The large Photomerge dialog box opens displaying all the image files you selected, as shown in Figure 36-3. Photomerge places any images it can’t match together in the lightbox area.

Drag images from the lightbox down into the workspace, trying to match the photographs together as best as possible. (Don’t worry; you don’t have to be perfect!)When you release the mouse, Photoshop detects where the photographs are the same and automatically snaps the photographs together. (Isn’t that great?!)
Select Perspective in the Settings area, if you want to change the perspective of the image and add a vanishing point.If you do choose Perspective, select the Vanishing Point tool from the left side of the Photomerge dialog box. In the workspace, click the image you want to use as the vanishing point. Photoshop goes to work adjusting the perspective as shown in Figure 36-4.

Put a check in the Cylindrical Mapping check box to remove the stretched distortion that can occur when creating a panorama, if you want.Cylindrical Mapping is available only if you select the Perspective option in Step 7.
Put a check in the Advanced Blending check box to set Photomerge to reduce the color inconsistencies from photo to photo.
Click Preview.Photomerge recolors and blends the photos together, adding perspective and cylindrical mapping if you selected it.
Click Exit Preview.
Put a check in the Keep As Layers check box if you want to place each photograph on a separate layer.If you don’t select this option, Photomerge automatically places all the photos together onto one layer.
If you want, you can save the panorama or photomontage by clicking the Save Composition As button and using the Save dialog box to select a folder and enter a filename.
Click OK.The Photomerge dialog box closes and Photoshop goes to work placing the new panorama or photo montage in a new image window, as shown in Figure 36-5.
