result. See "Create a photomerge interactively" on page 241.
Select Blend Images Together (the default) if you want Photoshop to find the optimal borders between the images
5
and create seams based on those borders, and to color match the images. With Advanced Blending off, a simple
rectangular blend is performed. This may be preferable if you intend to retouch the blending masks by hand.
6 When you've added all the source files, click OK to create the Photomerge composition.
If the composition can't be automatically assembled, a message appears on-screen. You can assemble the composition
manually in the Photomerge dialog box using the lightbox.
Photoshop creates one multi-layer image from the source images, adding layer masks as needed to create optimal
blending where the images overlap. You can edit the layer masks or add adjustment layers to further fine tune the
different areas of the panorama.
Create a photomerge interactively
Choose the Interactive Layout option in the main Photomerge dialog box to open the Photomerge interactive dialog
box, where you can manually rearrange your source images to create a panorama.
With Reposition Only and Snap to Image selected, Photoshop will preserve alignment at overlapping image areas,
and apply blending to even out differences of exposure between the images. In Perspective mode, Photoshop selects
one of the source images to supply a vanishing point, and stretches or skews the other images to create a wraparound
effect. Use the Vanishing Point tool to change the vanishing point and reorient the perspective.
• After arranging the composition, click OK to generate the panorama as a new Photoshop file. The composition
then opens in Photoshop.
• Click Save Composition As to save the composition and open it again at a later time.
