Using Auto-Align
You can use Auto-Align to align layers for the purpose of creating composites. By stacking, aligning, and masking sets of nearly-identical images in the Layers pane, you can omit unwanted areas while exposing select areas to create one optimal version of the image.
After aligning, you can use layer masks to create an ideal composite.
To Align Multiple Layers:
- Shift-click or Ctrl-click to select multiple images in the Layers pane.
- Choose Layer | Auto-Align Layers.
The Auto-Align command will only align vertically. Therefore, attempting to align panoramas or dissimilarly-sized images will yield undefined results.
Running the Auto-Align command on large images will require a significant amount of memory.
