- Replace or delete parts of images that have the same background. After aligning the images, use masking or blending effects to combine parts of each image into one image.
- Stitch images together that share overlapping content.
- For video frames shot against a static background, you can convert frames into layers, then add or delete content across multiple frames.
1. Copy or place the images you want to align into the same document. Each image will be in a separate layer. See Duplicate layers.
Note: You can load multiple images into layers using a script. Choose File > Scripts > Load Files into Stack.
2. (Optional) In the Layers panel, create a reference layer by locking it. See Lock layers. If you do not set a reference layer, Photoshop will analyze all the layers and select the one at the center of the final composition as the reference.
3. Select the remaining layers you want to align. To select multiple adjacent layers from the panel, Shift-click; To select noncontiguous layers, Ctrl-Click (Windows) or Command-click (Mac OS).
Note: Do not select adjustment layers, vector layers, or Smart Objects that do not contain information needed for alignment.
4. Choose Edit > Auto-Align Layers, and choose an alignment option. For stitching together multiple images that share overlapping areas—for example, to create a panorama—use the Auto, Perspective, or Cylindrical options. To align scanned images with offset content, use the Reposition Only option.
Photoshop analyzes the source images and applies either a Perspective or Cylindrical layout, depending on which produces a better composite.
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.
Reduces the “bow‑tie” distortion that can occur with the Perspective layout by displaying individual images as on an unfolded cylinder. Overlapping content across layers is still matched. The reference image is placed at the center. Best suited for creating wide panoramas.
Aligns images with wide fields of view (vertical and horizontal). Designates one of the source images (the middle image, by default) as the reference image and spherically transforms the other images so that overlapping content is matched.
Aligns layers and matches overlapping content, without changing the shape of the objects in the image (for example, a circle will still be a circle).
Aligns the layers and matches overlapping content, but does not transform (stretch or skew) any of the source layers.
Automatically corrects for lens defects:
Compensates for a lens defect that causes the edges, especially the corners, of an image to be darker than the center.
Compensates for barrel, pincushion, or fisheye distortion.
- Note: Geometric Distortion will try to take into account the radical distortion to improve the result of the alignment, except with fisheye lens; when fish eye metadata is detected, Geometric Distortion will align the images for fish-eye
