Photoshop

Use a script to create an image stack (Photoshop Extended)

You can use the Statistics script to automate creating and rendering an image stack.

  1. Choose File > Scripts > Statistics.
  2. Choose a stack mode from the Choose Stack Mode menu.
  3. Apply the stack mode to currently open files, or browse to select a folder or individual files.

    Files you select are listed in the dialog box.

  4. Select whether to automatically align images (equivalent to choosing Edit > Auto-Align Layers) and click OK.

    Photoshop combines the multiple images into a single multilayered image, converts the layers into a Smart Object, and applies the selected stack mode.
