How Do I Turn On Auto Blend Layers in Photoshop?

To turn on Auto-Blend Layers in Photoshop, follow these steps:

1. Select All Layers: Click on the bottom layer in your Layers panel. Then, hold down the Ctrl key (or Cmd key on a Mac) and click on the top layer to select all the layers you want to blend.

2. Access Auto-Blend Layers: Go to the Edit menu in the top menu bar and choose Auto-Blend Layers....

3. Choose Blending Option: In the Auto-Blend Layers dialog box, select the radio button next to Stack Images. This option is typically used for seamlessly blending images, like panoramas or focus stacks. Other options may be available depending on your desired outcome.

4. Confirm and Apply: Click OK. Photoshop will automatically apply masks to the layers and blend them together based on the chosen blending method and content.

Essentially, Photoshop analyzes the selected layers and creates layer masks to seamlessly blend them based on their content and the specified stacking method. This feature is incredibly useful for tasks like creating panoramas, focus stacking for enhanced depth of field, and compositing multiple images.
