Auto blend layers
Use the Auto-Blend Layers command to stitch or combine images with smooth transitions in the final composite image. Auto-Blend Layers applies
layer masks as needed to each layer to mask out over- or underexposed areas or content differences. Auto-Blend layers is only available for RGB
or Grayscale images. It does not work with Smart Objects, video layers, 3D layers, or background layers.
Among the many uses of the Auto-Blend Layers command, you can blend multiple images of a scene with different areas in focus to achieve a
composite image with an extended depth of field. Similarly, you can create a composite by blending multiple images of a scene with different
illuminations. In addition to combining images of a scene, you can stitch together images into a panorama. (Although, it might be better to use the
Photomerge command to produce panoramas from multiple images.)
Auto-Blend Layers applies layer masks as needed to each layer to mask out over- or underexposed areas or content differences and create a
seamless composite.
