Getting an accurate before-and-after comparison
Use images with matching framing and aspect ratio whenever possible. The tool scales the second image to the first image dimensions so the same locations line up. A horizontal slider is useful for portraits and product edits, while a vertical slider can reveal changes across wide scenes.
