The guide dots also moved around a bit as I tried to line them up properly, making it difficult to scan pictures quickly. In some instances, I had to scan my photo more than once to get it to register properly. But scanning Polaroids proved trickier, perhaps because of their smaller size. PhotoScan worked well during a demonstration with regular printed photos. That reduces the glare you might get when taking a single photo from one particular angle. The app then takes multiple individual images and stitches them together. When scanning a photo, Google’s app asks you to line up a circle in the center of the screen with four dots located near the corners of the photo.
