Photo restoration using cropping
When carrying out a photo restoration cropping can play its part. Cropping a photo is cutting off pieces you don’t want. When an image is scanned to a computer the edges may contain information you don’t want. For example the frame around the edge, or a very torn edge, or maybe an area of little importance.
Cropping can be used to alter the composition of a photo, or straighten the edges. It may be that you are working on a larger area and your painting or corrections spill over the edges of a photo. The crop tool will neaten these up in just a few clicks.
