Do digital images captured in cameras (either still or video) suffer in image quality when they are successively copied or edited?

Copying an image a number of times does not cause any harm to the image. But editing it repeatedly or extensively results in a loss of quality. You will not be able to see the difference the first few times, but after you re-edit a photograph a number of times, you will realize that the quality of the photograph has started degrading. If you preserve the original file from your camera, you can always edit a copy of the original image for the best quality.
