Fixing staircasing or the
Sometimes an image suffers from staircasing edges or the jaggies. There are two methods I use to fix this. The first is using the Smudge tool at 50% opacity and drawing around the staircased edges. Another option is to use the Clone tool to fix jagged edges. One option for dealing with a grainy image is to look at the various color channels and see if one of the channels is causing more noise then some of the other channels. The yellow channel is not typically anything to worry about because it is so light; it's the other channels you have to worry about.
