This tutorial deals with repairing rips, scratches,
and improving the overall quality of an older image.
The author does a good job of explaining use of the
spot healing tool and the clone stamp tool - When to
use them and when not to. He speeds up some of
the repair work to save your time. Once repaired he
shows how to use, adjustment layers for levels,
black and white and hue and saturation to tweak the
over look of the photo.
