When someone contacts me needing the photo of a loved one repaired sometimes one of the main issues is how the photograph is reproduced. Could be a bad scan, or maybe they photographed a print while still in a frame under glass. Restoration and repair of old photos isn’t always due to scratches, torn corners or mold. Often times just about all of the issues are taken care of with the majority of the clone tool in Photoshop, but faded areas and flash photos of a glossy print can provide more difficulty for the restoration process.
