“While it is certainly possible to fix and enhance your old photos at home, it takes a scanner and the appropriate image editing software (Photoshop is the gold standard) and some skill, patience and practice. Restoring photos is painstaking work.
A good photo restorer will use cloning and healing tools to repair blemishes and scratches on the digitized image rather than just smoothing them out, which may change the look of the photo or make it look more like a painting.
In some instances areas of the original photo are so damaged that important parts are missing. A skilled photo restoration service can use imaging software to re-create the missing sections or to paint them in. Most services will also colorize B&W photos and change or remove backgrounds and objects.”
“Sometimes the best anyone can really hope for is that these types of images will be at least a little improved after being digitally retouched,”
