I am trying to restor a very old family picture (black and white) with a lot of cracks and areas of overexposure and simply worn parts. The picture overall looks dull and neutral, and low contrast. What are the things I can do to make it better on print. I am using Photoshop CS3. Please advice,. And what is the best way to scan the picture. I can send the picture of somone wants to look at it.
