Jan No idea about what process might have been used. I know little of anything about photography. I did notice that that company, while doing restoration and webhosting also maintains/keeps your videos and photo whereby they can later sell more services. This idea I do not endorse in any way. If they are my pictures, they are mine. They can say they are yours but they maintain possession and control. I have hours of 8mm home video to move to DVD but I won't allow someone else charge me a fee and then keep my material. As far as your old picture goes, I would go to a reputable photo shop but also make certain that you get all materials. Professional photographers have this same practice, artististic license or something, but will sell the negatives.
