Roger mentioned Kodak Photo CD format. Years ago, before I had a digital camera and was still using film to get slides, Kodak had an arrangement whereby when the slides were developed they would produce a Photo CD with the same images. I tried this with four rolls of film. The slides were wonderful; the CD images were out of focus. Not grossly out of focus, but upon close examination finer details were out of focus. That was the end of my interest in that product. Perhaps they have gotten better at it. I've often noticed a similar degradation in detail when I've had slides reproduced. I'll be watching postings on this thread with interest because I have thousands of slide images taken between 1960-2000 which I would like to scan. Jim McKenney
