Thanks for the quick response. Which demo should I first download and try out? The 48-bit HDR version or "Silverfast for scanners"? Or can "Silverfast for scanners" also incorporate 48-bit HDR work? I have an Epson Perfection V500, by the way. Also, I am not wedded to Photoshop, except for its Lightroom cousin; I much prefer to use Paint Shop Pro X2 for my basic photo finishing, though I can accomplish just about all I need with Lightroom alone. Not all my work is shot in RAW mode, although some is. My immediate need is software to help me move decades of 35mm slides and negatives into digital format for long-term storage, and to do it elegantly. Thanks again.
