I have an Epson 700 Perfection scanner and I want to scan my old slides and negatives to raw. I can't figure out how to so it in the software that came with the scanner (Epson & Silverfast). Is there a way to scan directly to raw in these programs or do I need to scan from Photoshop or Corel? Also is there a .raw file format or does "raw" cover many formats? If yes which one should I use?
