    I need your Help!

    Please check out the waterfall photo. This is a scan of a FP4 neg developed in PyroCat HD. All the negs that I have tried to scan that are process this way look really weird. They almost look posterized. The contrast is all screwed up.

    I am using an Epson 2450 with Silverfast SE scanning software.

    Check to see what you are scanning in and outputting as:

    i.e. make sure you scan as 16bit Grayscale or 48bit RGB and that you are also outputting this way.

    I don't know about Silverfast, but in Vuescan you have to set both of these independently.

    I use almost exclusively FP4+ with either Rodinal or D-D23 and I have had several that scanned just like that but printed just fine on MGIV Perle.

    all the negs that I have dev'd in HC110 or Rodinal scan just fine. It's only the pyro negs that are messed up.

    It is the stain that is messing things up. I don't know why, but since they print beautifully who cares right? Try scanning as a color neg not a BW neg. Might make a difference.

    I agree - I think it's a settings issue in Silverfast, where the defaults are being confused by the color of the stain. If you check curves in Silverfast, my guess is that the curve is back-tracking on itself, causing the posterization or near-solarized appearance.

    I usually scan as 48-bit RGB, rather than greyscale, but sometimes have to scan as a positive, and then invert in Photoshop. Part of that trick is to remember that the settings values in Silverfast are reversed. I also ignore the Epson instructions for my 3200 to scan emulsion side up. I put the emulsion side down, as you would in an enlarger, and then flip the image in PS. Much sharper that way (no surprise, eh?).

    If they print well, why scan the negative? Give us prints!

    end snip

    Ralph makes a very good point, with my tinker-toy scanner it makes all the difference in the world which side is up. Try and scan the other side once.
