The problem shots are underwater images which include a deep blue background but end up pea green. Shots that do not include a blue background. All I can suggest is try Vuescan. When I had an LS1000 it gave far more neutral results than NS, though I never tried it with Silverfast.

mahimahi wrote I also use a Acer 2720s which the factory software includes a film type selector. This helps a little but when scanning Fuji NPC 160 (which is not included in the list of film types) produces similar green output. With the Acer (don't know about the Nikon), it's possible to adjust an existing film-type (check Pete's Photoscientia site for details), and save the changes as a film-type, in Miraphoto. It would take a bit of playing, but hopefully you'd only have to do it once. (I haven't tried it, myself, and am taking Pete's word about the changes methods).

Try Vuescan with Color balance Neutral or None on the Color tab perhaps?

I've no experience with underwater images, but you may be interested in pages 135-138 of Dan Margulis' book Professional Photoshop 6. He is essentiallu suggesting blending channels and using lighten blend mode.

Re: filmscanners: Color Cast removal/and blue blues
Make up a couple of layers that blend about 50% opacity wise for colour. In the first one, chop out the whale and make the whole layer into a filter that gets the background colour right. In the second one chop out all except the whale and do the same thing. Sounds hard if you've never done it. Isn't. Even Photo Deluxe does this OK for those of without the wherewithal to own PS IB At 16:55 28/06/01 -0700, you wrote: I've no experience with underwater images, but you may be interested in pages 135-138 of Dan Margulis' book Professional Photoshop 6.
