Originally posted by edmundrt Ektar is frustrating even with a scanner - for me, using an Epson 550, it's about a 50% hit rate for accurate colour rendition, my most common complaint being scans that come out with a distinctly blue cast. I have had the same thing happen with Portra 160 and 400, but never with any of Kodak's consumer colour films, nor any Fuji emulsions, which makes me wonder if there is something about the backing on Kodak pro films that confuses scanners.
My scanner is an older Epson 4990, which was Epson's top of the line model prior to the release of the V7xx models. I've had very good results with all emulsions, including Portra -- especially Portra, in fact --
except Ektar. My Ektar scans don't usually have a blue cast. Mine are somewhat more subtle. Earthtones, such as light browns and tans take on purple casts. It's a fairly easy process to correct this in post, but it's obvious enough where it has to be corrected. Trying to dupe Ektar is another matter entirely, though. The reversed images take on way too much cyan and, no matter how hard I try, I can't get rid of it all. I'll have to give this other method a try -- maybe it will help with the cyan some.
