Colour cast scanning trannies on Epson 3200

[ken munn]

Hi,

 

Please see the attached. It is a section of a 645 transparency of a painting I scanned for inclusion in a

catalogue. I photographed it with a white, black, grey reference (seen here at the top) in shot. After the

pre-scan I used the Epson Scan app's histogram function to set the black, white and mid points using the

eyedropper. The result is what you see at the top of the attachment - it has a distinct red colour cast. The

bottom section of the attachment is after correction using CS3's level controls.

 

Can anyone suggest why the Epson would scan with a colour cast (which wasn't visible on-screen in the

preview)? Is this inherent with the 3200? Am I doing something wrong? Should I forget about trying to set

levels on the pre-scan and just do everything in CS3 afterwards?

 

Thanks for any help.<div></div>

I do lots of transparency scanning. I do all adjustment post-scan in PS CS2.
