How to scan slides with quite dark areas?

[philllie1]

Hi
I have some slides that have some dark areas in it....when I brighten them up in photoshop after scanning i get in some parts quite ugly parts that are very grainy and have a magenta color cast. can I avoid them somehow?
I read that some people scan twice (once for the highlights, once for the dark areas) and than combine in photoshop .... but I cant find an option to control exposure...
also i tried auto-image that controls the light well...but changes colors of my images into something terrible.
I also tried 16xmultiscan, but it didn't help
Would appreciate your help

Dear philllie1

to exterminate multiple colour casts, you might want to use the midpip4 pipette tool. Its uses are explained in the manual, "Ch5.02 Highlight-Shadow Tool" (PDF, 1.85 MBytes).
A demonstration video is also available.

hi phillie

another suggestion is:

1. do use the multi scan - especially when the dar areas in slides are oimportant to u.
2. use the gamma properly.
3. make your adjustmentsas u would like to have midtones and highlights.
4. now use the "aaco" cunction.

this will give you a much better chance to get your image. but it needs experimenting and getting used to the "reaction" of aaco in different adjustment settings.
