how to scan images with very dark parts

[philllie1]

since no luck in the tips&tricks forum, I try it over here.
from Lasersoft anyone?

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

philllie1,

The "Histogram" in SilverFast will allow you to adjust the image tonality. You will do well to create three scans; highlights, mid-tones, shadows, in order to get better results with Photoshop?s Merge To HDR.

I think you will still find noise in the images and recommend that you give "Noise Ninja" (Photoshop plug-in) a try.
