Dear sgelb

Perhaps we can help you further if you provide us with a little description of your equipment, SilverFast version as well as the material you are scanning and the procedure every picture undergoes.

Thank you

Dear sgelb

For us and other users being able to provide some help we would need a description of your material,
How big are the originals?
What type of film is that you are scanning?
Which film holder are you using?
Are you using liquid mounting?
Which NegaFix profile you have?

Also some screenshots of the preview and endscan would be nice to help understand you.

Thanks for your cooperation
