Hi,
I have a Epson Perfection 4990 photo. When I scan negativs in 48>24 bit all works fine but whwn I change to 48 bit HDR color mode ore 64 bit HDRi Color mode my scans turn negative. I save the scans as tiff.
What is going wrong?
Best Regards

Dear Rex,

There is nothing going wrong.
48bit HDR and 64bit HDRi are raw image formats for our ArchiveSuite workflow.
They are saved unchanged and are menat to be processed in our SilverFast HDR (studio) software.

kind regards,
Arne Ketelhohn.

Ah, thanks!
I knew I shuld process via Silverfast HDR but I didn´t know I hade to work with negativefilm format. Now a bell is ringing .
Thanks again!
