Scanning 48->24 bit but file opens in Photoshop as 8 bit

Postby lookingforbits » Thu Nov 07, 2013 9:56 pm

I am scanning photographs using the following specifications:

SilverFast SE Plus + Epson Perfection V750 Pro scanner

Software settings:
Reflective
Positive
48->24 bit
PSD format
1200 dpi

When I open my images in Photoshop, they open as 8 bit files.

Does this mean my scanned image files are actually 8 bits, or is Photoshop incorrectly reading my files?

Thanks for your help.

Dear customer,

This is correct.
Photoshop states the bit-depth per RGB channel (3 x 8 = 24)

SilverFast shows the combined bit depth.

kind regards,
Arne Ketelhohn.
