It's me again...
The scanner is a HP ScanJet 2400, and wherever I look on the Net, it is said to support 48 bit color mode.
But however I try, even with it's own scanner software, the bitdepth selections are limited to: Millions of colors, 256 color, 256 gray shades, 1 bit BW.
I know JPEG's limitations, I scan to TIFF (or compressed TIFF).
The output image will be 24 bit only.
So, the trick I want to use is essential for me, because I have no money now for a new scanner. But you are all can feel free to send me one if you don't need it anymore
Initiate the scan from Photoshop, and there is a check box hidden in the driver settings to enable 16 or 48-bit output for clients that support it. Your mission, should you accept it is to find that check box and enable it. Make sure you have tha latest drivers installed also.
