LaserSoft Imaging

Hi,

I scanned some slides with sF Ai (Digitdia4000) in 48 bit color and 48 bit HDR mode.

HDR mode seems to be ok: SF HDR (demo version up to now only) can read the files, also some fileviewers as MS, IrfanView and some LInux viewers.

48 bit color file are not readable by most viewers at all or show black pictures only; not even SF HDR accept these files.

Is this behaviour due to my handling error or intended?
What the 48 bit mode can be used for?

Tnx for an answer

Hallo Guenter,

For clarity, 48-bit mode is three 16-bit channels (Red, Green, Blue), which provides more image data.

It is my understanding that 48-bit images are commonly used for:
1) Archive images
2) Image manipulations (i.e. restorations, compositions)

Most, if not all, Web and printed images are currently only 8-bit due to hardware and software limitations, but this could of course change in the future. SilverFast and Photoshop currently handle 48-bit (called 16-bit in PS), and Photoshop also provides limited support for 32-bit (AKA 96-bit) images.
