Hi.

I've been scanning all my images since I got SilverFast as CMYK-16bit, but recently some people started complaining that the images are too big and have a lot of extra data that should not be scanned... I'm a graphical designer/photographer (dont check gallery, never updated) and usually scan the images for storage and later quick retrieval.

My question is this.. for this kind of job, what would be more usefull, RGB or CMYK and 8bit pr 16bit per channel? some programs cannot show thumbnails of CMYK16 (thumbs plus) so I get a generic icon... of course the negatives could later be retrieved for professional use and re-scanned... but that's something that I would like to avoid... so... what colour model for what?

RGB-8?, RGB-16?, CMYK-8?, CMYK-16?

Thanks in advance
