Hi Austin,

Yes, uncompressed TIFF works as well as the various raw formats. I've never used a compressed TIFF format. The Imacon RAW file is actually delivered in TIFF file format. For those out there wondering about what I'm saying... the data is 'raw scanner data' put into a TIFF file format. It's called .fff (Flexible File Format) which can be read and written by Photoshop and Lightroom. And believe me, when you open a .fff file, you instantly know that it is truly unadulterated RAW data.

BTW, VueScan delivers its RAW data in the DNG format. Adobe programs love it!

Hi Jim,

TIFF is good ;-)  I either do raw or TIFF, never JPG.

Adobe Camera Raw reads/opens Imacon RAW files. A Canon RAW file is different than a Nikon RAW file and is different than an Imacon RAW file and is different than a RAW file from a Microtek or Nikon scanner, but ACR reads them. There is ABSOLUTELY no difference in data coming off of a camera sensor or a scanner sensor. It is analog pixel data, run through an A/D converter, fixed with PRNU algorithms, and delivered to memory. Where the memory is and what kind it is makes no difference. CF, SD, Firewire/USB to your laptop/ desktop, whatever. If you request JPEG, then you allow other camera/ scanner firmware/software to muck with it (before you get it), producing a printable compressed file, losing some data in the process.

RAW? You cannot scan RAW files or scan to RAW. Those are proprietary files that a Digital SLR creates and you use Adobe Camera Raw to open, adjust and then save them as JPEG or whatever file you want, except RAW.

Try scanning raw.
Less messing around. But really mainly good if you've kept your Photoshop chops up through the years. As scanner interfaces and software changes but
Photoshop is still Photoshop.
