From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I use XSane for scanning photos and I get good results. It has plenty of options and auto-names files like you said. I'm not sure what Descreening and Backlight Correction are for, though.
Thanks for replying :)
It looks like it does pretty much everything I need, but I'm having some trouble getting the colours correct. I'm getting a slight purple tinge on the sample photo I'm using. It might just be that I need to learn how to do it through XSane, so I'm having a play with the settings.
Descreening helps to get rid of the old newspaper effect that newspapers and some old documents had. It's not usually needed for photos, but I've got some clippings from newspapers, and some very old documents with the effect.
Backlight Correction basically just brings up the brightness in a photo, but rather than just cranking up the exposure or brightness, it seems to do the equivalent of bringing the detail from shadows in Photoshop. It's not great, but now and then it does a good enough job that I don't have to open a photo editor.
Maybe the levels slider? If you place the black point pointer further to the left shoulder of the curve, the shadows won't be as dark.
I've tried that, but it adjusts the whole image rather than focusing on the shadows. It might just be something I'm getting wrong, but in the Epson scan software, it seems to only affect the shadows and dark areas. More often than not though, it affects the whole photo and screws it up, but when it does get it right, it's great.
Because it screws it up so often, I can live without it, but I'm still struggling with the colour cast.
