Some of the Nikon cameras will save raw data too, although they save in 
a proprietary format called NEF (basically a 12-bit linear grayscale 
dump of the CCD before the pixels are filtered out into separate 
channels). Fortunately there are a few free or cheap NEF converters out 
on the web. I just learned there's a firmware update for the Coolpix 
5000 that will allow it to export NEF, but I haven't tried using yet.

Also, the auto-bracketing features on many digital cameras are handy 
for building multi-exposure HDR images, as they reduce misregistration 
due to camera shake.
