Hi. I'm trying to work out if Nikon mean 12-bit compression, or 12 bit as in 4096 levels per RGB channel per pixel. If they mean compression, then what is the bit depth of the Nikon D40? And what do they actually mean behind the '12-bit compression'? It's just that of course 3x12bit would be 36bit which I'm not sure is even fully useable in photoshop, last time I checked photoshop went up to 32 bit editing. Thanks for any info. Dan.
