Exactly, 'RAW' usually means it is pretty close to the internal format that is used either by the hardware (as in DSLR's) or some software like photoshop. AFAIK, there is no software yet that will convert some generic image file like TIFF or JPG to one of the RAW formats normally used by cameras. It would be hard to come up with real advantages for doing that apart from trying to fake someting :-) The advantage in using some kind of RAW format as output for digital cameras is that LESS processing is required in the camera which could make it faster, and also that the needed conversion with regard to color and de-mosaic can be done on a powerful system, and could be retried to get the optimal conversion. The conversion usually LOOSES information in this step, so if you just have a single opportunity (in camera) it has to be perfect each time ... >Ah, okay. > >In Photoshop 7, 16-bit files have three save options: PSD, TIFF, RAW. >I've never bothered with that RAW since TIFF was always industry >standard. The 'RAW' used there is probably a format that closely matches the memory-structures used by photoshop internally.
