Pinto, I have a Canon D60 (and an Oly E10 and Canon G1--older but both use RAW--the Oly has its own RAW format), so can't comment on Nikon's. I have a number of photographer friends that have Nikons, mostly D1Xs, but I expect that this would apply to D100's also--I believe there is a software called Nikon Capture, but you have to purchase it. I'm guessing it is similar to Breezebrowser and Yarcplus for the Canons RAW format. I know about Bibble, but not enough to tell you anything. I'd recommend you try www.dpreview.com and check out the Nikon SLR forum and you would get straightforward infor from people using the software. Oly does have a plugin for PS for their RAW conversion--nice, but my preference is the 2 relatively inexpensive conversion apps for the Canon. Perhaps Bibble is similar--or you may prefer the Nikon Capture if you learn more about it. I've just picked up that information in passing when I occasionally read the Nikon SLR forum or from my Nikon friends. The important thing to know about RAW is that it is basically a negative--with no processing whatsoever and any other format will have some in camera processing.
