That's kinda the whole point. If Leica plans to provide a "tweaked" file and call it RAW, that will be a "proprietary" definition. And an unfortunate one, IMO. As I said earlier, they could offer any in-camera JPEG tweaks in their RAW converter. How those of us who will not use their software will apply these adjustments remains a question. I'm still guessing that their in-camera adjustments won't actually amount to much if anything. They make good glass that should perform well (see R-D1 samples for evidence). All they're going to provide is a way to get the focal length and max. aperture into the EXIF. The rest will be that vaunted Solms "fairy dust." rs ______________________________________ www.robertschneider.com www.schneiderpix.com On Jun 7, 2006, at 11:07 AM, Adam Bridge wrote: > I'm thinking that even "RAW" images involve camera-level processing. > They aren't "pure".
