I'm currently working on a small tool that does essentially the same as PTLens, but on DNG files: * scan a folder of DNG files and for each: * identify the lens used, the focal length, the focus distance, the aperture * use (some of) these info to determine Adobe Camera Raw's Chromatic Aberration settings from some sort of lens database (user-definable) * set these correction values directly into each DNG file (so next time I open it I got the right correction automagically!) (and possibly do other things, like recover edges from raw, apply Author and copyright informations, extract the JPG preview image into a separate folder, start a custom PS action, and so on). Of course, for those who have ONLY top-notch lenses with NO C.A at all, this might not be really useful. To me it is ;-) What mostly annoys me today is that 3rd party lenses are not identified correctly (e.g my Sigma 18-125 is seen as a Pentax 28-80). In a better world I would have only Pentax lenses, but I'm in real life now :-( so I will need to setup some 'alias' function, where one can say "hell, I don't have a 28-80, let's say it's a 18-125", or "This 28-80 is used with f=125mm!!! (which shows in the EXIF!) It must be the 18-125". This tool will be protected by tens of patents filed in most countries in the world, with a street price somewhere between US$ 150 to US$ 200 (I'm willing to buy all pentax lenses) ;-) A discount price might be available to list members, under conditions ;-) Patrice
