If you're capturing RAW format, whether DNG or PEF, color space setting in the camera is irrelevant. The issue is a camera calibration issue. Nothing to do with the technology of the sensor, or everything depending upon how you want to look at it.. but the difference between CMOS and CCD is not relevant. The issue is that Lightroom does not have any calibration tables for the K7 as yet, AFAIK. So the thing to do is get the DNG Profile Editor, shoot a couple of controlled tests with a Macbeth Color Checker or equivalent, and create a good calibration profile for it. Install that as the default to use when processing K7 RAW files and your colors should be accurate. -- Godfrey www.gdgphoto.com www.flickr.com/photos/gdgphoto www.twitter.com/godfreydigiorgi -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
