When you shoot film, since you don't have a darkroom, do you throw away the negatives? My strategy was to always shoot in raw format. When I first got my DSLR, I just ran the raw files through a very basic raw conversion and concentrated on getting the most out of the camera. I then picked up some basic processing skills, and started working on learning to shoot the pictures to take advantage of the post processing environment. One advantage is that photos I took before I got lightroom three, can now benefit from the improved noise reduction available in lightroom 3 that wasn't available in lightroom 2. If I get even better tools in the future, I have the option of going back and processing them again. -- Larry Colen [email protected] sent from i4est -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
