1. Anything that reduces the time and effort of getting an image into whatever the final format I am looking for is critical. By the nature of digital I take so many more shots that I did with film, so it is vitally important to be able to do this. Screwing about with finding the 'right' color is not my idea of fun.
This is probably a subject for a whole other thread but I'll bring it up anyway.
How are you shooting and storing your images for your commercial stock business? Are you shooting in raw and converting to TIFF or JPEG? Or, are you shooting JPEG right out of the camera. What format are your clients looking for?
