Thanks George for all the handy tips. I usually shoot raw with auto white balance and work with acr/photoshop cs4. I don't shoot a large number of images due to lack of free time away from work during daylight hours so I guess I haven't noticed it slowing me down but I'm sure you're right about that. I'll try the raw + jpeg option to see how it works. I typically save my finals as jpegs to an external drive and burn my raw files to dvd. I'll definitely try your ideas about tiff and psd files. Thanks again.
