I have found the largest JPEG option to be the best. The RAW files have not been as easy to work with on my D1X. You have to be pretty careful about WB settings in JPEG, but otherwise yeilds great results. My only caution is only JPEG once. Shooting in JPEG is not problem, multiple sessions in photoshop saved each time as a JPEG looses information with each compression. Save your original, then save manipulations as TIFF files. Best wishes!
