We always seem to be concern about getting the best image quality from each picture we shoot. Have read some good threads on how to take a shot, use the best lens, best camera, use a good tripod, lighting gear and even threads about which program to use for processing ones' shot. The one thing I haven't seen talked about or compared is a 8 bit vs 16 bit process file. Is there are difference between 8 to 16 bit files in image quality. If there is a difference between the two is it something that one can see in a 11x14 inch print? I ask because most PP programs and add on programs only do 8 bit, so what is the advantage if any to using 16 bit files over 8 bit files?
