I have a Sony a77ii with multiple lenses. I have been taking pictures since I was 10 with my first camera KODAK 127. I took 10,000 photos while in nam so I have a pretty good understanding of photography but am still looking to learn more. I have been a digital user for about 7 years and am just now getting to feel like I starting to understand some things. I have some questions if there is someone out there who can help me. I would like to know in the "QUALITY" section of my menu, it lists the following: RAW, RAW & jpeg, STD, FINE and Extra Fine. Could somebody please explain what each one means and which one should I be thinking about. Thanks.
