Why not simply use manual mode, whether you are using a tripod or hand held, it dosn't take long to get the hang of it, set shutter speed at 1/8sec at f4 with auto ISO to max at 3200 and see how you go for a starting point ,thats hand held, tripod ,go for longer exposures, then it wont matter what file sizes you pick.
