I just purchased a 580 ex ii and 40" softbox for it. I've used it a few times on ETTL and definitely see an improvement with my images (especially sharpness). I would like to take advantage of more of the settings in the flash (assuming ETTL is like shooting on auto and probably a no-no according to you pros). I keep it directly to the right of my camera, would that be the best place when using only 1 light? I was wondering if anyone could give me any tips when using only 1 light or possibly any reading material/videos that would help me learn some of the settings on the flash. I've read the manual already
