Hi guys, I've recently went to fren's wedding dinner and shot a few photos. Do you guys mind telling me what f/stop to use when shooting 2-3 persons standing in a row and 5 or more persons standing in 2 rows? Sometimes, i shot in f/4 but it seems that some people is still OOF. But when i shot in f/8, tt is too dark. lol.. and my flash couldn't bounce it as the ceiling is too high. I could have aim the flash straight at them, but what's the minimum f/stop i need to shoot those people? Thanks.
