I used my iPhone 5 last night at a concert. How can I get optimal pictures under low light conditions? The flash works, but if I'm 10-15 ft away from the person/people I'm shooting the picture still looks very dark.
I'm afraid you will never get decent pictures from that kind of distance. The led flash isn't strong enough and even if you could manually slow the shutter speed the pictures would still be blurry if there was any movement.
You can try adjusting the photos post capture using iPhoto or similar. They will look grainy though
