What sorted camera for me was a shed load more light.
Basically, put on shutter control at 1/100 and 800/400 ISO (depending on how good your camera is). Then pop on a tripod and bracket exposure by 1/3 stop, and take with a timer (or ideally an IR remote - the best investment I ever made). Pick the best one and repeat. Then take lots at that setting while waving card under the lights so the fishes shoal. Sorted.
If that doesn't work, you need more light, basically.
