Make sure you have an external flash because once I was caught in a situation whereby taking a group photo the lighting was too dim in that room and end up using shutter speed 1/5 sec with the built-in flash. Good thing is that I have a tripod with me and the people stand quite still when I shoot. But the long exposure causes an unusual yellowish green tint from the lightings in which the built-in flash was too weak to correct it.
