I filmed a couple of bands last night...hayseed dixie and their support act.I have watched the shows back and the lighting leaves band members looking like white objects( no real detail) when i zoom out,is this oversaturation or whatever it is called??.Also filming in low light causes the picture to look grainy,not awful and unwatchable,but a grainy appearance.Is there anyway to reduce either of these problems,any tips will be greatly appreciated.
