[QUOTE="J-see, post: 425184, member: 31330"] Exposure has little to do with it. At least the exposure the cam indicates as correct. That's shot exposure. The problem is that your sensor receives very little light. ISO is post-sensor, it only amplifies the read-out but has no effect on the incoming light. I very often have black turn into purple and only and always during low light situations. Increasing ISO does nothing besides make it more visible. If it is clipping, you should never see it in shots when there is plenty of light. When you pull down the blacks it disappears and that's normal since it is a value close to the clipping point which is pure black. The higher the ISO you use, the more you'll see this kind of behavior. In the end, you're just upping the noise in those pixels. [/QUOTE]
