When shooting with the C100 indoors with a combination of fluorescent lighting and a bit of natural light, do you generally use Auto White Balance or custom white balance? And if so, how have you successfully custom white balanced? I find that the camera is great on the "sun" white balance preset for many situations where there's natural light, but I was just in a particular situation where there was very little natural light. I went back and forth between custom and auto, and in the end my footage is very soft and grainy, which has not happened before as I've almost always used the "sun" setting with no issue. Grateful for any thoughts or suggestions!
