via flickr: If you recorded your show with three different mics that recorded treble, mid, and bass separately, then mixed them together in post, you'd have the equivalent of what digital cameras do with red, green, and blue. If one channel clips before the other channels do (such as your red has done here) you have a color shift because one channel is pegged while the others are still varying.

via flickr: that could possibly be the best analogy for audio guy i have ever read. i totally get it! if i had been looking at the color spectrum i would have seen red clipping. how do you stop something like that? or better how can it be lessened in post?

via flickr: You can partially fix in post by using the curves tool to bring the gamma down a little bit, and adjusting the red curve to try to round out the clipping. But of course, once you clip the channel, the info is just gone and there's no way to accurately get it back.

Your cam probably lets you see RGB histograms, so when you shoot, you should check to make sure no particular channel is getting clipped. In practice, it's almost always the red channel you have to watch out for.
