Here is a little information about using the Histogram that I believe will help some folks quickly evaluate problems and provide some with useful solutions. Please read what I have written carefully with attention to detail. Then if there is any misunderstanding of what I have presented and you have any questions I will do my best to answer with information that would help with your further understanding.

Note: This tutorial was originally based on use in PSCS2 and the Histograms there, however it is applicable to newer versions of CS and other programs. Some programs histograms are easier to read color cast from then others, for example it is easier to read them in PS or CS then LR2.
