As I was looking through my photos thinking about the things that catch my eye when I look at a photo and begin to edit. One of the things I always notice are the whites of the eyes. I NEVER EVER lighten them since that will make eyes look unrealistic, ghostly, zombie-ish, not good. But I do however look at the hue of the whites. Sometimes the resulting photographs appear with a very prominent blue hue. When my photo is warm but the whites are blue - that bugs me {personal opinion}. So here's what I do to fix this.

Here's the before photo (all editing complete except for the whites of the eyes being too cool for this image) :

Final Image: Small very subtle change but a more color cohesive photo.
