Click on the photo to read the steps if it's too small. Notice how the photo on the left has a "gray haze"? At first the color seems great, until you look at the one on the right. I was standing in the same spot and the photos were taken only seconds apart, I just happened to have these two photos side by side on the screen when I thought "quick tutorial". This is what I do to bring true color out without really doing any editing effects. There aren't any overlays, minus the use of the original photograph, no brush work and no filters. These steps won't work on all photos in every scenario. Sometimes the use of "multiply" is too much, sometimes just using "overlay" mode isn't enough. You have to find what's going to work for the series of photos you are editing and go with it (see post below).
