Adjustment layers can be great for this.
This is where the problem lies! Most of the pictures I take require massive amount of post production. It seems that they all have this "haze" over them, and I need to play with the contrast and saturation to get them right. I know the exposure is right (or at least close), and so is the white balance, but I can't for my life figure out why I need to adjust every image I capture.
I know that is particular picture has many other things wrong with it, like composition, perspective, and some hard shadows, but I only used it as an example of this "hazy picture" problem.
