This tutorial won't work with all images, if it's too dark it will turn out too pixely and if it's too light it's just obnoxious, so screw around with the settings a little. What I found with most caps was it was either too red or too dark, and both of those can be fixed with a new color balance or curves layer. Or if the tutorial only works to a certain point do that, I learned from tutorials myself, it's all trial and error. In any case I'd love to see what you guys come up with, and if you have ask questions ask away!
