Being a full-time huge fan/buddy of the guys over at the RAWexchange store, I often get asked to check out their new material. (Just to clear the air, no one is paying me to say any of this. I just love them and everything they put out ... like, for real. I DO get a cut of the sales if you happen to purchase something through one of my links, but that is besides the point. The RAWexchange Store really does just have top notch stuff that I ACTUALLY use in basically every image ... ok moving on.) Well friends, let me tell you that their newest endeavor to start selling in-depth tutorials is one of their best ideas yet. Stefan Kohler created a "Colors & Photoshop" tutorial that is two and a half hours jam-packed with everything you could ever hope to know about colors and how/why they work the way they do in Photoshop.
