Ok, it was a long time ago when I wanted to post a tutorial here. It was a sig tutorial at first, but these are everywhere, so after a massive amount of reiterations, I took it from a different angle and offer you a bit of a guide. This guide won't help the pro's too much (or at all), it's actually targeted at the beginner-intermediate part of community, those that have yet to experience the full power of Adobe Photoshop.
Well, I hope it's worth posting here. You never know what people don't know.
Oh and I do hope it's readable and easily understood. If not, go ahead and do tell me.
