See, rude. Would it not have been far more productive to clearly state which particular parts you were having difficulty with and request further clarification? I may even have been inclined to try to help. Instead, you come stomping onto my image thread, and make a sulky comment about how you couldn't get it. Well many people have found it very useful, several people have sent me polite notes asking for clarification, and I have provided such. Seriously, learn how to be polite and maybe you'll get a better response in the future - you don't deserve to understand, and I don't owe you a tutorial that speaks on your level. People asked for a tutorial that elaborated the techniques I use in the production of digital maps and I made one, out of generosity. End of story really. Your kind of response, simply makes the effort gone to in elaborating my technique feel like a waste - and frankly if you go around talking to people the way you have to me then I'm glad you didn't understand, as I don't really want you to benefit from my effort.
