My point is simple, i don't write a question, but a thesys. If you don't know how other ask to you, tell at other, don't give a response like that one gave to me in the post "red garrish...", because i'm thinking that you don't know nothing of that you say. Well, i open this 2 post only for person that have study in a scholl of photography, had a good preparation on digital (better on programming PC) and have do many experiment with your camera and post processing software. that's all.
