@Carlos: I use the Auto mode, A for amateur.
The question of decision making process in photography is interesting. Lets say do you agree that the unsung heroes who created Kodachrome should be given credit in every masterpiece that was shot using Kodachrome? Do you think every Salgado book should give credit to all the people behind Tri-X in Kodak? Because it was not photographers who came with these famous films, it was some unsung quiet dudes working in complete obscurity that created those films.
Similarly the modern DSLR is an extremely complicated computer that is made to be used even by a complete computer illiterate person, but lets say if that illiterate person turns out to be a great photographer and wins an award or something, should he give credit to the engineers in the company where his camera was made? And these examples can go on ad nauseum.
The point I'm trying to make is that every decision about the technology that a photographer needs to make a photograph with is already decided by someone else. A photographer's decision is simply an act of pointing at something and clicking. even what happens in post processing is already decided by someone else.
So, the notion of decision making is very tricky, and its incredibly arrogant of a photographer to think of himself as the sole creator of a picture. And those who think using their teeth is a better method to open a knot rather than their fingers are simply fooling themselves, and taking false pride at something that is after all the result of work by engineers spending thousand of hours on research.
A photographer uses a lot of technology and the hard work of others to point at a subject and take a picture. How he uses all that technology and effort of others to make a picture is his part. Otherwise, to be a true photographer one should design and make one's own camera, post processing software, printing machine and ink.
