I think the best and most enduring photographers probably came at it from an emotional level first. They had a concept or emotion they wanted to convey. Once they found they couldn't get what they wanted they found they must master the craft. Thus becoming technicians. As MAS said above technical considerations become minimal, especiallyl once they are mastered, and who is to argue he hasn't mastered his craft. Once they are mastered then the photographer can concentrate on his artistic journey.
If the artist wants to do something new and requires a different set of skills then he/she must then again emerse themselves in the technical aspects again until they get what they want.
The problem is when people get so caught up in the technical aspects that it becomes an end in itself. What results are technically perfect, boring photographs that say nothing and only evoke feelings in the photographer themselves. If this is all that interests them, then all the power to them. Nothing wrong with that. But if they truely want to communicate something to a non-photographer, then they should probably spend as much time studying master painters as they do studying Dmax curves and developer formulas.
