I guess I'm looking at landscape photography as a different category. Perhaps because I'm looking at landscape photography as a craft reproducing something external whereas I would see music as pure art, exploring the soul's relationship with the world. I'm not sure why that is and I'm not saying it is the right way to look at these but I suppose to a large extent it's how I do see them.
I agree, but as might be obvious from my posts, it's possibly because you have artificially placed constraints on photography.
Photography is many things to many people and there is no reason to restrict photography to the external. Much much more so than the film days, modern cameras and software give you the tools to fully explore your souls' relationship with the world, but its hard work.
In the olden days, many people were satisfied with being able to fairly consistently produce sharp, well exposed and well processed prints of attractive subjects. The reason that I took to Ansel Adams, and the reason he changed my photography for ever, was that his mastery of, and obsession with, technique was driven by his need to produce images that captured how he "felt" about a subject. Although some dismiss him as only a master technician, everything he did was driven by his creative passion for the landscape and his need to capture how he felt about it.
For me, a much bigger problem than shock and awe software for photography is the belief that its easy, and I suspect its no accident that some of our best photographers (old and new), have been professional, or very serious amateur, musicians and have commented on how they brought the discipline of learning music into the discipline of learning their photography.
To go back to Ansel Adams. He had been a concert pianist before he turned full time photographer and was described by one music critic as a genius on the piano. Hs struggled to choose between music and photography, but also felt he couldn't split his creative energy between them both, and photography won.
As aside, he was also seriously criticised by many for having a very broad taste in photography and showing photographers in his gallery that didn't deserve to be called photographers because their photographs didn't fit into the large format technically perfect genre. Unfortunately I don't know who these photographers were, but more than one of his assistants have mentioned this when being interviewed.
