I understand were you're coming from, yet the comparison doesn't really fly. It's easy to compose the photo without the mics yet impossible to 'crop' the sound pollution. The minor obstacle my mics pose is minuscule and doesn't negatively effect their end product. They move 6" to one side or the other and get perfect shots with my mics out of frame. The end result for me is a perfect recording of them taking endless photos.
The Indian music photographer clicked on the beat a total of 4 times in probably 500+ shots. I counted
It's mostly about awareness of the impact of our actions.. and respect for others. I go to great lengths to make my setups as visually unobtrusive as possible. Often people don't even know they are there, or that they are microphones.
Of course as recordists we become hyper aware of sound. Photographers become hyper aware of sightlines and lighting. I chuckle a bit when I constantly see photographers contort themselves and crawl to stay out of sightlines, only to start talking audibly to each other right in front of the stage.
I love great photography and a great visual performance, but with a few exceptions which I don't care much for anyway, musical performances are after all primarily auditory artforms. I often find myself wishing people would respect that (and each other) a little more, that's all.
As sound aware recordists, if any of you talk with the SLR manufacturers, please put in a plug for quieting the shutter/mirror in upcoming models. It could certainly be done I can't see any reason why not to. Rather, it would be a competitive advantage for shooting in all kinds of quiet situations beyond music photography.
