Not eggsactly what you are asking about, but worth considering -
"“How do I take good photographs?” A friend asked me this on a climb not long ago. I asked him where his camera was, and he replied that it was in his pack. I asked him where mine was, and he pointed to where it was hanging off my shoulder strap. Lifting the camera to my face, I took a shot of him quizzically pointing at me, with the mountains arrayed in the background."
