Somebody asked me why I usually look away when they take a picture of me in the mountains. And in fact I tell my partners not to look at the camera either. Not on every picture, but on the ones that really show the drama of the mountains around, it really is better to look away. It makes the picture better. Why?
I think it's because later, when you look at the picture, if the climber is not looking at "you," you can imagine yourself in the climbers position much easier. And then you place yourself in the scene. If you've been there before you'll get a great injection of nostalgia. If you want to go there, you'll get an energy boost to make the trip.
I look at the pictures that made me want to climb a certain route. If it has a person (usually it does...weird), then the person is always focused on the climbing.
Anyway, that was just a camera thought that occurred to me while wasting time on the web.
