In fact the lens is a kind of telescope with which we can look at details, nearer or in a special manner. Photographers hide their faces behind their cameras, as if the camera was a disguise, pointing that telescope to things and people. And they get curious about what or how can they see thing through it.
I can't help thinking how creep it is. Specially street photographers wandering and look around at things and people through their lenses. And I have being called as "creep guy" once when photographing in the street. I don't get offended and if you are a photographers you shouldn't be offended aether. If you can't help stop looking at you viewfinder and waistlevel, you must be a damn creep.
