Looking through my pictures the other day my friend A asked me why I like taking photos of other people taking photos... To be honest it's never occurred to me before, but I guess I like their.. honesty..?
Since I started doing photography, I've realised how hard it is to get a candid shot, especially if your camera or lense (or both) is the size of a bazooka... As soon as a person hears the shutter go off they instantly stare at the camera or worse strike a pose.
When a photographer is taking a photo they are completely absorbed in the moment, trying to figure out the shutter speeds and apertures, capture the moment... most of the time they either dont notice you taking a photo of them or simply dont care...
