Since this one can have many interpretations, I will talk about street photography.
It is not that I go wandering around taking random pictures. Well, on a second thought, it is something like that but I have to be very discreet.
So, the way of taking pictures like that is not standing just in front of people with your camera pointing at them. What I do is that I place my camera on my hip, facing to a different direction that my camera is pointing at, with an already medium focus distance set and then I click the button not after listening the shoot-ready sound the camera makes. Later, I will have to do some post-processing since sometimes photographs are out of focus or pointing to the floor or maybe too high.
