One lure of taking photographs is that you get to hide behind a machine and safely observe the world. You get to look, without being seen. This was especially true in the early days of photography when photographic equipment was bulky and when exposing the film or plate required a dark area at the back of the camera. The dark area was created with a black hood. The experience of taking a picture meant getting under that black hood and entering another world from which you could watch the real world outside. The pleasure of it must have been like being in a pillow fort as a child. You are in a safe and hidden space, but you get to peer out through the cracks between the pillows in order to see what all the adults are doing.
