A pinhole camera has no lens. Light simply passes through a tiny hole.
There is no viewfinder so the composition must be approximated. Exposure times are lengthy: anywhere from several seconds to several hours. These long exposures can play with our preconceived notions of photography. Rather than a split second capture, passages of time are crammed onto a single frame. The flow of any movement doesn’t just freeze; it condenses on that lone frame.
Think cinematic crunch: 24 seconds on a frame instead of 24 frames per second.
