This photo of my photoalbum was taken in Tokyo.

The pinhole camera model describes the mathematical relationship between the coordinates of a 3D point and its projection onto the image plane of an ideal pinhole camera. This means that the model does not include, for example, geometric distortions of the types that are caused by lenses. It also does not take into account that most practical cameras have only discrete image coordinates. It is considered the ideal model of camera.

Overcoming shyness. Shyness and street photography seem to be mutually exclusive. However, most successful street photographers have started as shy photographers. Some photography instructors have recommended starting out by trying to be stealthy and using long lenses. Others suggest bypassing such crutches, instead leaping into the "deep end of the pool" and heading into the street with a normal or wide-angle lens. Sometimes using an extreme wide angle lens and appearing to be pointing the camera somewhere other than at the subject can help, but at the expense of direct involvement with the action. Other photographers stand at one spot on the street and wait for the proper subject to appear. This was done most notably by Philip-Lorca diCorcia, who actually has set up elaborate strobe rigs on street corners in advance of unknown action. Magnum Photos photographer Bruce Gilden's famously-direct method of just suddenly walking up to people in New York at close range with a powerful strobe shows that the demeanor of the photographer before and after the moment of exposure is a key element to interaction on the street, with the latter more important. Gilden has claimed to have never suffered an aggressive response.
