Small holes, equivalent to the lens and aperture of a digital camera; Photographic paper, equivalent to photoreceptor; The opening time of the small hole is equivalent to the shutter speed; The distance from the front baffle where the small hole is located to the photographic paper is equivalent to the back focal length of the lens; The size and angle of the back focal length determine the shooting range of the scene. Using this principle to take pictures, it is necessary to accurately measure the focal length range before and after, determine the size of photographic paper, and determine the exposure time in advance. Nowadays, digital cameras are controlled by cameras in full automatic mode or scene mode or program automatic mode or priority mode, and photographers only have composition.
Nowadays, only a few photographers like pinhole photography. Probably pinhole photography is the most primitive, simple and authentic photography.
