Which type of radiation is primarily used in photography?

In photography, visible light is the primary type of radiation used to capture images. The camera's sensor or film responds to the wavelengths of visible light, which ranges from approximately 400 to 700 nanometers. When light enters the camera, it interacts with the sensor or film, resulting in the formation of images based on the intensity and colors of the light present in the scene being photographed.

While infrared radiation is used in some specialized photography applications, such as infrared photography, visible light is the standard and most widely employed type in conventional photography. Other forms of radiation, such as X-rays and microwaves, do not interact with photographic film or sensors in a way that produces recognizable images for typical photography tasks.
