    • Abstract:
      Photography is the process of forming images on surfaces sensitive to electromagnetic radiation. These surfaces are usually silver halide-based film or an electronic photosensor, and the radiation recorded is usually visible light, infrared radiation, ultraviolet radiation, or X-rays. Photography is an important technological tool for examining and documenting the natural and human-built world. For more than 150 years, photography has added vital knowledge to the physical, environmental, biological, medical, forensic, materials, and engineering sciences.
