A photograph (often just photo) is a representation of an image created by collecting and focusing electromagnetic radiation. The most common photographs are those created of visible wavelengths, producing permanent records of what the human eye can see.

A photograph is taken using photographic film loaded into a traditional film camera or using a digital camera. Most photographs are produced with a two-step process. In the two-step process, the film holds a negative image (colors and lights/darks are inverted), which is then transferred onto photographic paper as a positive image.
