Photography refers to the process or practice of creating a photograph – an image produced by the action of light on a light-sensitive material
A photograph can be either a positive or negative image and made using one of many processes.
Most photographs are created using a camera, which uses a lens to focus the scene’s visible wavelengths of light into a reproduction of what the human eye would see.
Non-digital photographs are produced using a two-step chemical process: light-sensitive film captures a negative image (colors and lights/darks are inverted) from which a positive image can be made by transferring the negative onto photographic paper (printing).
The advent of digital photography has led to the rise of digital prints. These prints are created from stored graphic formats such as JPEG, TIFF, and RAW. These can then be printed out using printers including inkjet printers, dye-sublimation printer, laser printers, and thermal printers. Inkjet prints are sometimes called giclée.
The process and practice of creating photographs is called photography. The word photograph was coined in 1839 by Sir John Herschel and is based on the Greek word phos, meaning light, and graphê, meaning drawing – so drawing with light.
