Knowra Black-and-white photography Black-and-white photography Photography that records tones of light and dark without representing scene colors. It includes images made through monochrome capture or by removing color from a color photograph.
Silver halide : Light-sensitive compounds of silver and halogens used in photographic film and paper. In traditional black-and-white film, exposure changes silver halide crystals into a latent image.
Photographic exposure : The amount of light reaching a camera's recording medium during image capture. Exposure determines which scene tones retain detail in a monochrome negative or sensor file.
Camera obscura : An optical device that projects an image of an exterior scene through a small opening. It supplied an image-forming principle later combined with light-sensitive materials.
Documentary photography : Photography that records people, places, and events to present evidence or tell factual stories. Monochrome documentary work can emphasize gesture, texture, and social conditions.
Color photography : Photography that records and reproduces differences in the colors of a scene. It preserves hue information that black-and-white images omit.
Latent image : An invisible image formed when light alters photosensitive material before development. It is the hidden record of exposure that chemical development makes visible.
Dynamic range : The span between the lowest and highest signal a system can represent. It sets how much shadow and highlight detail can coexist in an image.
Niépce heliograph : An early photographic process developed by Joseph Nicéphore Niépce, producing images on light-sensitive bitumen. Its surviving view from a window is among the earliest permanent camera photographs.
Street photography : Candid photography of everyday life in public spaces. Monochrome can simplify busy urban scenes into patterns of light, shadow, and movement.
Sepia tone : A warm brown monochrome image tone, produced chemically or through digital processing. Sepia remains monochrome but departs from neutral black, gray, and white.
