Cyanotype is a photographic printing process that produces a cyan-blue print. Engineers used the process well into the 20th century as a simple and low-cost process to produce copies of drawings, referred to as blueprints. The process uses two chemicals: ammonium iron(III) citrate and potassium ferrycyanide.
Solarisation (or solarization) is a phenomenon in photography in which the image recorded on a negative or on a photographic print is wholly or partially reversed in tone. Dark areas appear light or light areas appear dark.
In short, the mechanism is due to halogen ions released within the halide grain by exposure diffusing to the grain surface in amounts sufficient to destroy the latent image.
A photogram is a photographic image made without a camera by placing objects directly onto the surface of a light-sensitive material such as photographic paper and then exposing it to light. The usual result is a negative shadow image that shows variations in tone that depends upon the transparency of the objects used. Areas of the paper that have received no light appear white; those exposed through transparent or semi-transparent objects appear grey.

1. Gif- a lossless format for image files that supports both animated and static images.
2. Zoopraxiscope- The zoopraxiscope was invented by British photographer Eadweard Muybridge in 1879. It was a primitive version of later motion picture devices which worked by showing a sequence of still photographs in rapid succession.
3. Kinetoscope- The Kinetoscope is an early motion picture exhibition device. It was designed for films to be viewed by one individual at a time through a peephole viewer window at the top of the device.
4. Chronophotography- Chronophotography is an old technique which captures some frames of a movement, combined into a single image.
