Glossary

Albumen paper - was introduced by L.D. Blanquart -Evrard in 1850. The process consists of coating a light sensitive paper, usually 100% cotton, with a mixture of salted egg-white (albumen) and dried. Once dried the paper will have a slightly glossy surface. Then the paper is sensitized with a solution of silver nitrate. Albumen paper was widely used since it was cheap, easy to use and could also be stored for later use.

Aperture - is one of the mechanisms that control the amount of light passing through the lens to the sensor. It is calculated in F-stops. When light levels are high the hole is small (ex. F16) to restrict the amount of light hitting the sensor. On the other hand when light is low a wide aperture (ex. F2.8) is needed in order to allow more light entering the camera.

Autochrome -  was the first practical process for producing colour photographs, which was invented by Auguste and Louis Lumiere. They patented it in 1904.

The process involved applying a layer of fine mixture of dyed potato starch to a glass plate and after inflicting the whole plate to massive pressure. The plate is then coated with a light sensitive silver bromide emulsion. The slide is exposed in the camera and the result is a glass transparency.

Calotype – also known as (Talbotype) was the photographic technique invented by British chemist/photographer William Henry Fox Talbot. It was a process for creating photographic negatives, from which numerous prints could be duplicated.The process involved using the best quality paper which was first treated with silver iodide and potassium iodide. After drying and immediately before use, the paper was then soaked in a ‘solution consisting of silver nitrate, acetic acid and gallic acid crystals.’ The paper would be ready to be exposed in the camera. After exposure, the image was developed by washing in gallo-nitrate of silver, rinsed and fixed in hypo, thoroughly washed again and dried.The translucency of the Calotypes could be improved by waxing the back of the paper. More positive images could be duplicated by repeating the same process.

Camera Obscura - which also means "dark room", is an optical equipment where images of external objects are projected through a lens and focused on a screen with the help of the mirror placed at a 45% angle. It was often used by artists to make sketches and drawings.

Cyanotype - also known by the term blueprint process was invented by Sir John F. Herschel in 1842. It was the first technology using a solution of iron compounds instead of silver. The simple process consists of mixing potassium ferricyanide and Ferric ammonium citrate (green) with water separately and then blend them together in equal parts.

Cyanotype can be printed on an absorbent material such as paper and textiles while coated with the solution and dried in the dark. It is printed by using Uv light such as the sun, a light box or a uv lamp. 

After the exposure the photograph is finished by rinsing it in water and dried.

Dadaism A nihilistic, anti-war art movement (1916-1923) that began in Zürich and Switzerland, then flourished in Europe early in the 20th century; based on irrationality and denial of the accepted laws of beauty by producing works marked by nonsense, travesty, and incongruity. Dada was anti-art.

The dadaists developed some art techniques such as collages, assemblages (3d collages), photomontages, and ready-mades.

Heliography - is the process invented by Joseph Niephore Niepce in 1826. The first permanent photograph was taken from the Window in Le Gras. He coated a pewter plate with bitumen of Judea, which hardens when exposed to light. After about 8 hour exposure in the camera obscura, the plate was washed with oil of lavender. The light areas were defined by 'bitumen while the shades by bare metal'. (The Focal Encyclopaedia of Photography page 736).

Kinetoscope - is an instrument invented by Thomas A Edison and his employee William Dickson, for showing moving pictures without sound. It consists of an upright wooden cabinet where a strip of film passes between  a magnifying glass and an electronic lamp. The viewer could see the moving picture from a peephole in the top of the cabinet.

Rayograph is an image produced without a camera by placing an flat or three-dimensional objects on photosensitive paper and exposing it to light. It can be exposed to several light times until the desired effect is obtained. It is actually called a photogram, and existed since first days of photography, but was more developed by Man Ray during his experimentation with photography in 1921. He renamed it Rayograph.

Texture  emphases the features and details in a surface or a partial object, such as the weave of a fabric.The three important features in order to create an interesting composition are contrast, curves, and patterns. Texture gives character to the object and also a three dimensional look especially with the use of hard lighting from the side.
