Watercolour paint used in photographic hand-colouring consists of four ingredients: pigments (natural or synthetic), a binder (traditionally arabic gum), additives to improve plasticity (such as glycerine), and a solvent to dilute the paint (i.e. water) that evaporates when the paint dries. The paint is typically applied to prints using a soft ...
Mucilage mixed with water has been used as a glue, especially for bonding paper items such as labels, postage stamps, and envelope flaps. [7] Differing types and varying strengths of mucilage can also be used for other adhesive applications, including gluing labels to metal cans, wood to china, and leather to pasteboard. [8]
From its inception in 1839, photographers had been using pigments to hand colour photographs. [1] The most common method used was the addition of colour to the finished daguerreotype, ambrotype or print. But by the 1850s there were two well-established processes based on using photographs as the base layer over which pigments were applied.
While it is possible to print by hand using a roller or brayer, the best consistency in pressure and even distribution of ink is most effectively achieved on a mechanized press. The collotype printing process was used for volume mechanical printing before the introduction of simpler and cheaper offset lithography .
Agfacolor. Ap-41 process (pre-1978 Agfa color slides; 1978-1983 was a transition period when Agfa slowly changed their color slide films from AP-41 to E6); Anthotype; Autochrome Lumière, 1903
Media, or mediums, are the core types of material (or related other tools) used by an artist, composer, designer, etc. to create a work of art. [1] For example, a visual artist may broadly use the media of painting or sculpting, which themselves have more specific media within them, such as watercolor paints or marble.
Opalotype or opaltype is an early technique of photography. Opalotypes were printed on sheets of opaque, translucent white glass; early opalotypes were sometimes hand-tinted with colors to enhance their effect. The effect of opalotype has been compared "to watercolor or even pastel in its softer coloring and tender mood."
For example, Ansel Adams used darkroom exposure techniques to darken and lighten photographs. Other techniques include retouching using ink or paint, airbrushing, double exposure, piecing photos or negatives together in the darkroom, and scratching instant films. Software for digital image manipulation ranges from casual to professional skillsets.
