A photogram is a photographic image created without the use of a camera or lens. Objects are placed directly onto a sheet of photographic paper, which is then exposed to light. Areas where the objects block the light remain unexposed and appear lighter in tone, while the exposed areas darken. This technique produces unique, shadow-like images that capture the shapes and translucency of the objects used.
Cibachrome, also known as Ilfochrome, is a specific type of reversal (R-type) color paper and printing process renowned for producing vibrant and long-lasting prints. This process is unique because it prints directly from a positive image (such as a slide or transparency), resulting in color saturation that matches the original image and often provides greater…
Silver Salts Silver salts are light-sensitive chemical compounds used in photography. When exposed to light—either in a camera (for film and negatives) or in the darkroom (for photographic papers)—the silver salts darken in proportion to the amount of light reflected from the subject, creating an image. Silver Bromide Print Silver bromide prints are a type…
A photographic collage is a single image constructed from multiple photographic prints. This artistic technique involves combining several individual photographs to create a cohesive and often visually striking composition. The resulting collage can convey complex narratives or themes, blending various elements into a unified artwork.
Digital colour coupler prints, also known as chromogenic prints, are similar to standard C-type prints. In this process, silver salts in the photographic paper ‘couple’ with colored dyes during development, rather than being replaced by them. The resulting images are comparable to standard C-type prints but have the advantage of utilizing the highly light-sensitive silver…
The autochrome is an early color photography process patented on December 17, 1903, by Auguste and Louis Lumière. Before its commercialization in 1907, the Lumière brothers shared the autochrome technique with select photographers, such as Sergey Prokudin-Gorsky. The process was widely used from 1907 until about 1932, notably for many photographs of the First World…
Pigment-based inks are composed of tiny granules of pigment powder that do not dissolve completely in solution, unlike dye-based inks. This characteristic allows pigment-based inks to leave particles of pure color bonded to the surface of the paper. As a result, the images printed with these inks appear rich and physical, with densely saturated colors….
