Bromoils evolved from the traditional black & white photograph where the silver particles in the image are replaced by oil based printing inks. This process creates subtle artistic images. The painterly nature of the bromoil makes every image unique – in either monotone or numerous colours. BROMOIL HISTORY The (more…)
ABOUT NEW CHRYSOTYPE PRINTING The New Chrysotype process has tonal and surface qualities and permanence like Platinotype-Palladiotype, but the added feature of beautifully muted colours, controlled by the chemistry and physics of the process. The photographic artist should find here a whole new palette of non-literal colour to (more…)
ABOUT THE SALT PRINT: This is a simple process with a number of challenges to master. Salt prints are created by coating paper in a solution of sodium chloride (common salt) followed by a silver nitrate solution to create silver chloride. Exposing to UV light changes the silver chloride to image making metallic silver. Salt (more…)
ABOUT THE ALBUMEN PRINT: Albumen is a salted paper print with an albumen binder. Albumen from egg whites holding the photographic chemicals to the paper. Cotton paper is first coated with a salted albumen solution, followed by a silver nitrate solution to form light-sensitive paper. Exposure to light changes the silver chloride to image forming (more…)
ABOUT PLATINIUM AND PALLADIUM PRINTING: Printing in platinum and palladium is acknowledged as the summit of alternative processes – images formed in totally permanent ‘noble’ metal, exquisitely graduated in tones of neutral grey or warm sepia, with a beguiling luminosity in the high values. This modernized version provides a ‘print-out’ image, having some advantages in (more…)

ABOUT CARBON PRINTING The carbon printing process uses colour pigments producing one of the the most permanent coloured photographs. The use of pigment allows any colour photograph on almost any surface. The beautiful tonal scale resolves fine detail. It relies upon the ability of sensitized gelatin when exposed to U V light becoming insoluble in (more…)
Four Colour Carbon ABOUT THE CARBON PROCESS The carbon process, initially a black-and-white process using lampblack (carbon black), was invented by Alphonse Poitevin in 1855. The process was later adapted to color, through the use of pigments, by Louis Arthur Ducos du Hauron in 1868. Carbon photographs were the preferred process of the top echelon (more…)
ABOUT TINTYPES Tintypes or ferrotypes are positive images created by a wet plate process. The black “tin” plate is coated with collodion, exposed in a large format camera and processed in a darkroom before the plate is dry. HISTORY OF TINTYPES The tintype was (more…)
ABOUT AMBROTYPES Ambrotypes are under exposed negatives that appear as positive photograph. The black or clear glass plate is coated with collodion with added salts, light sensitivity is created by “dipping” coated plate into silver nitrate bath. The plate is exposed in camera and processed in a darkroom before the plate is dry. Each photograph is unique – “one (more…)
