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 DRY PLATE NEGATIVES When photographing In the field silver gelatin dry plate negative process can be more practical than the wet collodion process. Emulsion is poured on the glass plate and dried before taking it out in the field. The blue-sensitive emulsion gives the unique feel of 19th century photographs. They are also more sensitive to (more…)
PRINTING PHOTOGRAPHS ON FABRIC The workshop allows you to create photographs on natural fibres, cotton, linen and silk with a surprising clarity. It provides the following advantages over paper: Movement – especially silks Can be stretched onto a frame Wearable – cyanotype can (more…)
ABOUT NEW CYANOTYPE This process provides an image in stable Prussian blue pigment, from a ‘single-bottle’ sensitizer solution having a long shelf life. Requiring only a short UV exposure, it yields a superbly graduated tonal scale, on a matte paper surface, having a maximum density verging on black. The image (more…)
ABOUT CYANOTYPE This process requires no other chemicals, can be exposited in sunlight and developed simply in water. Cyanotypes provide a beautiful image in stable Prussian blue pigment. The image colour may be easily modified by a variety of toning agents. THE CANOTYPE HISTORY Sir John Herschel’s traditional cyanotype process, now practiced for 166 years, (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 LIQUID EMULSION This unique photographic printing process allows the artist the flexibility to hand coat silver gelatin emulsion on to a wide selection of surfaces including watercolour papers, timber, metals, fabric and glass. You can select the formula that suits your needs, making it from the raw (more…)
ABOUT WET PLATE NEGATIVE A glass plate is coated with collodion emulsion and sensitized, exposed in a large format camera and processed in the darkroom. The name wet plate is used as the solution must remain wet during the whole process. It loses its sensitivity to light when it is dry. The activity of preparing (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…)
