about us







Gumgraphies don't give proof of documentary evidence which is characteristic of conventional photography. By using formal means as among others colour, texture or materiality a subjective image of reality is created. At the same time the onlooker will be inspired by these formal elements to have associations. Gumgraphy is a photography process at which the positive material itself is coated (contact printed). The light-sensitive layer consists of gum arabic, chromate salt and pigments. Among others drawing paper or material can be used as base material. This will first prepared by applying a mixture of gelatin which causes the pigments to remain on the base material surface rather than sinking in. The coated material will be exposed in daylight or ultraviolet light under a samesize negative.   >>
