| Five kallitype prints gold toned - in portfolio - on watercolour Arches paper 1989 Size 28 x 38 cm ALIBI: latin entry, means 'elsewhere', 'in another place' The kallytipe (and similar: browprint, sepiaprint, van Dyke, silver-iron print, ...) is a photographic printing process used round the end of XIX century, not to be confused neither with the calotype (talbotype) nor with collotype. For the kallitype, the sensitizer is a double solution of an iron salt and silver nitrate. It produces a clear image that needs only of beeing fixed for giving a final sepia colour copy. The copy was often gold toned to improve the colouring (bluish) and time stability. The process was simply feasible compared to others, but rather slow in respect to the new silver methods incoming at the epoch, with much shorter exposition times. |
