	kallitype            The kallytipe (and similar: browprint, sepiaprint, van Dyke, silver-iron print, …) is a photographic printing process that has been used round the end of XIX century which has not to be confused neither with the calotype (talbotype) nor with collotype. For the kallitype, a sheet of paper is sensitized wetting it in a double solution of an iron salt first and in one of silver nitrate secondly (the usual photographic sensitizing salt). The sheet, set firmly in contact to a negative film and exposed to the U.V. light, 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 the time duration. The process was economic and simply feasible compared to others, but rather slow in respect to the new silver methods incoming at the epoch, with much shorter exposition times.
