For Example you see a picture of a negative 6x4.5 sm., from which the work “Charade” was printed. Usually we work with a negative of 35 mm. film, which allows us to receive more expressive figures. Besides that on the small area it’s easier to control chemical reactions. The work with color on the negative has its own specification – in order to get the needed, not accidental, color specter you must know the opposite colors very well. For instance, the use of brown dyers on the negatives will generate dark blue gamma on the print, as well as to get red shades on the negative you need to work with green colors.
