Tinting is carried out by dyeing the film emulsion or, in the past, by buying
film stock where the film base was coloured. All the major manufacturers
supplied a range of coloured base stocks.

tinted stock again with a piece that has been partly fixed. two more
samples of tinted base without the sound track tinted. Finally a selection
of pre-tinted stocks
Most stock manufacturers produced booklets that contained samples of tinting

Johnsons & Sons, Cross Street, Finsbury, London produced a sample book for
their Kinocolor Film Dyes.
When sound was introduced tinting caused problems with
the reproduction of the sound track; different colours caused changes to the
sound level, various methods were used to solve this problem. Kodak Ltd
patented the following method. Improvements in or

image ranges from Clear to Brown. Actually the clear areas are also
slightly coloured. It is very difficult to keep the clear areas clear
|Toning is carried out by
converting the black and white silver image to another, usually metallic,
element to change the colour.
Iron gives blue
Copper gives red to brown
Vanadium gives green
Uranium gives black to red
Selenium gives red-brown
Sulphide gives sepia.
It can also be achieved by replacing the silver image by a dye image
using a dye mordant. This gives an almost infinite range of colours
and was used in many of the early colour systems.
Film known as duplex film was made which had emulsion on both
sides. One side could be toned iron blue and the other side could be dye
toned orange. Dascolor used such a system. Dascolor: Duplex
film, One side toned Iron Blue, The other dye-toned Orange. The two colours
can be seen, the orange between the perfs and the blue green on the left
edge of the picture frame.
