Note the image ranges from Blue Green to Black

  Green tint

  Rose tint

  Straw tint

  Yellow Tint

  Two shades of Amber tint.  The title is slightly darker than the picture

  Pale yellow tint

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.

This is a piece of unprocessed pre-tinted orange base. The picture on the left is the emulsion side, the one on it's right is the base side showing the orange tinting.

To the right of these is a piece of yellow pre-tinted stock where the sound track area has not been tinted. The picture is of the base side of the film. To the right of that is a piece of green tinted stock also a piece that has been partly fixed to show the tint and below a piece of blue 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 and toning.

 'All the Colours of The World' produced by the Gamma Group and published by Edizioni Diabasis, 1998 contains illustrations from Agfa, Gevaert and Pathe.

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.

Copper Toning

The image ranges from Clear to Brown.  Actually the clear areas are also slightly coloured.  It is very difficult to keep the clear areas clear when toning.

    Iron toning                     Dascolor

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.
