INTENSIFICATION

Usually the last act of desparation with underexposed and/or underdeveloped film. Bear in mind that it is not really possible to bring out detail that isn't there in the first place - all you can do is make what is there more printable, and bring it within range of a hard printing paper. It is best to check whether it is possible to print on the hardest paper, before resorting to chemical treatment. Staining and matting are a possible side-effect of the treatment, and it is essential that the material has been scrupulously washed, and that all dishes, mixers etc. are very clean.

Speedibrews CHROMIUM INTENSIFIER

Speedibrews SPEEDINTENSE

Somewhat greater increase in printing density than achievable with Chromium Intensifier. This works by converting the image silver into a red-coloured compound which prints with greater density to a blue-sensitive paper. The intensified negative may not be completely permanent, and may need later treatment.

Kodak SELENIUM TONER

Not marketed as an intensifier, but will have an intensifying effect on negatives, just as it does on prints. This is not a dramatic increase, and is more likely to be of the order of 1/2 grade increase. Grain may be made slightly finer.
