ABSTRACT

The advantages of variable contrast paper over graded paper have been discussed in previous chapters. The most important benefit is the ability to get all paper grades from a single sheet of paper, which provides creative controls otherwise not available. All this is possible, because variable contrast (VC) papers are coated with a mixture of separate emulsions, which have different sensitivities to blue and green light. By varying the ratio of the blue to green light exposure, any intermediate paper contrast can be achieved.
