The grader is one of the most expensive men in a laboratory - they are paid well but also influence both the quality and the output more than any other individual [except perhaps the Technical Manager]. Rarely has any laboratory formally trained their graders, although the following Colour Grader Training programme devised by Kodak at their Motion Picture Training School at Hemel Hempstead about 1968, has been available as a published document since then. The method was devised to teach a grader to use the additive lamp house for colour grading. The student is shown a still single frame projected on a screen and makes a correction based on their judgement. The Instructor then projects the corrected image. The images can be displayed by a projector or on a light box [with the help of a magnifier, as many graders work]
The laboratory can make as many 91 print sequences as they have suitable and varied negatives. Some of the sets should be of conventional scenes, long, medium and close-up, but a proportion of night scene, day-for- night scenes and other unconventional scenes should be included.
