1. A method of recording an image from a cathode ray tube on photographic film using time modulation to control color in a vector film recorder comprising the steps of: defining a set of available colors for the image to be recorded wherein each color definition is a set of three numbers such that there is one number for each filter of a color filter wheel which is interposed between the cathode ray tube and the photographic film of the vector film recorder and which is controllable as to filter, wherein the color filter wheel has filters in the primary colors (red, blue, and green), whereby an electron beam of a predetermined and constant intensity repeatedly swept from one point on the cathode ray tube to a second point on the cathode ray tube at a predetermined constant speed for each filter according to the color definition in the vector film recorder results in a recorded image of the sweep in the defined color, converting the image to be recorded into a set of vectors, each vector having a single color definition from the set of available colors, wherein each vector is spatially defined by a first point on the cathode ray tube and a second point on the cathode ray tube and consists of the line between and including the two points, such that the sum of all vectors comprises the image to be recorded, recording the image to be recorded by generating sweeps on the cathode ray tube and setting the color filter wheel according to each vector in the set of vectors and the corresponding color definition for each vector in the vector film recorder.
