Abstract

A method of recording a color image on a monochrome photographic recording medium by the steps of separating the color image into three color components, one luminance component and two chrominance components; and recording the three color components on adjacent areas of the recording medium, the luminance component being recorded on a larger area than either of the two chrominance components.

Claims

1. A method of recording a color image on a monochrome photographic recording medium, comprising the steps of:

a. separating the color image into three color components, one luminance component and two chrominance components; and

b. recording the three color components on adjacent areas of the recording medium, the luminance component being recorded on a larger area than either of the two chrominance components.

2. The method of recording claimed in claim 1, wherein the combined recording areas fall within a standard image format.

3. The method of recording claimed in claim 1, further comprising the step of recording fiducial marks to indicate the location of the respective color components on the recording medium.

4. The method of recording claimed in claim 1, wherein the steps of separating the color image into color components and recording the color components is performed optically and the color components are red, green and blue, the green component being the luminance component.

5. The method of recording claimed in claim 1, wherein the step of separating the color image into color components is performed with a scanner to produce a digital color image having color components;

the step of recording the color components is performed with a digital film writer.

6. The method of recording claimed in claim 5, wherein the color components are L, a, b.
