ABSTRACT:
A method and associated apparatus for calibrating a photographic media requiring only a minimal area of the media by producing a pattern of exposure patches utilizing the steps of forming an exposure area on a portion of unexposed photographic media as a plurality of abutted test patches wherein the width of all the test patches is substantially constant and the width is less than 100 .mu.m. Each test patch is then exposed at a substantially constant log illumination increment over the previous test patch.
