Method and apparatus for composing flat lighting and correcting for lighting non-uniformity

摘要

A method and apparatus for composing uniform lighting and correcting for any remaining lighting non-uniformity. The method involves capturing a reference image utilizing a background sheet of uniformly reflective material. The reference image is processed and an exaggerated version of the reference image highlighting the hot and cold regions is displayed. The user modifies the lighting to compose the flattest lighting possible. A lighting calibration file is saved comprising a smoothed approximation of the light intensity of each pixel and the average of the pixels. The actual image is corrected for the remaining non-uniform lighting by utilizing the lighting calibration file.
