1. A method for creating a plurality of baseline images of a space, the method comprising:
turning on a first lighting load in the space;
recording a first image of the space when the first lighting load is turned on;
storing the first image as a first baseline image for determining a contribution of the first lighting load to a lighting level in the space and how to control the first lighting load to control the lighting level based on the contribution of the first lighting load;
turning off the first lighting load;
turning on a second lighting load in the space after the first lighting load is turned off;
recording a second image of the space when the second lighting load is turned on; and
storing the second image as a second baseline image for determining a contribution of the second lighting load to the lighting level in the space and how to control the second lighting load to control the lighting level based on the contribution of the second lighting load.
