[QUOTE="Steve B, post: 249255, member: 15754"] Yes and no. The light drop off is dependent on the starting light source to subject distance and the amount of change. Think about in a studio environment. Say you had your strobes 20ft away from the subject (big studio :-) ) if you move the subject two inches away from the light source the intensity will decrease by a small amount. But if you move the subject twice as far (40 ft) the intensity will be 1/4. It doesn't matter how far the camera is from the subject it only matters how far the light source is from the subject. In your test environment I am sure that the reflective white ceiling is having an effect on your results. Paint your ceiling, walls, and floor a flat black and try it again. :-) [/QUOTE]
