The first shot is made at the normal, metered exposure determined by a Sekonic L-758DR. The second shot is made at -3EV below the metered exposure and the third shot at +3EV above the metered exposure. Please refer to the illustrations on the next page.
To profile your camera and lens combinations, the Exposure Profile Target II is fully compatible with FREE Data Transfer Software and the L-758D, L-758DR, L-758Cine, L-478D, and L-478DR light meters. The result is total exposure accuracy.
