The clipping point means the range where the output level changes the same amount with respect to the changes in photographic exposure. At Sekonic, the range from the Middle Tone in the highlight direction is called the "clipping point (+)", and the range in the shadow direction is called "clipping point (-)" . You can set 0 EV to +10 EV for clipping point (+) and -10 EV to 0 EV for clipping point (-).
