“KNEE” Function

When aligning brightness level to the person in front of a high luminance background during shooting, the background will blurred with white. In this case, use the knee function to obtain a clear background.

It will be effective to make use of this function under the following circumstances.

●When shooting a person indoors and view outside the window at the same time

●When shooting a person under a shade on a fine day

●When shooting a high-contrast scene

Caution

If the high-luminance section of a fast-moving body such as a car under sunlight is shot, the knee function may cause brightness of the entire screen to change according to the motion of the object. In this case, set the “KNEE” item to “MANUAL” during shooting.
