To reduce the influence to the auto iris due to shooting a high luminance subject
When shooting a high luminance subject, the auto iris closes too much and a white crush may occur on the image. In such a case, you can reduce the influence to the auto iris by setting CLIP HIGH LIGHT to ON on the AUTO IRIS page of the USER menu.
Since the level exceeding a certain level is clipped, the influence to the auto iris is reduced.
