To counter problems with very bright highlights

If the subject is too bright, the iris may close too much, leaving the overall image dark, or the highlights may be blown out. In such cases, setting the highlight clip function on reduces the luminance range, avoiding problems from the automatic iris correction.

In the AUTO IRIS page of the USER menu, set the CLIP HIGH LIGHT item to “ON”.
