2Setting an appropriate iris

The iris controls the amount of light entering the camera which deter- mines how bright the image will be (exposure of the image).

To set the iris appropriately, you must monitor the zebra stripes in the LCD monitor of the camera. Zebra stripes appear on areas of the image that are overexposed. In those areas, no detail is recorded because the light is too intense. A picture is properly exposed when there are no, or very few, zebra striped areas in the image.
