Setting an appropriate iris
The last task to perform before shooting
is to set the iris of the camera. The iris
controls the amount of light entering the
camera which determines 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.
There may be times when you want to overexpose
an image, if you are shooting into a strong back-
light, for instance, but generally the rule applies:
minimize the zebra stripes.
IMPORTANT: Do not rely on how the image
"looks" in the LCD monitor to determine cor-
rect exposure because the LCD monitor shows
brightness inaccurately. Always use zebra
stripes.
