Iris
Iris is a continuous parameter controlled by DMX Channel 38. The iris is a device
with a variable circular opening that controls the beam diameter projected from the
selected fixture in a similar fashion that a camera's iris controls the amount of light
entering the camera. Table 4-12 describes the Iris settings.
