To improve the auto-focus of the COLLIDE-2 camcorders, the illumination
levels will be increased by increasing the reflectivity of internal surfaces
of the IBS. These pictures show the change in illumination in the
IBS from the COLLIDE-1 configuration, with paint on the target door, when
the door has no paint.
