The early immersive virtual reality rides were nothing but moving platforms with huge dome screens that filled the audience’s field of vision. The platforms pitched up and down, banked sideways, and rotated slightly to suggest movement. They never actually moved from a given point; all the suggestions of motion relied mainly on the retinal image with the head and body motion. With today’s addition of earth-shattering sound systems and a few environmental changes (such as water vapor and generated heat), the observer now feels immersed in this make-believe environment.

These meters can read only the light falling on a scene. Therefore, these types of light meters must be pointed in the direction of incoming light rather than reading the light reflected off the subject. Incident light meters are mostly handheld light meters with white diffusers. These diffusers can be either white domes or flat discs. The white domes “average” the amount of light shining on the scene; the flat discs are used to evaluate the individual light’s lighting ratio. Most commercial photographers and cinematographers use incident light meters because they can easily measure the various light levels falling on a scene without the subject influencing the reading.
