Some insight from China:
The universities there tend to teach purely lighting design, with little or no hands-on experience until later in the program. The result is that the designs are unconstrained by the realities of production limits. This is not necessarily a bad thing. I see brilliant designs. The realities of limited fixture inventories, labor resources, power distribution, control consoles, and possible places to actually safely mount a fixture become the technicians challenge to solve and execute the design. This teaches the art of compromise to the design team.Designs that are constrained by the current realities are frequently uninspiring. Let the designers create a wonderful thing! Gradually, they will be jaded by the realities they face in executing them, but that is what time and experience teach.Learn about the color quality of light throughout the seasons, weather, and time-of-day. Understanding where the light comes from, how it is filtered, and what it should look like makes the design effort symbiotic to the story, not a layer on top of it. Take your students out to street scenes, cafes, courtyards, and living rooms at different times of day and seasons, have them stage a static scene and photograph it. Then go back into your light lab / black box / classroom and have them recreate the same exact scene and lighting. They will learn about color temperature, diffusion, color, lighting direction (angles), and shadows.
