People with “lighting” in the title of their business cards can learn a lot from people with “video” in the title of their business cards. To make a certain color, like purple, a video projector can use “bit spreading” to project red for a fraction of a second and then blue. By controlling the duration of the red and blue projection, they can craft just the right color — and a better color than what might be possible with a luminaire…As video continues to gain in popularity in the performance arts, it’s imperative that the lighting community learns to select the right tools for the job and use them correctly.
