Part 1 of a 4-part series on STAGE LIGHTING, which will be posted every other week.
(Tip: Even if you don’t have an extensive stage lighting system in your theatre, your vocational students will probably work with them in college or in the real world, so teaching these enlightening tips is always a good idea!)
IN 1932 Stanley McCandless published a book titled “A Method of Lighting the Stage”. Notice he didn’t say “the”, but just “a”. However, for many decades this has actually been “the” standard method taught in schools and used in the industry, and is still “the” best starting point for learning about stage lighting.
McCandless determined that there are four properties of light that can be manipulated to create mood and location, or to draw the audience’s attention. The Four Properties of Light are:
Intensity – how bright the light is.
Color – rudimentary examples include blue or lavender for nighttime, green for a forest.
Distribution – the angle the light comes from, and also whether the focus is diffused or sharp.
Movement – this originally referred to “cuing”, which is when the intensity changes either up or down, or the other three properties change from one look to another. This has also begun to refer to actual movement, because “recently” (meaning the past three decades) we now have actual moving lights.
In order to achieve optimal manipulation of these four properties McCandless developed a layout we call the Light Plot. A Light Plot can be designed from scratch for a specific show, or a Rep Plot can be designed to accommodate multiple types of events. In the high school theatre setting, there is usually very little time – or money – to completely re-design (and re-hang, re-focus, and re-cue) a Light Plot from scratch for each event, so a Rep Plot makes much more sense as it can be easily adjusted to provide lighting for any event from class meetings, speeches, variety shows, band and choir concerts to plays, musicals and dance recitals.
Following is a very basic diagram and explanation of the McCandless layout...
