The first part of the DVD was goofy and supposed to be funny. It may have been done for Disney, and you may want to skip over it. After the band stops playing it gets very serious the rest of the way.
This isn't just a dry classroom lecture on light like some of the stuff you see on YouTube such as a professor giving a PowerPoint presentation. This is mostly video clips of many lab experiments during Dr. John Ott's career. You really must see some of his light experiments. In particular, the cellular changes due to different lighting.
I must admit my early research online into light and color left me a bit skeptical because it seemed somewhat like off-the-wall New Age ideas, but all that changed once I saw what happens to your cells. I don't know how you can argue with what you see under a microscope.
Ott notes at one point that some of his health discoveries were only discovered by time-lapse photography, and you would not be able to make the discoveries without time-lapse photography.
Many of the early video clips deal with how different flowers respond to different colors of light. This is all quite colorful and beautiful, and interesting, but somewhat irrelevant to anyone who isn't a gardener. Still, if you hang with it, he moves on to the more practical matters such as how light affects your health, and your children's health.
Case in point is the video of an African American child who is in a class lit by one type of lighting. He is sitting at the back of the class, agitated and disinterested, and seemingly with ADD.Read more ›
