Angles of Reflection is a series of articles written by Da-Lite which reviews the best practices for designing and specifying visual displays coupled with application basics for today's challenging system designs.

In December 2009, Adam Teevan wrote an article that exposes common myths surrounding ambient light and projection. In this article, Adam discusses the following myths:

Moving the projector closer to the screen will brighten the projected image.
Light sources between the projector and screen will directly interfere with the projected light.
A completely light-controlled environment is a completely darkened environment.

Here's a summary of this issue of Angles of Reflection:

--------------------------------------------------------------------------------

Our traditional myths have survived for millennia and continue to resonate as insights into the very nature of humanity. Other myths, unfortunately, are related to AV. While they have the potential to be just as enduring, their contributions to the human race are often negligible and rarely positive. This article will investigate just three of these, all related to light in an AV system.
