I recently found this great video from Asap Science on the relative nature of our perception of reality.  It has excellent examples of how we judge what we see in context and not by absolutes.

In other words, our perception is influenced by our surroundings.  This adaptability of our senses – it’s true of our hearing as well as our vision —  is part of what we think about every day at Dolby Laboratories to create amazing experiences for people. It is anomalies and surprises like these that make each day fascinating and exciting.
