Next up in the Exposure tutorial series is Shutter Speed, which is one of the more creative variables of exposure.  I say this because it can be use not only to control the exposure of a photograph but it can help to tell a story by controlling how you capture motion/movement (more on that in later tutorials).

What is Shutter Speed? - Shutter speed is the amount of time that your camera shutter is open for (TV Time Value).  The longer the amount of time your shutter is open for the brighter the exposure will become and the shorter the amount of time the darker.
