SHUTTER SPEED EFFECT NOTES
-Shutter speed is used to control exposure, but it is also used as a creative tool that freezes action or adds dramatic blur to moving subjects 

-switch to shutter priority, you set the shutter speed and the camera sets the aperture, actual shutter speed is adjusted by a dial, but make sure to always check your cameras manual

-The basic principle behind using fast shutter speeds is moving, the shorter the shutter speed, you need to freeze the movement 

- A shutter speed of 1/250 sec will freeze most slow-moving subjects, a speed o 1/1000 sec will freeze faster subjects such as a car 

-theres more to getting successful action shots than just selecting a fast shutter speed and firing the shutter
