The next camera function I have been studying is shutter speed. Shutter speeds are a function of time and are indicated in seconds or fractions of a second. Shutter speed is the primary control for motion. A faster shutter speed is selected when attempting to freeze or stop a moving object. Shutter speed can also be used to show an object’s motion by causing it to be blurry. You should select your shutter speed based on how fast your subject is moving and how clear you want your picture to be.
Shutter priority mode allows the photographer to select the shutter speed desired for a particular shot and the camera selects the appropriate aperture based on the cameras ISO setting and the brightness value of the scene. This selection will always have medium in tonality and will not compensate for overly bright or overly dark scenes.
High shutter speed=less time/exposure=freezes motion
Slow shutter speed=more time/exposure=blurs motion
Ever wonder how they make running water look so soft and smooth? Shutter speed!
