Shutter Speed
Defined most basically- Shutter speed is "the amount of time that the shutter is open"
-Shutter speed is measured in seconds, or fractions of seconds.
-Shutter speeds available to you on your camera usually double with each setting. 1/500, 1/250, 1/125, 1/60, 1/30, 1/15, 1/8 ect. It is good to keep this doubling in mind as the aperture settings also double the amount of light that is let in ( increasing shutter speed by one stop and decreasing aperture by one stop should give you the same exposure (with different depth of field and movement).
-To freeze movement in an image you will want to choose a faster shutter speed and to let the movement blur you would choose a slow shutter speed.
-If you have a shutter speed slower than 1/60 of a second then the camera needs to be on a tripod to avoid camera shake.
-Focal length is another thing to consider. If you are using a lens without a stabilizer then a good rule of thumb is use a shutter speed with a denominator larger then the focal length.
-All three elements in the exposure triangle work together to capture the correct exposure, if you change one, you need to change one or both of the others to compensate for it.
