RECORDING MOTION
Freeze frame - a single frame forming a motionless image from a film or videotape
Motion blur - the apparent streaking of rapidly moving objects in a still image
F-STOPS
SHUTTER SPEED - the nominal time for which a shutter is open at a given setting
APERTURE - a space through which light passes in a photographic instrument
ISO - measures the sensitivity of the image sensor (international standards organisation)
2.8,4.0, 5.6, 8,11,16,22, 32 are common F stops
The longer the shutter speed is the more blurry your image is going to be therefore this is ideal for taking images of motion.
the numbers you have paced are f stops...
