Your exposure, or the amount of light that reaches your cameras sensor, is determined by a few combined variables: ISO, aperture and shutter speed.
ISO is your camera's film or digital speed. ISO should be set first and manually from 100 to 6400 speeds. The higher the ISO, the more sensitive your camera will be to light and the easier it will be to capture your subject if it's in motion or in low lighting conditions.
The aperture is the diameter of the opening allowing light to your cameras sensor. Aperture is read and represented by a number ranging from 1.4 to 8 called an F-stop. The lower the F-stop number is, the wider the opening, the brighter the image.
Aperture or F-stop also determines what area of your subject is in focus or your depth of field. Larger F-stops (F/22) produce a longer depth of field, allowing objects at a wide range of distances to all be in focus at the same time while an F-stop of 5.6 would focus only on the foreground.
Shutter speed is the time that your shutter remains open and is represented in fractions of seconds. To freeze action, choose a faster shutter speed like 1/1000 and for motion blur, choose a slower speed!
