The exposure triangle shows all three aspects of exposure and the balance between them.
Shutter speed or exposure time is the length of time when the film or digital sensor inside the camera is exposed to light. A fast shutter speed freezes movement, while a slow shutter speed blurs movement.
Aperture is the opening in the lens. The smaller the hole, the less light the camera lets in and vice versa. Aperture is measured in f-stops. When your aperture is larger, your depth of field is shallow and when your aperture is smaller, your depth of field is wide.
ISO is the cameras sensitivity to light. The higher the ISO, the more sensitive the camera is to light and vice versa. When it is sunny out you use automatic, or around 200. When it is dark out you can start at about 400 and continue to play with it until it meets your criteria. When shooting in a gym with moving athletes, use at least 1600 or above.
White balance is used to make colors in photographs more accurate. There are multiple white balance settings like shade, fluorescent, and auto. Depending on your camera, there are different ways to set and adjust white balance.
