Exposure Triangle
A photograph's exposure determines how light or dark an image will appear when it's been captured by your camera. Believe it or not, this is determined by just three camera settings: aperture, ISO and shutter speed (the "exposure triangle").
aperture

aperture : a space through which light passes in an optical or photographic instrument, especially the variable opening by which light enters a camera.
shutter speed: the time for which a shutter is open at a given setting
ISO: how bright the camera makes the photo

shutter speed
when: use faster shutter speed such as 1/6400 if your trying to photograph a running player but if you use a fast shutter speed less light will get in .
ISO
When: the lower the iso the less light thats produced so use lower iso when its bright out side
