In this next part of the tutorial series and moving on from ISO and Shutter Speed we are going to be looking at aperture and the affect it has on exposure.  Some of you may already be aware that aperture not only controls your available light exposure but also your flash exposure (This is true of ISO also) but we are not getting in to flash yet, more on that much later on this blog.

The reason I want you to concentrate on just available light exposure and the fundamental exposure triangle (ISO, Shutter Speed, Aperture) is because I want you to get this nailed down before you go learning flash or buying that new camera or lens.  Walk before you Run.
