Controlling Light

Your ability to control the amount of light passing through your camera lens will dictate whether your final image is sufficient, nice, or grandiose!  When a photograph elicits an emotional response from a person, we generally think it’s the subject, or contents and/or composition that draw out this response, however.  Lighting and the way the photographer controls it, is one big contributor to why a picture stands out as it does.  To get that amazing shot, a photographer may only need to make a subtle change to the amount of light passing through the lens, or a stark change in colour, direction or quality of light.  Ambient light in a scene and/or additional lighting tools and accessories, and a camera (aperture, shutter speed, ISO set accordingly) are all things used to obtain that perfect lighted image.

To start with the basics, we need to understand aperture, shutter speed, and ISO.  These three camera functions control the amount of light passing thought your lens.  Here is a visual of how you can alter the amount of light by changing your f-stop
