Exposure Triangle

For your research this week you will make your own exposure triangle. You will hand draw (digitally or on paper) an exposure triangle that includes the following information:

• All the full f-stops for Aperture

• All of the full stops for Shutter Speed

• All of the full stops for ISO

• How the ammount of light changes (quantity (f-stop), duration (shutter), & sensitivity (ISO)) with each of the settings (for example if the ISO is 3200 is it letting more or less light in?)

• What happens to the photo when the settings change besides getting lighter or darker? (motion blur, out of focus, grainy)

We will begin photographing assignments in this class using manual mode. We cannot rely on the built-in light meter in your camera. In order to truly master photography, you must begin by shooting in Manual Mode and work to understand the ramifications of aperture and shutter speed selection.

There are three variables that control how much light the film will receive:

Aperture (f/stop) + Shutter Speed + ISO

Let's think of it this way each of these settings affects something different as seen above. However, they also all control the light allowed to reach the image sensor. Therefor they all must be in balance with one another to create the perfectly exposed photo.

Aperture: Controls Light & Depth of Field/Focus

Shutter Speed: Controls Light & Motion Blur

ISO: Controls Light & Digital Noise
