Shutter Speeds
The first side of the Exposure Triangle that we are going to explore is shutter speeds. Shutter speeds are measured in seconds or fractions of a second. The shutter speed determines the duration of time that the shutter is open for light to hit the sensor or film. The higher the number, the faster the speed and the lower the number, the slower the speed. A fast shutter speed, say 1/1000 of a second (which is often displayed in your camera as "1000" not as a fraction), will require more light be compensated. A slower shutter, say 1/4 of a second will be open for a much longer duration and would therefore need less light. Shutter speeds are one factor that controls exposure. One of the most important objectives in your learning the fundamentals of exposure is to memorize those shutter speeds! You will also need to know these for your quizzes and final exam (hint! hint!). Many sophisticated cameras now have not only whole shutters, but also have them in 1/3 increments. I know it is a lot of numbers, but not to worry. For now, all you need to memorize are the whole shutters that are present in the Shutter Speed Diagram.

Camera Simulator
Explore exposure with this camera simulator. Watch what happens the exposure and to the focus and motion when you use a slow shutter speed versus a fast shutter speed. Make sure you are in Shutter Priority so that you will only be adjusting the shutter speed.
