This simulator is meant to demonstrate the affects of shutter, aperture, and ISO on the exposure of a photograph. The principals apply to both film and digital cameras. There are three primary affects that can be observed.

• Aperture - The higher the number, the smaller the opening size, and the greater the depth of field.
• Shutter - The slower the shutter, the more moving objects such as the people, will blur.
• ISO - The higher the ISO, the more sensitive the film or sensor is. Side effect is the higher the number, the greater the noise.
