Camera shutter-speed simulation
This Flash-based animation will allow the user to view a scene of a waterfall as if viewed through a single lens reflex (SLR) camera viewfinder, adjust the exposure settings by moving a (virtual) control dial which will alter the shutter-speed and reciprocal aperture setting, click the (virtual) shutter button, and view the resulting image based on the chosen shutter speed. Users will appreciate the difference in how the moving water of the waterfall is captured at faster and slower shutter-speeds. For example, at faster shutter-speeds, the individual water droplets are frozen mid-air, whereas at slower shutter-speeds, the water takes on a smooth, silky appearance owing to the blurring of the detail.
This resource will also help users appreciate the reciprocal values of shutter-speed and aperture in order to maintain the correct exposure when either one is altered.
