We played around more with shutter speed in my next assignment for ART142 at Chandler-Gilbert Community College. This assignment was called time shots. Basically we experimented with both freezing the object in motion by a faster shutter speed or blurring the object by slowing down the shutter. The shutter speed is the valve that controls how long the light flows through the lens and onto the image sensor. The smaller the aperture, the longer it will take a given amount of light to flow through the funnel and the longer the required exposure will be. This was a fun assignment and it usually requires a trip-pod. I took some of these photos of the Valley Metro light rail around ASU campus.
