Shutter Speed
Shutter speed is measured in seconds, going from fast shutter speeds of 1/1000 of a second, to slow shutter speeds of 30 seconds. A slow shutter speed requires a tripod otherwise the motion will be too blurry due to human error. When I took the photos of the balloons I needed a fast shutter speed so I used TV mode, and I needed enough light to get in considering the fact that the aperture would only be open for a fraction of a second I needed an
ISO of 200. When making the light drawing I used a slow shutter speed to capture the motion of the light.
