What settings I used for this assignment are that I kept my shutter speed at around f8-9. I made sure my aperture was at a good enough level so that nothing looked too bright and difficult to see. Also, it took a bit of time to make sure that every single one of the photos looked right and it got a little difficult involving timing the shots. However, I managed to get the right shots at the exact time that I needed them.
f8 or f9 would be aperture settings, not shutter speed. Shutter speed is duration, so is measured in seconds, or fractions of seconds, such as 1/500 or 1/30.
