1. The lower the f stop, the larger the opening is which allows more light to enter the camera.
2. The higher the f stop, the smaller the opening is which allows less light to enter the camera.
3. The shorter the exposure the less time the light is able to be seen in the image (basically a snapshot of an image)
4. The longer the exposure the more time light is able to be seen in the image (works well for this lab in particular)
5. What worked well for us was a low f stop and a longer exposure so we could capture the light from our phones and glowsticks.
