This video offers another series of ways to look at the effects on image exposure from changing Shutter Speed, or Aperture, as well as the benefits of changing ISO to help achieve a proper image exposure. Its a long video (15min) in part from a review of the standard exposure “stops” for Shutter and Aperture, and a lot of redundancy to try to drive the terminology home.
