Understanding shutter speed
Brian Liepe: Videos comprised of series of stills, whether you're shooting stills or video, there is a digital shutter that allows light to enter each frame. Now back in the day, film cameras had a rotary shutter disk and there was a wedge cut out of it. Now the degree to which that wedge was open determined how long each frame was exposed. In these cameras, shutter angle was measured by degrees. Chad Perkins: DSLR's usually measure shutter speed in units of time, typically fractions of one second. Now if you slow down your shutter speed, you will increase exposure because you're letting more light into the camera that hits the sensor. But your motion blur will also be affected which we'll talk about a little bit later. Brian Liepe: As a standard, our frame rate determines our shutter speed, and now that we've learned that our shutter speed is measured in time, a fraction of one second, we can take the denominator in that fraction and make sure that it's double our frame rate. So if…
