How Does a Camera Shutter Work?

Video Transcript

"Hello my name is Paul Morris. I'm a professional photographer here in Miami, Florida. In this clip we're going to talk about how a camera shutter works in either a digital SLR camera or a range finder camera. They, we're talking about a focal plane shutter. There are 2 kinds; focal plane or leaf shutter. OK. A leaf shutter is in the lens. Focal plane is in the camera body up against the film or digital capture. The way it works is when you trip the shutter, as you can see, it opens the shutter, opens the hole in the back of the camera that lets the light through. And that in corresponding with the lens which focuses the light on the film or digital capture, you get the image. And the speed of the shutter is controlled by the functions on the top of the camera or in the digital readout of the digital camera. Or sometimes it's just automatically adjusted by the camera, however you decide to set your camera. Now, the corresponding aperture and the speed of the shutter creates the correct exposure, based on how much light is available and how wide the lens is open, the aperture is open. For example. F2.8 at a 1/60th of a second would be kind of a dark area inside, whereas F5.6 at 1/1000th of a second would be an outside exposure, which would give you a correct exposure on the film or the digital capture sensor. Once again, this has been Paul Morris in Miami, Florida. Thank you for watching."
