Learning and understanding the basic aspects of a camera is not only interesting but also extremely  informal. Reading the first pages of this chapter- who knew there is so much to know about exposure? It all makes sense when explained, but it is never on the mind when looking at a photo or video a photographer took. 

I also enjoy learning about shutter speed. I think something like this is what makes a photographer unique. Learning that just the shutter speed can lighten or darken an image. 

Shutter speed is relatively simple to explain from a physical standpoint. There is a curtain in front of your camera sensor (called the shutter curtain). This curtain usually stays closed until you take a photo. When the camera fires, the curtain opens and fully exposes the camera sensor to the light that is coming through your lens. To end the exposure, the shutter closes immediately, stopping the light from hitting the sensor. (As a side note, the button that fires the camera is also called “shutter” or “shutter button,” because it triggers the shutter to open and close.)

On some newer cameras, you’ll find an electronic shutter rather than a physical, mechanical curtain. Or you’ll find both – many cameras have both a mechanical shutter and an electronic shutter. The principle is basically the same, but with an electronic shutter, the camera is electronically telling the pixels to start and stop recording the image.

In any case, using a particular shutter speed (say, 1/10 second) means that the shutter is literally open for that period of time (in this case, one tenth of a second).
