The Components of a Digital Camera
Now let’s spend some time going over the camera parts. First and most importantly is the lens. One of the keys to understanding photography is to think of the lens as an extension of your eyes. For the mechanics are indeed based on how our eyes work. What regulates the amount of light entering our eyes it’s what’s known as the iris? This corresponds to what is called the aperture in the lens. When we go out to the sunlight or enter a brightly lit room the iris shrinks. It shrinks down to lessen the amount of light entering our eyes and not flood our senses. When we go into let’s say a dimly-lit restaurant or a theater they open up wide to allow more light in so we can pick out the details. The camera lens works in the same way. The electronic sensors behind the lens registered the amount of light available for the picture. And the shutter between the lens and the receptors opens for a fraction of a second according to how wide the aperture is open.
On the more professional cameras, one has the option for varying this function known as exposure. This allows you an example of putting the background out of focus when shooting portraits or having everything sharp and then focused when shooting landscapes. For more in-depth understanding of this, explanations will be offered in our DVD for the more advanced photographer. But for the beginners rest easy for their simple controls and even the most inexpensive point and shoot cameras which will allow you some creativity when photographing. We’ll go into this in the next chapter.
