How Does a Camera Work?

ready to go and snap your winning photographer of the year photograph. But do you know how does a camera work?

If you’re an avid photographer, or someone just starting, maybe it’s time you find out. In this short guide, we’ll take a look at how a camera works and why you should know. Let’s jump straight in.

How Does a Camera Work? As technology pushes forward at an alarming rate, we find ourselves using complex gadgets regularly without knowing exactly how they do what they do. Take, for example, the camera.

Perhaps you’re getting

A camera consists of two main parts, the lens, and the light detector. The lens of the camera captures the light and then projects it onto the light detector surface inside the camera. This is either a film or a digital sensor depending on the type of camera you’re using.

How Does a Camera Work?

The Lens

In its most simple form, a lens is just a curved piece of plastic or glass. It redirects the beams of light that bounce off an object so that they come together and form an image.

How it does this is quite simple. Light travels through the air and the glass at different speeds. The lens slows the light down.

Now, a camera lens isn’t just one lens. It’s made of several single lenses and different lens groups. These different configurations are what allow us to have so many different types of lenses such as:

  • Telephoto lens
  • Wide-angle lens
  • Fisheye lens
  • Macro photography lens

All of these different lenses use different configurations to give different focal lengths, apertures and focus.

The Light Detector

In analog cameras, the light that is collected from the lens is focused on the film that is stored inside the camera. This film is covered in chemicals that react to the light and record the image.

In digital cameras, the image is captured on an electronic chip instead of a film. The chip inside a digital camera is a light sensor that converts the image into electronic signals. This allows the image to be stored digitally.

Modern-Day Photography Tricks

These days, when you see a striking image, it’s often manipulated in some way. Digital photography has allowed images to be processed in several ways. Time-lapse photography is a great example of this. There is a definite art of how to shoot time lapse, but it is all made possible by technological innovation.

A lot of what makes a photograph so striking is the processing the image goes through once it has been captured.

Before You Buy a Camera

Before you get out the camera buying guide it’s advantageous to understand how a camera work. By understanding the simple principles behind the function of a camera you can make a better decision about the type of camera that is best for you.

Remember, before you buy a camera, you should what each type of camera and lens is designed for so you can capture the best image possible.
