Lecture description

How does a camera work? This is the first step to understanding how to take better photos.

At its core, photography is about capturing light. Your camera can see bright light, and if there’s an absence of light. It can see colors too!

That light goes into your camera through the lens, which has an aperture inside, an opening that lets in the light. The light passes through the camera’s shutter which in many cameras opens when you press the ‘shutter release’ button to let light in… and the light hits your camera’s sensor, where it is digitally captured and saved as an image.

While digital photography is a lot easier than photographing with film, the process is still the same. And as one of the most important inventions of all time, we’re excited to have you in this class to learn even more.
