How a Camera works
How a camera works
Today we have digital cameras and only a few years ago, most of us had film cameras, but it’s unlikely that you’ve given much thought to how they actually work.
The most basic explanation of how a camera works is fairly simple. First, a camera has a component called a lens which is simply a piece of glass or plastic that is curved. When the camera is pointed at an object, light beams bounce off the glass and flow through it, recreating the image in front of you. The glass is curved to allow the light to hit at an angle, making all the different light beams hit the film.
The film is a chemical that is able to record different levels of light received through the lens. Once the imaged has been recorded on a film, it then needs to be combined with other chemicals in the developing process to produce a picture.
This of course is a very simplified explanation of how a camera works and for the average person is as much as you will need to know. Those with scientific backgrounds will of course be able to give a much more detailed account of how a camera is able to take a picture.
