If the light doesn’t meet at the right point, the image will look blurry or out-of-focus. When all of those light rays meet back together on a digital camera sensor or a piece of film, they create a sharp image. A camera lens takes all the light rays bouncing around and uses glass to redirect them to a single point, creating a sharp image. While light bounces off of objects, it can also pass through objects - but, when it does, it can actually change direction. So how are we able to take sharp images in milliseconds today? A camera lens. Since that first camera did not capture very much light, it actually took eight hours to take a single photograph. When light hit the material, which through the course of photography’s history was made up of things from glass to paper, the chemicals reacted to light, etching an image in the surface. While devices like this existed long before true photography, it wasn’t until someone decided to place material that was sensitive to light at the back of that room that photography was born. Light would pass through that hole, and since it’s reflected in straight lines, the image would be projected on the opposite wall, upside down. The first camera was essentially a room with a small hole on one side wall. That means light rays are essentially bouncing everywhere in all kinds of different directions. When light bounces off an object, it continues to travel in a straight line, but it bounces back at the same angle that it comes in at. But, light also bounces off of objects, which is what allows us to see and photograph objects. When that beam of light hits an object, the light bounces off that item and into your eyes, allowing you to see whatever is inside the room.Īll light behaves just like that flashlight - it travels in a straight line. The light from the flashlight moves in a straight line. Now imagine you pull out a flashlight and turn it on. What do you see? Well, nothing because there’s no light.
