Cameras are really cool.

Let’s talk Cameras. They’re cool. If you didn’t know that, you should have read the title: "Cameras are cool."

Now that we have that out of the way, let me answer why. Why are cameras so gosh darn cool?

Let’s go back to the beginning. God created light, and

Ibn al-Haytham created a way to capture it. He was so cool. He was dismembered, decapitated, and then burned. But before that, he invented the camera obscura (not the band). A camera obscura is basically a tiny hole that lets light in. Behind the hole is a plane on which the image outside is projected. This is, however, not a perfect representation. The image that is projected is upside down and flipped.

Fast forward to the 1800s, and Louis Le Prince has just invented celluloid film. The film works by having light-sensitive crystals on a strip of plastic react to concentrated light through a lens. And if you take 24 of these pictures in a second, you get a movie.

Pretty Fwiggen Kool!

I forgot, you have to project the film to get a movie. So the projector is a light bulb with a lens. The light goes through the transparent parts of the film and is blocked by the opaque parts, giving you black and white.

Fun fact #1) Steven Speilberg first made muzzle flashes in his short films by cutting out film where he wanted the flash to be.

Now, digital cameras are a whole other beast. They use sensors and processors to capture light. In a typical one-chip camera, each pixel is made up of photo sites. There are twice as many green photo sites than there are blue or red. This is why the switch was made from blue to green screen.

Anyways, cameras are cool.
