Do You Know How Cameras Work?

The photograph of an American sailor kissing a woman in Times Square in celebration of the end of WWII has become an iconic image. And Marilyn Monroe posing over a New York City subway grate. Did Americans' love of photography start when the original Kodak debuted in 1888. Or was it with the camera-for-the-people, the Brownie? Or is it that the best photos are taken now that the most prolific digital camera is the one built into our iPhones?

The first camera to capture and store digital images wouldn't be developed until 1975 -- and you'll never guess the available megapixels it had. Ready for it? The first digital camera had only 0.01 megapixels to capture images, which were black and white, and saved onto cassette tape (which would later be replaced by a more user-friendly flash memory). And just a little more than a decade later, Nikon introduced the Nikon SVC, which was the world's first digital single-lens-reflex (DSLR) camera. Where do smartphones fit in? Well, in 2000, Sharp introduced the J-SH04J phone, the first cellphone designed with a built-in camera.

Yet, when it comes to the camera, things haven't really changed that much -- at all. At least not the basics. The fundamentals of how a camera functions remain the same now as they did in the 19th century and earlier. And no matter what subject matter you prefer, photography is simply the study of light and shadow, and the camera you use is your tool for capturing it. But there's a little more going on than the click of a button when you take a photo. See how much you know about how cameras work, from point-and-shoots to manual SLRs, and more. Say cheese!
