How do cameras know what the world looks like?
February 14th, 2010 | by admin |I don’t understand how cameras can capture what the world looks like when it looks different to all kinds of different animals. For example, some animals see in black and white, others are color blind, so how is it that cameras capture exactly what we see and not like other animals? Or is it just that we can only see some of the colors the camera really captures?
Cameras that you buy to take pictures are made specifically to capture the light that the human eye can see (in pretty much the same way that your eye does). There are many other types of cameras – night vision, IR, UV, electron, etc. all see different kinds of radiation.

When you look at something you aren’t actually seeing what you’re looking at. Say you’re looking at the Mona Lisa. What you are seeing is actually the light reflecting off of the object and not the object itself. It’s kind of hard to absorb really.
Now, cameras do the same thing. Cameras take the light reflecting off of an object and put it on film, or a digital sensor. The things you speak of (color blindness, seeing black and white) are deficiencies/handicaps within whatever being you happen to be talking about.

Cameras and film are designed by man so they will design them to capture an image as closely as possible to what a "normal" persons eye will see.
