Our eyes as a camera

576 megapixels! That's right! The human eyes has detect over 10 million colors, and that's more than the world's most powerful Dark Energy Camera that shoots 570 megapixels images, capable of capturing galaxies 8 billion light years away.

While that may be high compared the 12 megapixels of an iPhone camera, things are a little more complicated. Human eyes view images differently than the images we capture in a camera lens.
We don't see every portion of the images with equal clarity. If you are staring at a computer screen right now, note that your eyes are viewing only one very specific portion of the screen(where you're reading from) and rest blurs out in a concentric manner, outwards. So, a single snapshot glance gives us an image of approximate 5-15 megapixels,(not a major improvement over the cameras). We get full 576 megapixels, when our eyes move around focusing through every portion of our field of vision.

Another important distinguishing factor, is how our brain holds this information. Unlike a camera that stores it as a 2 dimensional array of color pixels, the human brain detects objects through clues and cues, and later re-arranges them into a fairly obscure imagery. But that doesn't mean it's flawed.

Human beings have always viewed the world this way, even when picture perfect cameras weren't around. Technology might surpass us one day, and be able of capture images thousands of times more powerful , but it is important that we remember that the most beautiful paintings are those that are were once seen through the eyes of an artist, not the lenses of camera.
