Light Sensitivity of the Human Eye.

As the low-light capabilities of high-end (and even low-end) cameras rapidly improve, it’s easy to marvel at technology and forget how amazing our own eyes are, but here are some mind-boggling facts to consider: did you know that the human eye can detect as few as two photons entering the retina, and that, under ideal conditions, a healthy young adult can see a candle flame from 30 miles away? To see how mind-boggling that is, try using Google Maps to find a location 30-miles away from where you live.

According to neuroscientist Bradley Voytek, the reason we don’t utilize our full sensory potential is because we’re not paying enough attention to them — kinda makes you want to put down your camera and focus on staring at things, huh?
