| [* black] It's time for everyone's favorite segment: ***Science with iFixit!*** We decided to have a little bit of fun with the Hero3's lens and one of our [product|IF145-123|iFixit Guitar Picks]. | |
| - | [* black] For this simple demonstration, we placed a guitar pick behind the lens, upside-down, to see what the lens saw. As you can see, the upside-down graphic has been flipped right-side up! |
| - | [* black] ''Or so it seems…'' |
| - | [* black] So why is it that the lens flips the image? Wouldn't it be easier of the lens just looked at the image right-side up like we do? |
| - | [* black] ***Science Time!*** In actuality, the lens is not flipping the image upside-down, it is turning the image right-side up! Every time we look at something, the image is upside-down until our brain flips it over. The lens is undoing that. |
| - | [* black] But why??? You know that little hole in your eye that allows light through? The pupil—yes that's the one! When light passes through that central point, it is then projected onto your retina…but upside-down. Your brain must then flip the image back over, until viola! The image looks right-side up. |
| + | [* black] For this simple demonstration, we placed a guitar pick in front of the lens upside-down and looked through the glass. As you can see, the upside-down graphic has been flipped right-side up! |
| + | [* black] So, if the lens flips the image, why aren't all of the pictures from our digital cameras inverted? |
| + | [* black] Well, just like the lens of our eyeball, anything viewed through an optical lens appears upside-down until it's fed through a processor of some kind. For a digital camera, that processor is an integrated circuit. As far as our vision goes, we have the most advanced processor in the world to flip the image around: the human brain. |
