[* 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 whatin front of the lens sawupside-down and looked through the glass. As you can see, the upside-down graphic has been flipped right-side up!
[* black] ''Or so it seems…''

[* black] So why is it thatSo, if the lens flips the image? Wouldn't it be easierimage, why aren't all of the lenspictures from our digital cameras inverted?
[* black] Well,
just looked at the image right-side up like we do?
[* black] '''Science Time!''' In actuality,
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 not flipping the image upside-down, it is turning the image right-side up! Every timean integrated circuit. As far as our vision goes, we look at something,have the image is upside-down until our brain flips it over. The lens is undoing that.
[* black] But why??? You know that little hole
most advanced processor 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 thenworld to flip the image back over, until viola! The image looks right-side uparound: the human brain.
