  • I think the “more to it” might be significantly crazier than the timing thing.

    Or ears have unique complex shapes that attenuate certain frequencies and bounce sound around in complex ways depending on the direction they ate coming from. And our brains instantly process all that stuff too. It’s why our sense of hearing isn’t just on a flat plane around our head.

    We have rocks that do math, transmit electricity, and fly us through the sky.

    When you get reductive about the natural sciences it all just boils down to applied physics which is applied mathematics.

    But engineering and technology? Applied geology.

    (/s because I’m not going to acknowledge that geology is applied chemistry and so on)








  • Our eyes and brains compensate for a lot of things that cameras do not. White balance is a good one, where things indoor under warm lighting can look orange while things out in the sunlight can look blue.

    I think perspective and distance correction with human faces is definitely one of those. So if you got the distance from the mirror correct, the effect might not jump out at you in person like it does with photos.


  • The numbers shown in that gif are the focal length, but the change in perspective is indeed actually due to the camera’s distance from the subject. When you are close to a person with a wide lens, their nose is considerably closer to the camera than their ears and hair, so it appears bigger. When you are further away with a nice telephoto lens for portraits, all their facial features are roughly the same distance away, so they all appear the same size.
