    The described phenomenon has a practical reason; cartographers used to work with paper maps on desks. Since most people are right handed, desk lamps (and candles, in the older days) are usually positioned on the left side of a table, so that you‘d have the written words illuminated while your hand casts it’s shadow away from the writing. So in order for cartographers to not get confused, the shadows on maps are oriented so that they would line up with any other shadow on the desk!

    1:50 it takes me a little bit of mind effort to perceive "Concave" as actually concave, most of the time I perceive it as convex as well. I wonder if it's bc I'm more used to artificial light sources than sunlight, which would mean my brain will usually perceive the light as coming from whatever direction is opposite to the shadows.

My parents didn't understand that though so they thought I had some mental issue. 😅 Later when I understood this concept I tried really hard and did it in real life with a clear cube and basically it looks like the front and back faces are switched which is really weird. Its hard but I know a few people who can do it too.

      I have a very dependent eye, so my depth perception was pretty bad too. I remember my optometrist showing me a bee that was supposed to look 3D, but it only ever looked 2D to me. Old 3D movies wouldn’t look 3D. The real D 3D is better though- either that, or my right is less dependent on my left than when I was younger.

  • @jasonspence
    @jasonspence 7 років тому +6

    I found lots of them only half worked. For example, at 1:48, Convex should have had shadows extending past the bump, casting a longer shadow. Concave, on the other hand, had some oddities, like the inner sides of the lower left corners of 'o' and 'c', that gave it the impression of being convex, but having been spray-painted black or something (odd that I feel this rather than feeling like the light source was on the bottom right).
    I think the Grand Canyon picture worked so well because it has many layers and terrain colours, so it is hard to know where shadows would be, if it were a mountain range.
