How to Turn Your Room into a Giant Camera Obscura

National Geographic created this nifty little video teaching how to turn any room with a view into a giant camera obscura. For an even more challenging project, you can try setting up some photo-sensitive paper (either photo paper or paper you paint with emulsion yourself) on the wall to shoot giant photos with your giant camera obscura.

    Isn’t this how Johannes Vermeer (the Dutch painter) painted some of his paintings? He projected the image on a canvas and used a pencil to ‘sketch’ the scene and later he ‘painted by numbers’ ;)
    I think they showed it on Discovery some time ago. The perspective seemed wrong and this technique explained it.

    A similar effect happens in my room. There’s a tiny slit area between the black curtain and the window and just outside my the window I have a concrete light colored floor. So whenever anyone walked by, their skewed image was projected onto my ceiling via the light between the curtain and the window.
