    Just a thought - (until fairly recently) lenses have always been circular so how come we ended up with squared images?

    answers on a round postcard please ..

    Funny, I was thinking about round photographs a few nights ago, while watching La Roue (French silent film) on PBS. Portions of that movie are filmed in a round format.

    I'd always figured images were squared due to film handling and conservation, but I wonder if there is also a more technical reason? Vignetting?

    No vignetting as I understand it comes from the square in a circle (or outside it)

    OK, well then I'm sticking with "material conservation".

    It is the same reason that we have square cars with circular tires:)

    If you close one eye you see in the round format. If you open both eyes you see in a rectangular format.
