    ... why are lenses round

    and images almost always oblong or square?

    That can't be right ...

    Then try making a round film holder ...

    Rectangle does seem to be favourite for pictures of any sort ?

    Wonder if that's why the mirror in the camera is rectangle?

    What about round ham slices on rectangular bread?

    The original Kodak camera did produce round pix, which makes the best use of the lens's image circle. Some fisheye pix are round.

    Lenses are probably made round because round shapes are the easiest to produce with normal machine tools. Ever tried to drill a square hole?

    The image that comes out the back of the lens is also round, it's the film or sensor used to record it that's rectangular.

    And producing a rectangular or square printed image results in far less waste.

    Why is a round of bread square?

    The best lens hoods are rectangular but hardly anyone makes them.

    Buy a "full frame" digital camera and use a crop (APS-C optimised) lens on it and you almost get the best of both worlds...

    I guess its what is easiest to manufacture - my guess too is that what you are looking at right now is in a square or oblong format - but actually what your eyes can see is a much larger orbital or circle around that screen or monitor.

    With digital photography we do have the ability to only ever present images in a circular format (or a whole load of other shapes and formats) if we so wished - but nobody ever does.

    Would round or oval cinima screens be much more relaxing and give a more natural and realistic feel - my guess is that they would - but that it might be just too expensive to do? So maybe we should have a go at some radically different formats and see how they fare here on EPZ? Does anyone fancy a bit of a challenge?

    Anyway - thanks for your comments on what was an irreverent bit of foolishness on my part.

    Cheers

    Robert
