  1. I haven’t read the thread there (because the interface is ugly), so I may be redundant, but I’m pretty sure it’s because digital cameras sample in a particular direction, rather than holistically. So assuming it goes top left to bottom right (like reading a book), at each row of sampling, if the thing was spinning fast, it would have moved some distance before the last sample, and you’d get a distorted look like that. If you look carefully at the picture you can see how at each row the blade would have been in that place if it was spinning.

  2. I’d say it’s maybe lack of technology.
    The guy said it was a 1.9 megapixel camera….that’s like a beta machine vs a dvd player now. Cameras up to 8 megapixels now.
    I didn’t even think they made cameras below 2 megapixels these days.
    That’s my uneducated view.

  3. I had the answer right away: slow row-readout. Image quality is a strong function of how the focal plane readout is done. You wouldn’t believe how many different ways there are to do this, and how to do it wrong.
    I believe most FPA “shutters” are electronic in nature, which just means there’s an integration time of the FPA elements that varies with light level. Ideally, the FPA would have all the elements integrate starting at the same time, and readout all elements simultaneously. Needless to say, the one in question doesn’t.
