  1. Can anyone tell me the correct shutter speed for taking pictures from a
    television.

    Thanks.

    David.

    1/30 second.

    That's for US TV. The best speed would be different for different TV
    standards.

    It is probably any time greater than the screen refresh rate which is
    approximately 1/30 sec for US/NTSC television. Non-US is 1/25 sec.

    Hope this helps.

  7. Is that a question? ;-)

    You will probably be more satisfied with 1/15s.
    European TV sends AFAIK 50 half-pictures per second, each one containing
    (as the name suggests) half of the picture. This gives you 25 full
    frames per second.
    You should get a complete picture ieth 1/30s, but parts of it might have
    a (even) poorer resolution than the rest.

  8. That's correct for PAL as well.

    Frame refresh is 1/25 of a second so using a slower shutter will give a
    double image on a moving subject, while a faster shutter will often give a
    broken/split looking image which is the result of capturing the screen
    during the refresh.

    It's best to take a few shots because even a 1/30th you can still get the
    broken image affect.

    Part of it will also be exposed more. 1/25 would be the best, if the
    camera can do it, but mine can't.

  10. Which is PAL, frame rate 1/25 sec, so 1/30 is still the speed to use. You
    can still get frame effects on the photograph though. For static images you
    can use 1/15 or slower and this avoids the frame effect completely.
