    I am currently doing a photography course at college and had an
    assignment for flash synchronisation. simple I hear you say, but oh no
    it isn't. I need some help.
    The set up is a Canon EOS500 with a Jessops 280AFC flash gun attached.
    Take a photograph with flash at the following shutter speeds, 1second,
    1/8th, flashgun setting, 1/250th and 1/1000th.
    When taking the first 3 these are okay. BUT trying to take a shot at
    250th and 1000th, my camera just is NOT having it. When I set to
    manual and set 250th, on pressing the shutter button it resets itself
    to 1/90th (my flashgun setting)
    I have tried to change this by using the TV setting to overide and it
    just won't work.

    Can anyone please explain this, I need photographs for my coursework
    and it just isn't working. Is something wrong with my camera? Or am I
    doing something wrong.......please help asap

    I bet the camera won't let you do it.

    Find your instruction manual where it says a dedicated flash will always
    automatically reset a faster shutter speed to 1/90. Explain it to the
    instructor. He will probably forgive you. Don't worry about it.

    If even one other classmate has a mechanical camera that can do this
    assignment, you can learn by viewing his example. The point is knowing what
    to expect if you set a speed that's too fast.

    As you may have read, the shutter is fully open, that is the front curtain is
    fully open and the rear curtain has not yet started to close at a certain speed
    called the flash synch speed.

    Older cameras would shoot anyway regardles of the speed, and fire the flash when
    the front curtain opened, even if the rear curtain was covering part (up to
    most) of the frame.

    The instructor wanted to demonstrate that effect by you creating images with the
    rear curtain of the shutter covering part of the image when the flash fired.

    Recent cameras (many over the last 20 years) are often too smart for photocourse
    instructors, and will not allow the flash shot to proceed if the shutter speed
    is too high and/or will reset the speed of the shutter to max synch.

    Try the camera in Manual mode at your chosen aperture and the faster speeds.

    (If the camera has a seperate synch connection then a flash connected to that
    connection should always fire.)

    If that still doesn't work, bring the camera (and manual) to class and show the
    instructor that the camera will not fire / will set synch speed.

    Cheers,
    Alan

    The camera cannot synch with flash at any faster shutter speed than 1/90th.
    Either your prof is having you on, or he is assuming you have a leaf shutter
    camera.

    Have you tried pure manual mode?
