    What are the recommend camera settings for achieving light streaks from cars in the evening

    Is it a trial and error approach ?

    Canon 5D
    17-40 f4
    24-70 f2.8
    70-200 f2.8

    tripod as well.

    i think it'll be wide open aperture with long shutter ?

    yep stick it on exposure priority and experiment. It depends on the speed of the moving car really so you have to work out the shutter speed for streak length you need. Also have a look at second curtain sync flash. (Its in custom functions) This fires the flash as the end of the exposure so that the car will be sharp and unblurred with the bright lights shooting out from behind!

    The actual speed of the cars is important. Just taking off from traffic lights; travelling at 30kmph; travelling at 80kmph all require different shutter speeds.

    In actual fact I would recommend you try Av mode (aperture priority) and try a number of shots from wide open to fully closed down on the aperture.

    The numbers can get a bit confusing here as the camera will show you 1/3 stops as well. Depending on the maximum aperture of the lens try using the actual full stops as follows: f2.8, f4, f5.6, f8, f11, f16, f22, f32, f45, f64,

    the built in flash should be adequate.

    There is no built in flash on a 5D ... but would a typical built in flash have the range in any case ?

    I would have thought this is a job for a speedlight ... thanks for the tip though ... I've never tried this type of shot with a second curtain flash. I'll give it a go some time to see what happens

    The horror!:eek:

    It depends on the subject really regarding the power of the flash.

    Firing flashes at moving traffic on a public road probably isn't such a good idea anyway. Either you might cause a crash or be mistaken for some kind of shady speed camera operator :)

    Someone posted up some shots for C&C a few months ago or cars at night. They were really good, /goes digging...
