I'd like to be able to take slightly long exposures, with a flash at the end, and someone in another forum told me this was called something like a "second curtain flash". My question is, does a rebel xt support this, and if so how?

Thanks in advance!

Custom Function 9-1 is what you're looking for. There you can change the flash syncfrom first curtain (when the shutter opens;9-0)to second curtain (right before the shutter closes;9-1). You access Custom Functions in Set-up menu 2. There ya go. Have fun!

ok, another silly question...

i set it for long exposures (like 2 seconds) and set the flash to 2nd curtain... but what happens is i get one flash on 1st, and one flash on the second.... how the hell do i turn of the first one?

Thanks again!

well, I have no samples, but in my case, it would work to capture a blur of movement, and then a more "solid" picture at the end.



so if a car was driving by, i'd get a blur of the car, and then at the end, a solid shot of the car.

LIKE A NIGHT PIC OF A CAR GOING BY... YOUD GET THE LIGHT TRAILS AND THEN THE FLASH WOULD LIGHT UP THE CAR SO YOU COULD SEE IT IN THE PIC.

The 1st is just a preflash for the camera to measure the exposure - only the 2nd one counts and is the real one. You can not turn off the built-in preflash

With an external unit you can put the flash on manual and there'll be no preflash then...
(i.e. there'll still be a preflash if you use the external unit in automatic mode)
