Hi Guys,

Say I am outside and use a long exposure to capture the background, how can I also have a person in the shot who will be crisp with no blur?

I have a 430exii, so I assume that this will help?

Thanks.
 
2nd Curtain so that the flash fires at the end of the exposure, should be a function on your camera.
 
It's easy. Put the camera on Av, and adjust the aperture and ISO so you get the shutter speed you want according to the ambient light. With the flash on E-TTL, press the release. The camera will then balance the flash output for correct exposure on the foreground subject. The very short duration of the flash freezes any movement. Done :thumbs: You can further adjust the balance of the exposure levels for both the background and flash indpendently with the compensation controls.

If the subject (and camera) don't move, there will be no blurring but if they do, you will get some blurred outline ghosting. Don't use second curtain sync until you've got the hang of things, it only helps if a) the subject is moving and b) the direction of that movement is important. Most of the time the direction of movement is not important and you probably can't control it anyway. In which case, second-curtain sync just causes other problems.
 
Craig, I've changed the image to a link as it did not appear to be one of yours. If I'm wrong, let me know.
 
Oh sorry Colin, I didn't know that, I will keep that in mind for future.

The image was actually taken by a friend of mine, whose website I actually host.

Thanks.
