Quick question.
If I expose for the ambient light in a shot, but am using off camera flash as well, then what keeps the flash from over exposing the subject?
For instance, it's twighlight and I need 1/25 sec and f/8+ for depth of field. If I pop a flash on the subject at those settings won't it blow out the subject?

Lower shutter speed = more ambient light in shot.
To answer your specific question, you would need to use a light meter or take some test shots and adjust the output of your flash till you get the right balance. |

Ok, easiest way to do this. Set your apeture to the flash. Once you have correct exposure for your flash you start playing with your shutter speed until you get the balance you are looking for. This is the easiest way because you only have to set the camera and not continually adjust the flash output. Remember that you have to stay within your camera's sync speed though.
HERE is a link to the Strobist blog spot. The link is to the specific part on balancing ambient light at twilight with flash. I highly recommend reading the entire strobist 102 section.
