I usually can get the settings right when it's off the camera. whenever i take them using it on my camera, the photos usually turn out very very underexposed in the background.
How do i bounce my flash for a nicer light filling the foreground and background. clue me in.
There will be situations where the flash cannot reach if the background is too far away. Depending on what you are shooting, how you shoot would make a difference.
For example, if I want to take a night scenery where I want to see the lights of the background, but I am in the foreground, what can I do? If I just use the default flash with the camera settings, I'll get underexposed background and little lights and scenery, and a possibility that my face gets really lit up. For such a thing, you will nead rear-sync flash where you let the camera have time to take the background exposure, and then right before the shutter closes, it will fire the flash just enough to light the subject in the foreground.
However, if you have a situation where you are in a big hall, and it is relatively dim, and you want to take a photo of a fren in the foreground and still capture the background scene, then you may have to have multiple flashes controlled by your flash commander so that the other flashes placed behind the subject would light up your background.
Bounce flash would work if the room is not too large, and the ceiling is not too high. You angle your flash upwards, and you can also use a flash diffuser to "spread" the light". If the room is too large, then the light bounce from the ceiling would not reach the back, or if the ceiling is too high, the light thrown from the flash may not be powerful enough.
Having said all this... that is where fast lenses come in. Try a f/1.4 lens in that situation without flash and you may get the results you desire
