The question is mainly in regards to on-camera flash per se, whether hand-holding or with use of a flash bracket. Otherwise, with a one flash setup near the camera.
I relize one obvious objective is to get the flash higher BUT would it also be preferable to have it off-center also? Whereas the flash is a little off to one side versus direclty over the camera/lens. Is this called off-axis?
If this is the desired, as it seems I read somewhere, what about in case of group shots? Wouldn't this cause a side shadow -or- is a slight side shadow desired in also helping with depth?
