It seems every book about photo techniques I read stresses the problems inherent with built in on camera flash. I have a Nikon D40 and a Nikon D300, both with this feature, but every photo technique that describes the uses of flash recommends a mounted flash that whose angle can be tilted toward the ceiling to be bounced, or perhaps used with an extension so the flash does not reach the subject on a parallel plane. I have seen suggestions about using built in flash at reduced settings to diminish shadows on subjects taken in sunlight, but that's about it. Also, I've seen recommendations about the use of an on camera flash to trigger a strobe using a wire or wireless trigger (which I have used with my strobe set). The trouble with the latter function, it seems that no matter how reduced the setting is on the flash it creates frontal lighting which defeats the purpose of having a strobe set at an angle to the subject or behind the subject, etc. I've even tried putting a piece of translucent tape on the flash and have bought a plastic diffuser that mounts right on the camera to diffuse the flash, but they don't seem to make much of a difference. Bottom line, why hasn't a camera company developed a swivel style built in flash, so one wouldn't have to go out and buy ANOTHER accessory, i.e., a swivel flash that costs $150-$250? I've considered a way to create a DIY gizmo that would use a small mirror so that it could angle the built in flash so it could bounce off a ceiling or reflector. Has anyone created something like that or can it be purchased. As it stands now, to me, the on camera flash serves more as a "plug" for another accessory.
