Looking for technicial advice.

I have a CP990 that is collecting dust and I would like to adapt it for intra-oral (dental) photographs. The only modification desired is to get the flash to a different location. From a technicial view, would it be possible to attach an additional small flash (strobe and reflector only) on the opposite side of the lense from the factory flash? Ideally I would try to get the idenetical parts from Nikon and then wire ir in to the f actory in series. I believe this would still preserve the camera's ability to adjust the flash output as required. Can anyone recommend a source for the parts or will I need to canabilize a small point and shoot?

I realize any support from Nikon is not likely and warranty work is out of the question in the future. This is a great camera, that will give all the resolution needed for my purposes (Powerpoint).

I even considered utilizing fiberoptics to move some of the light to the other side but have not fully explored yet. I will probably try this first because it is fully reversible. Anyone have any ideas about this approach. At a quick look, the light seems to transmit ok but the dispersion at the output end will need some control. Just another approach I am considering.

My goal is to get at least two light sources on opposite sides of the camera to reduce shadows and preserve the CP990's ability to adjust flash intensity. Actually, a ring llight would be best but can find one for the camera.

Thanks in advance for your comments.

Any comments or other suggested approaches appreciated.
 
would to just get a circular light tube and set the white balance accordingly and shoot through the middle. You could even add a reflector and still shoot through the center.
