How to use an SB-900 for manual flash fill-in
I want to use my SB-900 with my D3 to fill in some shadows. With the D3 in P mode I put the SB-900 manual mode at 1/8 power. I find that the exposure changes between a shot with the flash on vs flash off. I had hoped that the camera would keep that same exposure and the flash would just add a little fill light. Is shotting the camera in the manual mode the only way to accomplish this?
