(This one's for the real experts)
Here is my concept: I want to photograph a nude model standing in front of an abandoned industrial building at night. I've experimented a bit with night photography, mostly because my Nikon F3 is capable of extremely long exposures in aperture priority mode, and the results were satisfactory. In all of my experiments the scenes were very static, now with a model... well, no one can stand perfectly still for 15 minutes. I was considering using a flash to light the model and then let the background burn in for however long it takes. I'll have the model stand still for as long as it takes, but I'm assuming if I give it an initial flash that the little bit of blurring from her motion will not affect sharpness too much, plus the effect may be cool.
My question really has to do with exposure calculation. My thought is that if a scene meters for say f5.6 at 15 minutes, if I set the flash to expose correctly at f5.6 and let the rest of the scene burn in for 15 minutes, then I should be all set. Obviously, reciprocity comes into play (I'll be using either APX100 or Tri-X at 400), so any opinions on that would be helpful. I'm going to do some tests with her in the next few weeks, but I wanted to get everyone's opinion on my technique first. Also, does anyone have any other method of calculating exposures for night photography? I really don't want to rely on the F3's AP mode all the time, I'd rather figure out another more concrete method of determining exposure at night.
Thanks in advance,
Ara
