I recently ran across this tutorial on 500px.com and I immediately found the type of photography I want to do! However, I currently work exclusively with continuous lights. I have found several tutorials on this technique and most of them can even be shot outside with a fair amount of sunlight (once you add a strobe). You basically set exposure to complete darkness with ambient light, and then bring in a strobe at low power. It's a trial and error process that eventually gets you there. But for me to pull off such a low key exposure, the model will have to be perfectly still, and I'll have to be on a tripod to keep things steady enough for the exposure to work (or wind up with a very shallow DOF due to the wide-open aperture). Is this sort of goal just not meant for continuous lighting? I've gotten close with shots like this: https://500px.com/photo/91380219 --but you can see from the blurry back of the scarf that the aperture is wide open (f1.8) so not everything can be in focus. Am I doing it wrong or is it simply not possible to pull this off without strobes?
