I shot a paid gig couple of days ago. I am not that experienced with shooting indoor environments. I shot tons of cycling races outdoor with crappy morning light. From my experience, if I don't overpower the ambient light, I would get uneven color (white balance in the scene). The location is inside a bike shop, not big. The shop is using some sort of halogen spot lighting with a yellow color cast. I was using a single strobe bouncing light off the ceiling. Using a beige color index card to get some light to the front. I have some shot high lights here:
Like this scene here, is that a way to balance the exposure level as well as the white balance using a single strobe? It is obvious the subjects closer to my light source would appear more brighter than subjects at the back. I had to play the level and contrast and a warmer white balance to create a gradual transition. I called it "preserving the ambient light." Of course, the ISO is pretty high here, 1600, to let in more ambient light. Otherwise, I would get a pitch black or semi-pitch black DOF or background.
