Tone studies are killing me. Should have probably picked an easier environment to render other than the bridge of a spaceship. Part of the reason I'm doing these is to get the mind geared towards thinking about the lighting and environment when coming up with a composition; that and to try to vary from shot to shot the amount of space and distance being used. In short, to get away from close- and medium- and to feel comfortable with long-angle shots to convey the mood and acting. The challenge of having a somewhat detailed environment (which includes lighting) is to not shortchange it and to see it through to the end. Tends to make the work bottom heavy, since rendering the background's probably the last thing I get to before the tone work.
