Wait, what ever happened to balancing through a 1/2 CTB gel on to white paper to get a warm effect. What's Rosco gel sampler cost...$2 or $3, probably free at a lot of places. That's always worked for me. Of course this says nothing to the decision of on-set warming vs. post, but come on, $60 for blue paper...ouch.
