In tricky mixed lighting situations, I frequently use my Expodisc and take a preset WB (which generally works great). However, occasionally the photos are a bit on the cool side. What’s the best way to get a bit of warmth back into the shot. I’ve tried messing with the hue settings, but I feel like I’m adding a color cast rather than warming it up. Any ideas? I’d hate to have to invest in the warming version of the Expodisc.
