Had my camera along to document an evening event. Usual set up: Canon 6d, 24-70, Speedlite - no off-camera gear, etc.. I am quite comfortable using bounce flash.
However, this event was in the green room. Green all over the place: walls, ceiling - even the floor had a green tint. The result predictably: all pictures have a very strong green tint that can not completely be compensated in post. Especially getting pleasant skin tones is very hard.
How do you deal with such situations? Any suggestion how to get better colors (except painting walls and moving the event...).
