Last night my dad asked me to come shoot his Lion's Club Parade of Checks, basically where they hand out all their donations to different organizations for the year. It was at this banquet hall with a funky red spot light shining on the stage. Almost all of the people have this red tone on them like the pic below. Is there anything I can do to get rid of it? I have lightroom but I'm not too familiar with doing a lot of PP. These don't have to be 100% perfect but I would like them a bit better. What can I do? Thanks.
