So I'm visiting a good friend of mine and her dad is currently working on a music video for band, knows I do lighting stuff and wants to put me to work, im not entirely sure to what capacity, but I would rather too much for what I need to do that to little, so here is my question, how do you use color correction, Do you gel it in with every light or just the ones that would be no color? What are the different types and how are they different? If I end up doing a design for a music video thats like a vid of a performance any tips for lighting in that situation.
