Newbie here! Is it okay to have a combination of Tungsten key light (softbox) and daylight as a fill on interview shoots? I did a test earlier and tried using an LED light as fill but the color did not match (it has a greenish tint.) I shot the video and there was daylight coming through a window but it was diffused somehow so it was not as strong. I have a lamp that was on during the interview that served as my background light. So.. back to my question... is it okay to do this? Is there a rule for this?
