I want to film dance instructors teaching about 10 - 20 feet from my camera.
Since I am an amateur I have no idea how to light this. I would try to make sure the room has plenty of light from "standard" sources (ie, ones tha that come with the building). But I imagine I need some lights in front of the dancers too, ideally on the cheap side and portable.
From my research it seems that perhaps LED light panels may be a good option? I don't know how many to use, or if they should be in the front or at diagonals.
I don't know if I need some kind of hair light, or how to acheive that if I do. I don't know if I should light the background behind the dancers.
Thanks for any suggestions, and if this is a common problem / technique perhaps you can tell me what the "name" of it is and point me to any reading/viewing material?
Below are some common rooms and setups where dance might be taught (these are not me by the way. I'm just trying to understand how lighting might be set up in these contexts.
