Hello I am comming to one of the most important scenes of the movie I am shooting, the problem is that I have some dialoge of two actors at night inside a car, I tried shooting the scene with a portable flourecent light from walt mart that you can plug into the lighter for power, the problem is that i reviewed the footage and it flickers, what kind of light should I use to light up the faces of my talents inside the car at night? I dont have much money to spend, thanks a lot guys
