<p>I am currently working on a short sci-fi film, and one scene involves a character going on a space walk. I've made a helmet, which has a plastic visor. The problem is that this visor is very reflective. All shots are in front of a green screen. My setup is fairly small, with a green screen stand and two soft-box lamps. The crew and equipment is fairly visible in the helmet, and I have also had keying issues with some test shots. There will be some lights within the helmet as well, but I don't think those will be enough. What can I do to reduce reflections both on set and in post?</p>

<p>I have read <a href="https://video.stackexchange.com/questions/15379/remove-greenscreen-reflections">this question</a>, but the only real answer was to use a polarizer, and I don't know how well that will work for me.</p>

<p>My editing software is DaVinci Resolve 15. </p>
