I am filming a scene inside of a warehouse where it will have basic lighting.

There will be a huge 15x15ft glass, plexy glass or something for the 2 actors to write on with a silver pen. In the end it will have the whole 15x15ft glass filled with writing.

My main question is how to not get reflection of the lights on the glass. Is there a type of glass that reduces reflection? Since the key light might be passing threw the glass.

Is there a glass that is great to write on and erase? We are getting 2 pieces just in case something happens to the first.

Also getting the cameras reflection, since alot of it is looking straight on. Is it just as simple as just blacking everything out behind the glass?

I attached a reference pic that i got off the internet.

No special glass needed (or affordable anyway at that size) just black everything off that the glass is facing -- think big.

I'd add that if you were going to use a top soft light for the key but semi-frontal, so forward of the sheet of glass, it would help if the glass was slightly tipped towards the camera to help keep overhead lights off of the reflection. To some degree, the white cyc background will hide a lot of reflections except the area of the frame containing the darker clothes of the actor.

Yeah i was thinking of turning the glass to hide the reflections a bit. But there will not be a white cyc background. It will have a warehouse look that falls into blackness. But the only thing to do is move the glass and the camera to the correct angle to hide reflections. Possible put a polarizer on? Thanks for the responses!

Pola won't do much if the camera is mostly flat-on to the glass, only if the camera is at a 45 degree angle to the glass.
