I have an upcoming shoot where I want to cast some light through a window to crate a shaft to look like it's coming from a street lamp outside. The windows are quite small (about 5ft tall, 6ft wide) and are frosted with a texture to them. I'm worried about how well the light will travel through them as I don't want it to just distort and glow, I'm after more of a shaft to give us some background and bring the night light into the room.
I'm planning on using a 1.2 HMI and rigging it high outside with some atmos in the room, does anyone have experience with this and know if the frost might create problems?
Thanks in advance!
