I'm a big fan of using bead board as a bounce material, but sometimes it can be difficult when the gaffer in a new country doesn't know what a bead board is.
Sometimes, the material I end up with is a different, harsher material, which renders light less soft.
So, I was hoping someone in here could help me clear up my confusion between the many names,
Is there anywhere I can read and get good information about the difference between the following?
-- expanded polystyrene
-- extruded polystyrene
-poly (I'm guessing it is short for polystyrene)
Any help would be much appreciated,
