In the above video I’ll show you how I use cinefoil to shape light with my small strobe light. Of course, you can use this stuff on just about any light you have. This stuff can be used over and over again, is pretty cheap to buy, and can be cut and shaped however you like. I use it to make a snoot, create slits of light, or make into square lighting for museum lights.
Check out the above video for a quick, three minute talk on how to get use it.
