I helped on crew a couple weeks ago for a Funny or Die video. I had originally agreed to be the AC and work the slate, but got bumped up to AD, yay!
At the time I didn’t have a slate, but figured I could make one out of materials that I’ve liberated from various classrooms.
What I used:
White erase board
An empty box of chocolates to provide back support (can’t really see it in this photo as it’s taped to the back of the board, but giving the board more depth made it easier to hold)
If I had more materials I would have made a better clapper portion with proper calibrated colors. Next time.
