We had a specific design for the light — 18 strobes. That’s a lot of lights. A lot. Because we were shooting at, like, f/64. It’s very stopped down, with an 800-millimeter lens — sometimes 600, but mostly 800-millimeter. You have very little depth of field, so you want it to be stopped down as much as possible.
Oooof! Talk about power!
