It's like you're making a laser beam.
It is like a laser, yeah. What happens is that if you're really close to it, but you're off-axis, you're just getting a little bit of spill. If you're really far away, but you're right in the focus of the beam, you're still getting the same meter reading. I've done it before--not with 3,000 people. But, to me, that reflector is like the secret weapon in the Profoto lineup. It's an amazing tool.
