Last time this picture was deleted as it lacked a proper description of a setup.
The animated gif I'm showing now is still not what Strobox's community is used to, but I believe this is the best way to explain what was going on during the shoot.
I was lighting the gear piece by piece with a gridded flash, and then blended all the exposures together.
I guess a picture taken with this technique hasn't ever been uploaded here, so I insist on not removing it again.
