This is definitely one of the weirdest places I have ever shot in.
This shot of the cosplay actor in the Penguin role was shot in an old abandoned building that once housed a high-tech company. Deep inside the building was a sound-deadening anechoic chamber with most of the sound deadening foam blocks still in place. There was a tiny platform to put my flash stand with octabox.
Did I mention it was around 35°C / 95°F in the room? Also it was pitch black so I had to shine a flashlight on the subject to get the camera to focus. It was almost freaky to shoot in a place where the sounds were all swallowed up.
I still have some work to do, but I like the way it is coming.
