The heat and humidity were intense, but fortunately I’d been to soul weekender events before so I knew that the camera body just needed time to warm up to room temperature, and I usually carried a couple of lens cloths, too.
Once the camera was ready to use I had to hope that they weren’t about to blast a lot more smoke into the room, and that the strobe light wouldn’t be on incessantly.
There was rarely enough light to focus, so I used white marker pens to highlight the 1m and 3m distance indicators on the lens, and if there was UV light, that worked really well.
