Today I was shooting at a crossfit my friend was competing in. I was not an event photographer, just shooting from the spectator area. The building this event was held in had a tall ceiling, which was painted black, down to high point on the wall. I saw one of the two hired photographer/videographers, using what looked like a costly Nikon rig, trying to bounce a bare flash off of said ceiling. All of light from his speedlight was going up and disappearing. I was just shaking my head. This same guy also flew his drone into one of the hanging light fixtures. The drone was caught up in the light and cables which held it long enough to damage the drone. Again with my head shaking.
