I was lucky to be involved in a project working with the boutique cocktail bar The Hold in Manly (in the Northern Beaches of Sydney, Australia). The project was to shoot staff portraits with a dramatic theme to match The Hold's interior theme of the hold of a ship.
I shot mostly with gridded diffusers mixed with the ambient lights in the bar and in some shots used canned fog spray to create a dusty fog look in the background of the shots. I shot on a Canon 5D Mark IV tethered to a laptop using Capture One Pro.
If you're in Manly I'd recommend checking them out as they're an awesome bunch of people.
