By adding some artificial fog – we used a can of Atmosphere Aerosol – you can turn plain environments into dramatic stages, with shafts of light illuminating the areas around a model. All you need is a willing participant, a window with some direct light and harsh shadows, and the fog to fill it with. This technique works best indoors with no air movement, but if the air is relatively calm outside and you have the ability to generate a lot of artificial fog, you could get your shoes on and head into the open air.
