Create atmosphere with a fog machine
1 Wait for haze
Initially, the smoke produced by an inexpensive smoke machine like this can be too swirly and active – but we don’t want it to look like the room is on fire, we just want a substance to the air. By waiting a few minutes for the smoke to settle, it hangs more delicately in the air.
2 Darken the room
The rays of light will only show if we’re able to create contrast between them and the rest of the scene. As they’re bright, we can create the contrast by making the backdrop behind as dark as we can. Block any other windows and turn off overhead lights so the ambient light is at a minimum.
3 Choose an angle
The angle for lighting is imperative. We need to think about where the light will fall, and how we can make our subject best stand out. Here a side-on angle works best, as it means the light falls across the dark backdrop and silhouettes them. If we’d shot straight-on, they’d be lost against the bright window.
