Once it got dark, we left the park and headed outside my studio. There I set up my fog machine and 2 strobes. The key light had my octagon softbox again. The backlight is where the magic happens for this though. I took my other strobe and put a gel on it and then aimed it at my subject. Once I laid down the fog like I wanted I’d take my subject’s picture. The light would hit the fog and light everything up and you get a really awesome shot.
It isn’t that easy though. Two things must be managed at the same time. First, your subject has to be between your light and your camera. That sounds easy, but remember, there is a wall of fog between your subject and that light, so it isn’t that easy to see. I ended up using a strip of paper to mark where I needed to stand.
The next problem was the fog itself. Once the machine puts it out, you need to move because even light wind will carry it all away. So, you need to figure out how much you want out and how much time you have once it is out. Now, I love my fog machine, but it is as cheap as they come, so it only puts out fog for about 10 seconds and then needs a minute to cool down. The short answer is you figure it out by trying it several times. Practice.
