What DVShow said was right on. Essentially, the principle to get the silhouette shot is to underexpose your shot so the subject is black. Putting a bright background behind them is the easiest way to pull this off.
However, let’s say you want a dark silhouette AND a dark background. How do you do that? Glad you asked! 😀
To do this, you’ll need to be in a darker room. No windows (or heavy curtains) helps.
Your talent should sit on a backless chair or stool for this to work properly, but you can use a chair with a back if it’s very small and can’t be remotely seen.
On a tripod set up a few feet behind your talent, set up a light source, positioned very low, probably the same level as your talent’s lower back. If you’ve got barn doors to direct the light, it helps. (No barn doors? MacGyver something. I know you have cardboard and duct tape someplace in your home!)
When the light is on and properly aimed, it makes the silhouette of the figure well lit, but leaves the face and the front side dark. Adjust your iris settings to taste. Chill and serve. 😀
