Photo-Noir is a beautiful style of photography which can be done anyway with a single light source...
The images below were shot in my living room with a small black cloth background and a single studio light with a small softbox.
The light was placed at 45 degrees to the subject and about 2 feet away, giving a very soft spread of light.
They were shot at 1/200s F8 iso100, then converted to black and white inside of photoshop.
I hope you like them.
