That's when the idea came to me to make a mini studio. I'm very pleased with the results, although they aren't perfect so I wanted to share because I've never done it before.
It was pretty easy to set up. We drew the curtains and got a table lamp and angled it almost parallel but slightly away from the curtain, and positioned it quite close to the face. Then I put the camera on a fast shutter speed - 1/100 - for the chiaroscuro effect (although I'm not sure that was optimal). So simple!
