I have used light from below in many portrait photos. My images have been most successful when the lower light is filling-in the shadows created by the main light that is above the subject. Take a look at this photo (http://www.mindspring.com/~jwc3/kathrin1.JPG) to see what I mean. Look at the reflection in her eyes -- you can see the light from below. A lot of light from below can look more intimate, as if you're having a candle-lit dinner with the person in the photo. If I'm not using a light below, I usually use a reflector to fill-in the shadows.(posted 8975 days ago)
