Paul Gertman repairing musical instruments for high school students. I used 1 light for this image, a Ledgo Pro Series Daylight LED Panel 600. This was requested by the client who is a painter. Instead of using strobes, he wanted a constant light source to see how the light was falling on the subject. Nikon D750 with Nikon 35mm lens. Settings: 1/6 sec. @ f/11.0, ISO 1000. Camera was mounted on a tripod.
