Modeler's Moment - Check your white balance

This tip could go just as easily under lighting as it could under model photography. Be aware of what kind of lighting you're using on your layout. In the same way that incandescent bulbs can cast a yellowish glow, most of the fluorescent bulbs will have a green tint to the light that they give off. When you're painting your models, paint them under the same lighting conditions as your layout. If you're photographing models, check your camera's manual on how to set a custom white balance to compensate for it.
