If you have access to a studio, an unlimited amount of playtime and more lights than you can count on one hand don’t worry too much about checking out this site… http://www.zvork.fr/vls/
For the rest of us this might just be a good way to practice positioning lights, in a consistent manner, just to see what happens in those “I wonder what’ll happen if I put a light here?” moments. With up to six available lights, a range of modifiers, coloured gels, and the ability to alter the power of the lights you have plenty of scope to muck about. Okay so the model can’t look around, and the lighting positions are a bit limited – but if you want a quick way to check out lots of lighting styles this may be a help. It’s also a bit of fun too.
