Loop Lighting

Well. This was an assignment in portrait lighting, to get us to use loop lighting. (notice the "loop" below the nose) and along with that we had to use different light size ratios. 1:1:1 is when you are framing your subject in your camera at about .5m and are about .5m away from your subject, and when you have a light aprox .5m Sq. 1:1:4 is with the light twice the distance. and 1:1:16 is with the light at lwice the distance again! and the 4:1:1 is with a light about 2m sq. and about .5m away, with a .5 framing. :)
So much fun eh? :) it helps give me an idea of how light works though...
