for my test today WandW i'm using no raytracing, i'm using a real mirror, real lights and a real human to see what real world effects are, i thought that might be the best place to start before I set up the scene and assume what results I should achieve, this working on the principle that the op wanted to achieve real world results, which actually might not be what he was trying to achieve, as many people go for what looks good and works within the confines of the scene  as opposed to what is photorealistic....
