Here is the portable portrait studio set up in the bedroom. I am using the Lightsphere flash diffusers and the wireless pocket wizard. I used a set of umbrellas in a later set up. The good thing about using the flash units is that I already had them. The bad thing is that they don't put out enough energy to be very effective with the umbrellas. I can go to ISO 400 which improves things considerably. That is certainly doable with my Rebel XT since its noise at 400 is quite acceptable.
