The Still Shadows

I bought one Flash Remote Generator two weeks ago, one is generator which will be installed on the hot shoe of the digital camera. Another is receiver which will be connected with flash (I am using the Nikon's SB600). I build up my tiny studio with two flash and one piece of black background.

I took some pictures for my girl last weekend by using this studio. You will find some problem relative with lights, because it's hard to control the output level of the flash.
