White canvas still at its temporary place, aka draped over a sofa back (hence photo of only a part of me) and i can't find my lightstand .. and this was the only "okay" photo.
Strobist info:
D90, sigma 30mm f1.4 at iso 500, f4
sb600 & sb900 on either side of canvas, pointing to the canvas at 1/16 power.
Dont ask me why iso 500, i forgot to change it and i was in a hurry =P
