A square composition for this shot. I think I have to experiment a little more with the idea of creating a corner in the background, because I really like the effect.
For this shot I used a side light with soft box and two canvas to create a corner behind the subject, then I placed a black board on the left and on top to darken some areas on the background. I also used a small sheet of paper to reflect just a little bit of light onto the subject and the spoon (on the right).
