I tried something different on a whim the other day, and I am pretty happy with the results. A friend of mine wanted to try something for herself and for her boyfriend. We used a lamp and a flashlight for lighting and one of my roommate's bed sheets. I am glad that I could give some confidence to my model and make-shift shoots are still my favorite. They force you to be creative at 11pm on a Wednesday.
P.S. I did get permission to post these.
