My mom wants a photo of my sister and me for christmas. I was thinking that I could do this, but I dont know where to start. I dont have a studio, and I dont have any advanced lighting, only a D40, and an SB-600. Do you guys have any tips for this? Should I even attempt to shoot us, or should I just go to the pros? I cant really do antyhing outside, seeing as how its like 25 degrees and snowy. I'm kinda at a loss here.
