I placed it on top of a CD, simply because I wanted some form of placeholder, and the CD worked perfectly, but the reflective imagery from the CD also ended up adding a nice touch to the photo. From that angle, and the silver of the CD, it also makes the egg look like a light-bulb of sorts. I also placed it in a position where the lighting ended up being in a line over the egg, connecting the top and bottom of the photo, with the egg as the center. I took a different bunch of photos, from different vantage points, some with other backgrounds etc. I liked this one the best simply because it was clean, simple and the lighting was better.
