Yesterday I came across a tutorial for how to create shapes out of bokeh (the blurry bits in the background of your pictures when you have a short focal depth) and I decided to try it out on our Christmas tree.
The tutorial is here. I love the way it turned out!
All I did was cut out the shape I wanted to make out of dark colored construction paper, and then I just held it up to the front/center of the lens of my D50 and manually blurred the focus with the camera at the widest (lowest) F-stop. Easy peasy.
These are my little cutouts:
And, for good measure, I also got a picture of Bobo with heart shaped bokeh. :)
