Sometimes I take a photograph with the intention of using it for this project. But on days when I'm taking pictures anyway, I often assume I can find one to use. Sometimes that requires altering the original to create some blue. In this case, I include the original because I like the greater level of detail and texture, and besides, "Before and Afters" are always fun. If you're wondering how I got this effect, I used the "threshold" feature in my photo editing program.
