That happens to me a lot- I find that sometimes it's just a matter of playing with the basics to get it where I thought it should be- contrast, exposure, vibrance. But I think this is a fun half and half- me and my shadow!
Isn’t that the way it so often is? The idea looks amazing in our heads. The result, in this case, is a perfectly fine half in half. Given a choice between this and your granddaughter half and half shots, the girls would win hands down, but this is a nice addition to your monthly calendar.
