Lately, I have been planning out a complete set of images before publishing the first one. Then scheduling them for one a day. There have been times in the past when I started on something, and then midway through changed direction. It is not a big deal, but I like to create the illusion that I am more organized than that.
These are work in process. I am not certain where this collection is headed.
