This blog is my toy box. As I shoot pictures, there are typically dozens to hundreds of photos on the card, depending on the excursion. Many are similar shots, playing with slightly different angle or camera setting, and working on exposure or focus. Most of the shots get dumped after a cursory look. I'll admit, it's not great writing, but I plan to work on that as I continue forward.
Those that do get to stay in my hard drive are generally not quite up to the standards I want in my portfolio. So the blog is a place I can put those photos and if appropriate, tell a story about them.
Facebook and Google+ get the bulk of my photographs, but there are some with a story that usually involves a learning experience for me that occurred taking the photos.
