I have been interested in photography all my life and remember quite well developing my first black and white films myself... My favorite subjects are...
I used to suffer from migraines. They are hard on you! Mine usually had me in bed, sitting up straight, room dark, for hours until it passed. I couldn't move or my head would throb. I do hope your walk helped yours to subside. You managed to get an interesting shot off though. Your ghosts are very interesting!
