There are photos that we take and fairly often agree that these appear to be mistakes. They are abstract, and upon first review one could easily discard them. This is what I envision people may say that are accustomed to formal photos that are clearly defined.
The set I have here is a sample from various locations, times, and cameras. They are accidents, wonderful accidents of course because I took them! If I think about some of them I might discard them, and then on second thought keep them. So why don't you decide on which ones you like, why, and let me know.
