Top: I was attempting to create an image in which I appeared to be a translucent ghostly figure by moving during a long exposure (an example of intentionally doing something which could be considered a photographic error) but unfortunately I set the focus on me rather than the wall behind me as I should have done. I think the resulting image is interesting, but is also an example of both intentional and unintentional errors in one image.
Bottom: This photograph was taken whilst my camera was on a timer, continually taking photographs whilst I prepared for a self-portrait. It was a fairly long exposure so I appear blurred and, in my opinion, I look a bit like a penguin. The photograph was taken basically accidentally, although I have taken a little time to improve the raw image and make it look more penguiny.
