Working a collection of images into a refined project often involves trying to identify those images that are odd ducks, that is, the ones that just don't seem to fit with the rest of them as comfortably as they should. It might be a matter of content, it might be a matter of composition, it might be a matter of any number of factors. The challenge is to find those odd ducks and decide if they're out because they're odd, or in because they make an important contrast to the rest of the images.
