Photos should have a theme of street photography. Street photography is a genre of photography that records everyday life in a public place. The very publicness of the setting enables the photographer to take candid pictures of strangers, often without their knowledge. Street photographers do not necessarily have a social purpose in mind, but they prefer to isolate and capture moments which might otherwise go unnoticed. Because the images are captured in public places, many photographers try not to shoot people who are obviously weak, particularly vulnerable or otherwise compromised. Perhaps a useful guide to the ethics of street photography would to empathetically imagine the positions as being reversed: “How would I feel in this person’s shoes?” If the photographer would be upset about having an image of him/herself captured and published, that photo opportunity would best be let go.
