Series of altered photographs
The only quality a UFO, an Unidentified Flying Object, has apart from the fact that it is flying is existence. We know THAT it is, just not WHAT. If we could identify the UFO it wouldn't be one anymore. A photograph of a U(F)O is a photograph of something that exists, nothing more.
The photographs in this series are what might be called "authentic' UFO photos" taken in different places from 1949 until 2004. They are altered with the aim to enhance their appearance as existing. Instead of trying to reveal the UFOs "identities" their actual identity as unidentified is strengthened.
