Instant film is a long-time favorite; a marvelous ability to saturate, soft edges, solid tones. During a time in which I was focused on creating work that was, in one way or another, conceptually adversarial to technology, I began using instant film to create completely un-focused color fields, using the single frames to form larger compositions.
Just as with ...You Were Looking Away, using the film camera for what it is not designed to do can produce fascinating results. These color fields are immensely powerful in their own right, but their actual physical presence is relatively insignificant. That's gotta be a metaphor for something.
