Chase Jarvis has a 60 second portrait, but for me that is too long. Some other film-makers have variations on the theme. It’s been used countless times in ads etc. As a portraitist, I really do like the 30 second “exposure” one has. It’s a portrait, but a bit more.This is Neil Stemmet.30 Second Portrait: Neil Stemmet from Danie Nel on Vimeo.Watch this space.
