Chase Jarvis gave the keynote at PDN PhotoExpo in NY in October. The video of the presentation is available here (I don't know how long this link will work, I recorded the audio and will post if they take the video down). Jarvis is a well known Seattle-based photographer who is taking professional photography is a fresh new direction, and he encourages all of us to unleash are creativity everywhere through everything you do. He shares his inspiring work and creative projects liberally on the web through his blog and videos. "A creative world is a better world."
