Hi, folks. So my new book on EOS flash, Mastering Canon EOS Flash Photography, is about to be released, and I'm going to be doing some free talks in Seattle, Vancouver and London over the next few weeks. The talks are going to be about getting started with flash photography, and will be system-agnostic. Seattle, USA: April 21 Vancouver, Canada: April 24 London, UK: May 10 More details at: http://photonotes.org/blog/?p=285I'm also holding a totally free prize draw for a copy of the book. Thanks!
