 -- On 18 September 2012, Jeff Carlson is giving a free online presentation about the concepts and techniques in his book “ ” at 5:00 PM Pacific (8:00 PM Eastern). Over the course of the hour, he’ll demonstrate how to import photos wirelessly from a camera to the iPad, rate and tag images while still on location, edit the photos directly on the iPad, and more.
