At this year’s Macworld/iWorld in San Francisco, our own Jeff Carlson will be giving a presentation and hosting two conference sessions on photography. He chats with Chuck Joiner of the MacVoices podcast about them and gives a preview of what he’ll cover, including topics related to his “Take Control of Your Digital Photos on a Mac.” follow link
