From the Richard Curtis Blog at Adobe:
There is a new free iPad app in the Apple App Store based on the Adobe Digital Publishing platform. This great app has been created by Canon and goes in the whole Canon camera eco-system. It’s got a wealth of content and interactivity, including which lenses to use for what style of photography (Macro, Wedding, Portrait, Food and many more), tips and techniques when using the Canon EOS system, but also interviews with leading Canon Ambassadors and Explorers. The app is available here in the Apple App store, and is available in EMEA only.
