Absolutely brilliant, I simply do not have time to attend a training course but really need to get to grips with Aperture 3. This book and accompanying DVD allows me to do just that in my own time and at my own pace. It is well written/illustrated and I have finally begun learning in a coherent and logical way. After spending many weeks gathering disjointed and sometimes inaccurate information from the internet this is a welcome relief. If you have already paid for Aperture 3 then the small extra price for this book will really help you - worth every penny!
