One of my most useful buys as a beginner in graphic design and new to the Adobe Creative Suite. This book has been great for me. Clear overview of key concepts and ideas with loads of pictures of exampes. Helps a novice unpick what they are looking at an recognise all the decisions a designer has made.
Don't be put off by the plain cover - the inside couldn't be more different! Well produced and visually engaging.
The exercises to introduce you to Adobe tools are useful. Be warned the instructions are brief and if you are learning in isolation (as I am - filling time while stuck overseas) you may want to buy other books to help you. But between these exercises and online tutorials you can made some headway with Photoshop, Indesign and Illustrator.
While I have used the software exercises, I have been less disciplined about doing the design practicals as I have other distance learning assignments - but I think that has been to my own detriment and I intend to go back and work through them porperly.
Suspect it's going to remain a useful reference for a long time to come.
