I bought this book because I was looking for some inspiration and info on techniques I could incorporate into my art sketchbook. Most of the techniques in this book involve taking a photograph and then altering it using different techniques such as monoprinting, bleaching, incorporating found objects, editing on your computer etc.
It's an OK book but I found the featured work to be quite 'same-ey'. Does give you instructions for specific projects but they appear clumped together in a single paragraph and are difficult to grasp (I found myself having to read the paragraph several times to understand the steps involved). I don't see why the author couldn't just break up the instructions by numbering steps instead of having them appear as one big chunk - it's quite off-putting.
Overall, there are definitely some nice things to look at in this book but it's a bit of a let down. If you just want inspiration from other artists (no techniques described), try 1,000 Artist Journal Pages: Personal Pages and Inspirations
which has a much better variety of finished work - there's examples of altered imagery but so many other things like illustration & mixed media work. As for finding a book that instructs well in conveying the art of altered imagery, I guess the hunts goes on for me.
