This is one of the clearest, best laid out, accessible and well illustrated photo books I have yet seen as an eBook. The book is devoted to the use of the Nik imager processing software for black and white images. If you are serious about this you will acquire (or already have) this software. If you place the image processing on the left of your screen and open Whalley's book on the right-hand side (or on your Kindle (eReader)) next to you; you can go through the book whilst editing your own image. There is no better way to learn. This book is a must for all photographers working in monochrome with this software.
