If you know very few of Photoshop,this is a good book for you.If you are an advanced user,trying to aquire new skills on BW processing,forget it. Most hints you will already know and there are even questionable techniques,(as converting from color to BW by RGB->Grayscale command,and not channel mixer manipulation or other techniques that can minimize noise channels).Did not fullfilled my expectations.
