This book is extrememly well written and easy to follow. I always thought I didn't need this book because it was probably just for people who are into messing around with raw chamicals. How wrong I was. It really adds a new dimension to your traditional monochrome photography when you understand what is in the various developers, how they work and the history behind them. It really is not complicated, and you definitely do not need to be a chemist. And, infact, neither do you have to be into mixing your own formulas to need this book (although you might start wanting to anyway) because its key objective is to address how different developers and chemicals are used to control and achieve the results you are after from your photography.
On top of this, it is now bang up to date having been revised in 2008 and therefore it takes into account film brands such as ADOX/Efke which have become more prolific in recent years, plus other current products and developments in the industry. Further to this there are contributions from other photographers.
