Task: Sentiment Analysis
Input (English): This book is very detailed, technical and complex. If you're seriously considering exploring the photogravure technique on copper, this book is a must. It tells you everything you will ever need and all the complicated steps in the process. However, there are few historical or contemporary photogravure reproductions which is why this book gets only a four star rating from this reviewer. If you are seriously considering the photogravure process as one you would like to explore, I recommend starting with solar plates rather than copper. It is much less complicated and toxic. A very good resource is "Printmaking in the Sun" (2001) by Dan Welden, inventor of this method.
Output (English): Positive
