Laura Blacklow's New Dimensions in Photo Processes (4th Ed.) is an excellent step by step manual to a great number of alternative photographic techniques. It covers not only the basic commonly used techniques (solvent transfers, Polaroid transfers, cyanotype) but many lesser used processes (bromoil printing, contemporary daguerreotypes, etc.) I own a number of other artist written technique books and have not found one that is more comprehensive, organized or easy to follow. The book is well illustrated not only with engaging examples of artwork but also with excellent step-by-step photographic illustrations of the various processes. If a technique requires work with a computer (e.g. making a digital negative), Blacklow has included images of the computer screens involved and walks the student through the processes with step by step instructions. With techniques using hands on chemistry, safety issues are appropriately considered and addressed. It is clear that Blacklow has considerable knowledge of both the chemistry and computer skills involved. I am an artist who has worked considerably with non-photographic printmaking techniques and have minimal experience with the processes covered in this book, but feel confident that I could follow this book's directions and successfully learn any of them. Bravo--five stars and more. . .
