Michael Peres is the editor-in-chief of The Focal Encyclopedia of Photography, 4th Edition, and former chair of the biomedical photographic communications department at the Rochester Institute of Technology. Since 1986, he has taught photomicrography, biomedical photography and other applications of photography used in science. Prior to joining the RIT faculty, Peres worked at Henry Ford Hospital and the Charleston Division of West Virginia University as a medical photographer. He is the recipient of the RIT Eisenhart Outstanding Teaching Award and the Schmidt Medal for Lifetime Achievement in the Field of Biocommunications.
"The book is both comprehensive and accessible to photographers at all levels. Each topic is approached without expectation of previous knowledge from the reader or any photographic snobbery. For example, whether you are reading about comparisons between focal plane, sync speed, leaf and electronic shutters or how to apply an un-sharpen mask in Photoshop, everything is written in an easy-to-digest way for photographers of all backgrounds. [It] provides theoretical content to underpin many of the day-to-day practices of a medical photographer. Other practising clinical photographers will find the book reaffirms much of their current knowledge, while enhancing their understanding in some areas and potentially providing an introduction to unfamiliar techniques. The underlying feeling I had throughout reading this book was `why couldn't this book have been available while I was studying?' I will certainly be using the book as part of my continuing professional development for many years to come." -Simon Brinkworth, Medical Illustration, Marlborough Hill Workshops, Bristol, UK (c) 2018 The Institute of Medical Illustrators
