Acknowledgements
Writing this book was a collaborative effort and we are indebted to the expertise and aid of several people who helped bring this book to fruition. Thanks to Scott Dordick, owner of Acratech, Inc., for his assistance and discussions about using tripods in photography. Also, thanks to Matt Cardwell of Cognysis, Inc. for his guidance about focus stacking and the applicability of the Cognysis’ ShotStack, a program for extending the depth of field in our scientific and close-up photography. Both Scott and Matt provided product shots of their accessories for this book. In addition, we thank Sony for allowing us to use their product shots of the Sony a7 and a7R.
Last but not least, thanks to the staff of Rocky Nook. We are indebted to Gerhard Rossbach for his guidance in putting together our books, and to Joan Dixon, Managing Editor, and Matthias Rossmanith, Project Manager, for overseeing our efforts and the efforts of Maggie Yates, Editorial Assistant, and Jan Marti, layout artist, for formatting our book.
It is a major benefit for us to have an opportunity to work with such a wonderful group of people.
