This workbook is keyed to Henry Horenstein’s Digital Photography: A Basic Manual, 1st Edition. Mosley’s workbooks have been used since 1978 in classrooms or as self-teaching guides to strengthen one’s understanding of the craft of digital photography. Though the book is mostly comprised of questions to challenge the student’s understanding of the text, it includes assignments that may be followed for a semester course in photography. Designed to help students learn to read and understand a technical manual, these workbooks are useful, either for weekly assignments or as a supplement, to initiate discussions and pinpoint difficult concepts or techniques that need further attention. Try the workbook and see the difference it makes in your students’ understanding. And if you are an individual, follow the book and leave no stone unturned in your understanding of digital photography.
