Paperback. Etat : New. Print on Demand. This book delves into the topic of photographic sensitivity, an essential aspect of photography. The author explores the varying characteristics of different emulsions and presents three methods for quantifying their sensitivity. These methods are analyzed and compared, with the author highlighting the strengths and limitations of each approach. The book emphasizes the importance of considering the entire sensitivity-development time curve rather than relying on a single numerical value to accurately represent an emulsion's sensitivity. By examining the relationship between sensitivity and contrast, the author demonstrates how the choice of minimum useful gradient can impact the resulting sensitivity index. The insights provided in this book are valuable for photographers seeking to optimize their techniques and for researchers interested in understanding the fundamental principles of photographic sensitivity.
