ABSTRACT
Throughout this book, we suggest modifying the film development in order to control negative contrast, but we always imply that print development is a constant. Some printers change the print development for creative purposes, but we accomplish our image manipulations during the print’s exposure or through post-processing techniques and, therefore, prefer to keep the print development consistent. The main process variables of film development are easy to control, but the actual print development constantly varies due to continual changes in developing activity, caused mainly by temperature fluctuations and gradual developer exhaustion. One strategy to compensate for constant changes in print developing activity is to modify the print development time accordingly, which has advanced into an efficient technique referred to as ‘factorial development’. https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9780240816265/ffb21561-2f2c-4dca-99ec-f086fc154d4d/content/figch47_u1_OC.jpg" xmlns:xlink="https://www.w3.org/1999/xlink"/>
