ABSTRACT

Sensitometry is the science of measuring the sensitivity of photographic materials. It is commonly used to illustrate the characteristics of film and paper, whereby the image density is charted in relation to different amounts of exposure and the processing of these materials. The practical photographer has often little or no ambition to learn sensitometry, but a fundamental knowledge of this potentially complex technical field can be very helpful to understand how different films and papers respond to exposure and development variations (fig.1). This introduction will familiarize you with the basic terminology and introduce you to film and paper characteristic curves as they frequently appear in manufacturer’s material specifications and photographic literature. The practical photographer is usually not interested in sensitometry, but it does reveal how films and papers respond to exposure and development. https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9780240816265/ffb21561-2f2c-4dca-99ec-f086fc154d4d/content/figch4sc2_1_OC.jpg" xmlns:xlink="https://www.w3.org/1999/xlink"/>
