Sensitometry" is a term that was created by combining the words "sensitivity" and "measurement". In the film camera era, a densitometer and other equipment were required to monitor the color temperature and brightness of the light source, exposure time and conditions, developing time, and film image density, equipment that most people did not have. With the dawn of the digital camera age, however, image editing software has created an environment in which just about anyone can measure shooting conditions. Here we will explain how to use a digital camera with a light meter to obtain good photographs and provide an understanding of some of the thinking behind sensitometry.
