Comparison of Quality and Information Content of Digital and Film-Based Images
ISPRS Commission III: Theory and Algorithms, 2002
Digital cameras have started to replace analog film cameras for many applications. Considering the huge consumer market of small format cameras and compact cameras or the professional medium format or large format photography, digital senors are on the advance. The comparison between digital and film-based data is done taking into account photographic and photogrammetric issues. Not only radiometric quality, but also the geometric performance of digital and analog cameras are investigated. When trying to compare the quality and the information content of panchromatic digital images versus analog film, only a small amount of literature is available to brush up one’s mind. Encouraged by this situation, we have investigated different film types and a digital sensor and their output in order to better understand how to compare and to judge image data.
