ABSTRACT
The management of digital images through an imaging chain is a complex operation. A hybrid imaging chain combines silver-halide-based processes with digital processes, for example scanning a photographic original which is then processed and output digitally. If the digital workflow is to adequately satisfy the needs of the application, then a thorough approach must be used, with thought given to the hardware settings to be used and the various image processes that may be applied in software. Changes in pixel count in digital systems are predominantly achieved by interpolation which may introduce digital artifacts into the image. When capturing images using a digital camera, the choice of input resolution will be limited and is unlikely to exactly match that of the output device. The Universal Photographic Digital Imaging Guidelines (UPDIG), produced by the UPDIG coalition, describes one of the aims of digital workflow as the preservation of image appearance as the image moves through and between imaging chains.
