Image Presentation

Abstract

Appropriate display and hardcopy are as important to proper interpretation as any other part of the imaging chain, and any degradation in their quality will prevent optimisation of the imaging process. Photographic film was the traditional hardcopy medium; originally being used to accumulate counts during an acquisition to create an analogue image and then subsequently being used to record the results of a digital acquisition for interpretation. This is, effectively, becoming obsolescent. With digital acquisition becoming almost universal, hard copy is increasingly being produced by networked digital printers of various kinds and much interpretation is being undertaken directly from the display. This requires the digital data to be translated into colour or monochrome representation and this must be chosen carefully, particular translations suiting certain data and others degrading the representation.
