数字影像是整个摄影领域的一场技术革命。它最显著的特征是影像成像核心方式的变革,即数字编码成像替代化学银盐影像。不仅如此,重要的是数字影像产生了一系列新的摄影技术用语、方法及技术标准来控制影像品质,形成数字影像的技术体系。同时数字影像的技术手段也带来了摄影方式及视觉文化传播的新特色。摄影产业是研发数字影像的重要推动力,同时也在这场摄影技术革命中承受着颠覆性的变革。在新旧技术的较量过程中,大型摄影器材企业全球大洗牌,新兴摄影产业应运而生。但是在这个栏目开始之初,我还是想先告诉大家,数字影像存在三个不可回避的缺陷。
Digital photography is a technological revolution throughout the field of photography. Its most notable feature is the transformation of the core imaging imaging method, that is, digital coding imaging instead of chemical silver salt imaging. What’s more important is that digital imaging has produced a series of new photographic techniques, methods and technical standards to control image quality and form a digital imaging technology system. At the same time, the technical means of digital imaging also bring new features of photography and visual culture. The photographic industry is an important driving force behind the development of digital imaging and is also undergoing disruptive changes in this photographic technology revolution. In the contest of old and new technologies, large-scale photographic equipment enterprises reshuffle the world, emerging photography industry came into being. However, at the beginning of this section, I still want to tell you that there are three unavoidable defects in digital images.
