计算机和网络的使用越来越多，导致图像沿着新的路径传播。摄像机拍摄的图像将被打印出来；医用x射线被发送到视频显示器等。所有这些都需要重新思考效率和有效性问题。如果我们不确定图像要去哪里，我们如何设计合适的格式来传输数据？一个立即浮现在脑海中的答案是使用标准颜色空间传输图像。选择合适的色彩空间并非易事。1999年，国际电工委员会（IEC）首次尝试用其sRGB颜色编码来回答这个问题。这产生了一种编码，用红色、绿色和蓝色设备控制值表示典型阴极射线管（CRT）的色域。 虽然这一空间在许多领域被证明是有用的，但它并不适合所有用途。许多人认为需要一个覆盖比CRT更大色域的标准颜色空间。因此，2000年11月11日，CIE举行了一次关于扩展范围彩色编码的专家研讨会。来自标准机构、学术界和工业界的专家作为特邀发言者，讨论了数字摄影、多媒体、平面艺术、彩色和互联网传真、电视和数字电影的扩展范围彩色编码。发言者介绍了需要解决的问题、解决方案的标准以及提出和开发的空间。演讲结束后，进行了一次公开讨论。这些会议记录包括发言者提供的文件和公开讨论的记录。 该出版物共93页。

The increasing use of computers and networks is causing images to travel down novel paths. Images created by video cameras are going to print; medical x-rays are sent to video displays, etc. All this creates a need to rethink the issues of efficiency and effectiveness. How do we design an appropriate format for transmitting the data if we are not sure where the images are going? An answer that immediate comes to mind is to transmit the images using a standard colour space.The selection of an appropriate colour space is no easy matter. In 1999, the International Electrotechnical Commission (IEC) made a first attempt at answering this question with their sRGB colour encoding. This produced an encoding that represented the colour gamut of a typical cathode ray tube (CRT) using red, green and blue device control values. While this space has proved useful in a number of areas, it is not adequate for all purposes. Many people perceive a need for a standard colour space that covers a gamut of colours larger than that of a CRT.Accordingly, on 11 November 2000, the CIE held an Expert Symposium on Extended Range Colour Encodings. Experts, as invited speakers, from standards bodies, academia and industry discussed extended range colour encodings for digital photography, multimedia, graphic arts, colour and Internet facsimile, television and digital cinema. Speakers described the problems to be solved, the criteria for solutions and what spaces have been proposed and developed. After the presentations, there was an open discussion session.These Proceedings include the papers provided by the speakers and a transcript of the open discussion. The publication consist of 93 pages.
