数码分色照相的方法与应用分析

根据数码照相机拍摄图像的成色原理，利用Photoshop 7．0图像处理软件对数码图像进行通道分离。说明在RGB3个通道分离后的灰度图像与传统分色照相中使用三原色滤色镜拍摄所得的照片在分色效果上基本相同．并通过试验结果加以证实。由此可见，在数码分色照相中无需使用三原色滤色镜。同时指出，使用其它颜色的滤色镜进行分色照相，数码与传统的方法相比，它们在分色效果上几乎没有区别。

Method of Digital Color-Separation Photography and its Practical Use Analysis

According to the color formation principle of digital cameras, applying Photoshop 7.0 image editing software to spht the images into three channels, the gray images after RGB split channels are almost the same as those created by the traditional color separation photography by using three primary colos filters, as verified by the experiments. It is therefore not necessary to use tricolor filters in digital color separation photography. It also indicates that in color separation results, there are almost no differences between the digital color separation photography and the traditional one when using other color filters.
