我们拍照时,除非要营造一些特别的气氛,一般都是要求影像的色彩能与被摄体的原有色彩一致,即色彩重现要准确。对于使用数码相机的拍友,要拍出准确色彩,便要利用相机的“白平衡”色彩修正功能,除此之外,也可利用影像处理软件的色彩调整指令,来修正影像的色彩。 一、影像偏色的原因 白光,是由很多不同波长并按一定比例的色光所组成,它是所有色彩的来源,没有它,便看不到物体颜色。当白光照射到物体表面,物体对它会有以下的特性:吸收某一部分波长的色光,并反射或透射其它波长的色光,而反射或透射出来的
When we take pictures, except to create some special atmosphere, usually require the color of the image can be consistent with the original color of the subject, that is, to reproduce the color accurately. For those who use digital cameras to take accurate color, they have to use the camera’s “white balance” color correction, in addition, you can also use the image processing software color adjustment instructions to correct the color of the image. First, the reasons for image color cast white, is composed of many different wavelengths and according to a certain percentage of shade, which is the source of all colors, without it, you can not see the object color. When the white light shines on the surface of the object, the object will have the following characteristics to it: absorbing a part of the wavelength of the light and reflecting or transmitting other wavelengths of light, and reflected or transmitted out
