摘要
针对演播室高低色温光源混合运用造成的混合光场景录制节目所表现出来的图像画面色彩还原不理想,混合光色温变化不均匀一致造成画面颜色偏色以及怎样把控好光圈曝光量的问题进行了浅析。通过了解所用光源的特性,利用雷登纸来改变不同光源的色温使混合光场景的色温趋于相对一致,通过摄像机白平衡等技术的调整和与多部门的配合,通过了解镜头特性、把控光圈曝光量的大小来获得清晰、柔和、富有层次感图像,这样在混合光场景中就可得到满意的画面。
Program image color rendilion is not ideal in hybrid optical scene caused by mixture uf low and high color temperature, the change of mixed light color temperature is not uniform causing the picture eolor east and how to control the exposnre of aperture, above problems are analyzed. Through understanding the characteristics of the light source, using the ration paper to change the differenl light source color temperature make the mixed light seene temperature tends to be relatively consistent, through Ihe camera white balance adjustment and such as the muhi sectoral cooperation, through understanding the characteristics of the lens aperture, exposure amount to get clear and soft sense image,satisfied pictures can be got in the mixed light scene.
