This article focuses on the “China Heart Games Love” celebration of light television production, which includes mobile studio and part of the main venue of the two sites.

Mobile studio Broadcast throughout the festival from 16:00, until 22:00. Thus, from day to night, shooting the scenery (host, Riverview) there exists in the natural light to the lighting transition. Under these conditions, lighting production to solve two problems: (1) under different color temperature of light (from natural light to the lighting), how to maintain the consistency of image color reproduction; (2) how to handle the host and the Pearl River Lighting Night (cross lighting) than light. The former can be preset by the camera’s color temperature function to solve, that advance will be shooting natural light and artificial lighting conditions, adjust the white balance data stored well, and then be converted according to lighting conditions in a timely manner. For the latter, if the illumination of the host is too high, the camera’s aperture will be reduced, this time shooting pictures of Pearl cross neon lights will be the lack of hierarchy, even darkness; on the host if the illumination is too low, then again can not meet the minimum illumination requirements of the camera, if you open the camera gain is taken, then the increase will inevitably lead to clutter the screen image.

Order to highlight the beautiful night view of Pearl River, Pearl River bright lights for the host against the background presented in the audience, must fully take into account the illumination and the Pearl River hosts the balance of light intensity. We selected two Lowel4X55W Tricolor soft light as the host of the surface light, illumination for the 450? 50Lux; with a 1kW film spotlight as the host of the backlighting, illumination 500Lux. Overall intensity of illumination required to meet the basic camera, the camera aperture F = 4.

Pictures from that night to see live, cruise ship host surface light soft, panoramic view of Pearl River night also.
