Stage LED display and lighting perfect combination
Stage LED display and lighting perfect combination
In recent years, LED display technology has been developing rapidly, and the technical level and maturity of LED display equipment are getting higher and higher, and the fields and contents involved are getting wider and wider. On the stage of TV cultural programs, represented by CCTV Spring Festival Gala, the most dazzling should be a variety of LED display screens. They are based on a variety of carefully crafted pictures and dynamic video images, from the stage of the up and down, left and right, nearly seamless splicing in all directions, forming a near-perfect stage space, supplemented by hundreds of mechanical lifting the stage, it is the design field of the creative staff by the original stage on top of the stage to further expand the stage, the real stage points, lines, surfaces, etc. have become the display of the stage Artistic components, together with the Augmented reality technology, for the audience to create a real and unreal artistic atmosphere, visually give the audience a great impact and enjoyment.
However, the large-scale application of LED large screen for stage lighting art also brings some adverse effects. LED Controller summarizes these adverse effects, and find out how to reasonably use the LED screen, so that the perfect combination of lighting and ED screen, complement each other's methods, and really achieve the perfect combination of stage LED display and lighting the beauty of the design.
Unfavorable impact
(1) Now a lot of evening party stage to some extent is a big box will be illuminated, the brightness of the high (although adjustable), the color temperature of the high, colorful is the former WEI have. Stage light, especially the character's face light is more difficult to integrate with it, often due to the background is too bright and too prominent, making the appearance of the character's face is not enough illumination, gray, the picture is not transparent situation.
(2) The traditional stage, choreography set left behind by the empty black part of the lighting to be responsible for the further creation of the play, or bright or dark lighting and bright set modeling is formed between a combination of real and virtual, mutually beneficial and complementary relationship between the point and the line all the way to the surface, the spatial sense of the full. On the contrary, some of today's evening party stage, almost all the corners are LED display, although the picture is very beautiful, but give a person's feeling too “full”, too “blocked”, and even give a person a sense of oppression. And once some of the picture is a black background, it did not give the light to leave enough space and position to make up for the empty black. In a sense, this itself violates the laws of choreography.
(3) LED screen pattern is often with the computer lights beam, pattern, color is in conflict, and the current practice of CCTV to see, basically the lights sacrificed their own effect to ensure that the LED screen.
Solutions
First of all, to change the lighting design concept
Traditional television lighting production, reflecting the contrast between the brightness of the object, the camera will be photographed by the brightness of the object is truly restored; illumination and contrast to meet the requirements of the screen level, color tone, clarity can achieve satisfactory results. The LED big screen as the main background applied to the TV variety show evening after the lighting designer in the design, it is necessary to take into account its self-luminous properties, depending on its a large LED lamps and lanterns, because of its video content display of the different, its brightness, color also has different changes, without affecting the choreography effect and to ensure that the basic illumination under the premise of constantly adjusting the layout of the lights, not only to rationalize the use of light brightness, Light ratio, control the actors and actresses characters, scenery levels of contrast, but also need to actors and luminous LED screen brightness balance, master the stage of the overall color changes; so that the color temperature tone of the evening lighting and the content of the harmony and unity, so that the MAPP luminous LED screen is fully integrated into the TV stage, and TV lighting as one, so that the TV screen to get a true natural color reproduction.
Secondly, to adjust the light ratio, aperture, color temperature, video
Dimming ratio can be increased by increasing the brightness of the characters in the stage performance area or reduce the brightness of the large screen method to narrow the face and background light ratio.
Setting the aperture
During the actual recording of the rehearsal, the lighting technician and video technician will first determine a basic aperture range according to the program form, this range should always ensure that the camera is in the Z best working condition, i.e., between F4 and F5.6. In this aperture range to complete the basic lighting required by the camera layout, determine the brightness of the LED screen, and then do the computer lights, effect lights, the art of embellishment. In this way, the video technicians of each program can adjust the aperture on this basis to ensure that the visual effect and technical quality requirements of the screen.
Balance color temperature
Nowadays, it is popular to use a large number of computer lights to do surface light, that is, the use of high color temperature lamps and lanterns. Because the LED big screen for high color temperature equipment, if the computer lights use 2800 K ~ 3200 K or so of low color temperature lamps and lanterns, to the human face as the basis for exposure exposure, shot out of the Maipu color LED big screen will show blue, making the color distortion; such as the face of the light is adjusted to a high color temperature lamps and lanterns, and the back of the big screen in line up, so that the image presentation to form a consistent.
LED large screen to show the material can be moderately adjusted
Because of the use of large-scale LED screen, the resulting brightness will directly affect the stage lighting. We can first consider the LED screen as part of the stage lighting composition at the beginning of the lighting design. Measure the average brightness of all the playback material, edit and adjust the video screen brightness of the playback material and its color in advance, and according to the background material of the actual program, lighting design requirements, on the basis of not affecting the overall effect of the big screen, adjust its brightness appropriately, and the amount of light calculated into the basic illuminance of the light, the content of the big screen playback material as a part of lighting design to be integrated into the considerations, so that you can also Minimize the impact of the big screen on the lighting and camera aperture control.
