Design and application of TV lighting

Television lighting design is the combination of art and technology. Television lighting workers should use lighting to create art under various conditions, and restore or reconstruct the real and ideal space-time picture on the television screen. To clarify the overall working idea is the premise of TV lighting design.

How to use lamps and lanterns in TV lighting design

Familiarity with creative space and reasonable installation of lamps and lanterns

The organization and implementation of TV programs is carried out in a three-dimensional space. Lighting design should be carried out in a 360 degree area. Lighting designers should grasp the overall operation of the scene. The lighting design should create an ideal space for the director to create light, shadow and space, so that the actors can display their artistic talent and the cameraman can capture all kinds of scenery at will. In other words, to allow the camera to replace the viewer's eyes in the performance scene in an all-round "observation" of accurate and lifelike space-time environment, which requires lighting design to be familiar with and aware of the program implementation site structure and various types of program-related facilities such as lifting, rotating and translating to determine the layout of lamps, light and shadow tone and table. Now the rhythm.

Take the 800 studio studio of Shenzhen TV station as an example. The studio is 30m long, 20m wide and 20m high, 16.7M deep from the platform to the sky curtain, 10m deep and 14.6m wide in the performance area, 14.7m wide and 9.5m deep in the audience area, a total of 10 rows of 250 seats, the highest 3.1m, and the distance between the front row and the stage is 3.7m. There are five cameras in the studio: one on the left and one on both sides of the platform, one rocker on the right, one in the middle of the back row of the auditorium, and one swimming motor. The studio has more than 100 sets of lamps for different purposes. The general film and television lamps include: spotlight, return lamp, imaging lamp, sky curtain lamp, soft light reflective lamp, effect PAR lamp and tracing lamp, etc. Equipment such as smoke machine, snowflake machine and so on, and equipped with combined lamp holders.

1. application of spotlight

2kW video Spotlight: color temperature 3200K, effective projection distance 5m to 7m. Through the control system, lamps can act as level, pitch, cover, focusing and so on. Used as a spotlight for facial light, soft light (or in defocus) is often used to make light soft and uniform, and easy to overlap and connect when light is distributed on multiple layers; as a backlight spotlight, in order to meet the needs of a certain emotional atmosphere, color filters can be added to form an environmental tone.

2kW backlight: color temperature 3200 K, effective projection distance 8 m to 12 m. Usually backlighting. With soft film (paper), it can be used as an actor's face light. After assembling the color changing device, the cluster's strong backlighting effect and environmental hue are bright and bright.

3kW efficient tracking light: color temperature 5500K, effective projection distance 15m to 35m. In front of the stage, with Rayden 85 color warm paper, the color temperature of its light is reduced to 3200 K, so that it is consistent with the color temperature of the spotlight; in the rear of the stage, the color temperature of the spotlight is maintained at 5 500 K, they are used as the tracing surface light of the actor and the tracing back light, forming a special light effect. The column of the lamp can not only guide the audience's attention, but also give the stage more charm of movement.

Application of 2. floodlights

2kW Sky Lantern: the color temperature is 3200 K, effectively projecting distance 3m to 5M. According to the different requirements of different programs, different color filter paper is allocated to meet the needs of the background color of the program.

1.25kW * 2 soft light reflector lamp: color temperature 3200K, effective projection distance 5m to 7 m. This kind of lamps and lanterns play an extremely important role in the special environment which requires large area of audience, uniform distribution of light and emphasizes a certain degree of illumination. Its light is soft and delicate, without obvious projection, just forms a complementary relationship with the spotlight, which not only meets the illumination requirements of the surface color reduction, but also makes the shape of the group image appear more hierarchical.

3. application of effect lamps

PAR64 luminaire: color temperature 3200 K, effective projection distance 5m ~ 7m. Its lamps and lanterns play the role of "main force of effect". The light fixtures are all equipped with CP60 narrow beam bubbles, and some of them are equipped with color changing devices. The lamplight, combined with the on-site artificial smoke, can form a distinct spatial beam, forming a special spatial effect in the picture. At the same time, it can also form a dynamic atmosphere and artistic conception based on "space beam modeling" and integrate with the stage art atmosphere to complement each other in time and space.

Computer lamp: The computer lamp has the characteristics of high color temperature, strong beam, multi-directional projection, scanning, easy control and easy to change colors and patterns. Patterns and colors can be used independently and arbitrarily, and their high brightness and multi-beam effect are often used as space modeling to enhance the spatial, three-dimensional and perspective sense of the screen; the change and flow of the patterns enrich the content of the program; the powerful strobe function, as well as arbitrary dispersion, polymerization and flow. The overall effect of the cluster has created a brilliant artistic conception for the TV program, and also let the audience produce a kind of illusion that the stage is constantly jumping and running, so they can not help but participate in and participate in the program.

When recording TV programs with audience participation, special attention should also be paid to the fact that the audience is not only the viewer of the program, but also the "extras" of the program. They are not only the mood of the program, but also the foils of the scene. The location and lighting of the audience must be incorporated into the overall design of the TV lighting design.
