Operation of stage lighting

2021-06-25

In stage performance, how the lighting operation will directly affect the stage lighting effect, and even affect the effect of the whole stage, so the lighting operator should not only have the basic knowledge of lighting, but also be a skilled lighting technician, not only have experience, but also be familiar with the stage art creation. Lighting operators have their own division of labor, some operate in front of the screen, some operate behind the scenes, and some operate on the console. Although the division of labor is different, they all need to work together according to the designer's intention and concentrate on their respective positions.

 


1、 Preparation before operation

1. Before the performance, the lighting operators should first read the script, and have a deep understanding of the scene, characters, plot and action, so as to better understand the intention of lighting design.

2. Secondly, you should participate in the rehearsal of each play, even if the time is tight. During the rehearsal, you should pay attention to the movements and expressions of the actors, listen to the lines and music in the program, and remember every detail in the rehearsal process.

3. Read the lighting design book carefully and discuss with the designer to make the implementation and operation of the design book concrete. During the stage arrangement, there may be some changes in the design book, and the changes shall be recorded in time.

4. Install according to the lighting installation list in the design book. The installation is usually carried out the day before the rehearsal, and the operator can consider adopting a more convenient method for installation.

 


2、 Practical operation

1. Operation of footlights: the height of footlights is generally fixed, but the height of some song and dance programs needs to be adjusted properly. If footlights are not used, they can be stored.

2. The operation of top light arrangement - adjust the height of the top light according to various stage devices and different scenes. Recently, electric adjustment has been adopted and can be stored by computer. Every scene can be adjusted accurately.

3. Operation of band lamp no matter where the band lamp is hung, the angle and height of the hanging should be paid attention to first. For example, when it is hung on the top lattice window, it has different effects to tilt 45 degrees or 90 degrees to the lower part. Whether it is facing the interior or exterior scenes of the house, it should have a tilt angle. The height of the suspension and the distance from the background or the sky curtain should be in accordance with the position specified by the designer. This position has been determined by stage rehearsal, and the change of distance will affect the brightness, so the operator should pay attention to the installation and consider the effect during operation.

4. Operation of spotlight - the following points should be noted in operation of Spotlight:

The light source of a spotlight is usually set on the optical axis of the lens (i.e. the central line).
Put the light source on the focus of the spherical mirror.
Make the plane of the filament of the bulb parallel to the lens.
Always keep the lamp can be up and down, left and right free operation, and can cooperate with its device smooth operation.
When following the action of the character (light tracing), the center of the light column should be near the chest of the character. In case of special circumstances, the operation should be carried out according to the requirements of the designer.
In order to project light accurately, it is necessary to determine the target of the illuminated surface in advance.

5. Operation of arc spotlight and xenon spotlight

After the arc is fully stable, open the aperture to cast light.
Close the aperture when lighting.
The contact surface of the electrode or positioning screw in the lamp should be large, tight and firm.

6. Operation of the projector the operation of the projector is relatively complex, and the operator should have a high level in both theory and practice. In addition to relying on experience and proficiency, we should also pay attention to the following items:

As with the operation of spotlight, attention should be paid to the use of light source and lens. There are two methods for projecting to the screen: objective lens moving method and base plate moving method.
In addition to short-range, most use arc lamp or xenon lamp as light source. If the bottom plate is similar to the glass of the photographic board, special attention should be paid to the temperature and protective measures should be taken to avoid damaging the bottom plate due to the high temperature in the projection process.

 


7. Operation of light control panel and console

The lighting control panel and lighting console are the heart of the stage. The lighting effect of the whole performance depends on the operation on the console. The operation of the console is best controlled or operated by the lighting designer, or by the lighting team leader. The following items should be paid attention to during the operation:
Be familiar with the structure, function and operation method of the control panel.
In the process of operation, he was calm, alert and accurate, and operated according to the changes of lighting design and performance.
Even if the lighting equipment is all modernized, accidents will inevitably occur. When there is an accident, we should be calm and solve it according to the alternative plan, so that the performance will not be affected.
In the operation, with the drama or dance of all kinds of tips, lights constantly change. Therefore, in the process of performance, whether it is the scene change, the actor's action or voice tips, we should skillfully and predictably grasp these tips.
With the continuous development of stage culture and art, the content and form of performance are increasingly various. With the progress of science, the lighting equipment is constantly updated. Therefore, the stage lighting workers should continue to learn and master the advanced lighting operation technology to serve the stage performance.
