The use of stage lighting to light ratio is very rich, only to meet the audience's vision, very freedom. Many strong comedic effects are achieved by the contrast between bright and dark. TV lighting is not, and the maximum contrast allowed by cameras is limited. In TV lighting, the illumination can be compensated by adjusting the aperture of the camera to a certain extent, but the light ratio of the object being illuminated cannot be adjusted by the camera. If the light ratio of the object being illuminated is too large, beyond the allowable range of the camera, at this point, if the camera adjusts the aperture to the bright part of the object being illuminated as a standard, so that the details of the bright part can be reflected, then the dark part may be a paste. If the camera uses the dark part as the standard aperture adjustment, then the dark part will show hierarchy, but the light part may expose white. These are not ideal visual effects.
Designers for landscape lighting, often through the surface light, a slap in the face, side light, backlighting, background light, such as different lamp lighting, according to different requirements, the effect of different size of the illumination lamp configuration, light than required is different also, but in general, television lighting requirements than light cannot too big, if the cloth is too big, light reflected the camera images or bright surface exposure, Or the dark side becomes a black paste. Lamplight designer is in row, if discover TV picture to have this kind of circumstance in stage of dress rehearsal, want timely to be illuminated the light ratio undertakes adjustment.
The task of TV lighting is to control the illumination and light ratio of good scenery, and make scenery get good visual effect of TV picture through camera.
