industrial lighting

And this may be candles, household lamps, or special lighting devices that were previously explained in the first chapter. This is a big subject, and it needs books, even entire volumes. Therefore, we will briefly mention the rules of good lighting, with some mention.
Useful examples.
1- If the subject has only one shadow, because the eye is accustomed to seeing in the sun, which gives only one shadow to each object. As for the subject having more than one shadow, this gives an unnatural impression that detracts from the image. Unfortunately, this defect is noted in some TV programs

A, especially field news programmes. It is also observed in evening football matches where each player has four shades

-

- Equal to the main lighting, otherwise we lose anthropomorphism in the image. That all shadows be in one direction for one light source, even if we use dozens of lighting devices. But if the shadows appear in part to the right and another part to the left and then the right, then this indicates illumination that is not good at all

Good lighting rules:

The contrast in lighting between the areas of light and the areas of shadows must be within the capabilities of the film, in order for the details of the shadows to appear. Therefore, the areas of shadows must be opened with auxiliary lighting, provided that the lighting of the shadows is not

The lighting should be from a higher level than the subject, except in rare cases. As we mentioned before, such as the symbol of evil by illuminating the faces from below. Do not make light sources appear in the picture or show their reflection on any of the

Reflective surface shown in the photo. - The lighting temperature must be the same for the light sources. Part of the image does not appear with a yellow tinge and another part has a blue tinge. Only in special cases can the different even be overlooked

Street lights at night where sodium lights appear yellow and mercury lights blue | The green fluorescent lights and neon colors are different colors so like photographing
- Classic lighting: using continuous light sources (photofloods and spotlights). This lighting is mainly used for photographing people (portraits). It can be modified by changing places, distances, angles, and the degree of spread of the light of the electric lamps used to suit various other purposes:

Examples of lighting using artificial light:

This lighting is coordinated as follows:

I start first with the main lighting, and this is a medium-power spot or photo flood lamp. This is the most important lighting and is used to give the person shape, and to give a sense of depth and roundness through the shadows, which the photographer must control precisely. The most important shade is the shade of the nose, which should never be applied to the lip. This lighting determines the general atmosphere of the image, so the stronger the exposure and the greater the image, the brighter the image will be, light and smiling. The lamp shall be placed on one side of the camera at a distance of about a meter, not touching and rising from it at an angle of about 545
. After that we put lighting opening shadows. The purpose of this is to illuminate the areas of shadows created by the main lighting, in order to reduce the contrast of the image so that it does not exceed the possibility of the film, so that the details of the shadows appear. This lighting should not exceed its limit so that the main lighting prevails or the shadows are completely abolished. For this purpose, we use diffused light from a photoflood lamp with a large, wide reflector on which the light is distributed. This lamp is very close to and slightly above the camera

On the other side of the light bulb

Main. . Hair from C - Lighting the hair: After that, we put a spot to light the hair, and this purpose is to add a luminous touch of light and luster to the hair, and this lighting comes from a spot placed to the back and to one of the sides of the person to be photographed. To prevent light from entering the camera lens, a barrier is placed between the light and the camera outside the lens's field of view.

Background lighting: After that, we put a spot or photoflood to illuminate the background of the image. Its purpose is to make a separation between the person attached to the background, as well as to remove any shadows falling on the background. And this lighting is placed next to the person and directed to the background and the background so that it does not appear
