What are the applications of photography and lighting?

It is mainly divided into forward light, side light and backlight.

Shun light is the light from the back of the camera, because the light is evenly illuminated on the surface of the subject from the front direction, the light receiving area is large, the shadow is less, the metering and ** control is relatively easy when shooting, even if you use the auto ** mode, there will generally be no ** mistakes. But its disadvantages are also obvious - even if the surface of the subject is uneven, because the light intensity is exactly the same, the shadow is not easy to appear, which will cause the object to lack texture and three-dimensionality, and the whole ** looks flat. Frontal light is especially not suitable for larger scenes, such as landscapes, or portrait photos (you will usually find that in a group photo taken in the light, there are only two black holes left in everyone's nose.

Side light refers to the light shining from the side of the subject, which can make the surface of the subject show part of the shadow due to unevenness, so that the object is dismantled and concealed and the light and dark sides have obvious performance, which can not only outline the contour of the subject, but also reflect the three-dimensional sense, this kind of light is the most expressive, so the side light is the most commonly used light in photography. However, when using it, it is necessary to pay attention to the proportion of the light-receiving side and the dark side in the picture modeling. When the direction of the light is about 45 degrees from the plane of the scene, the angle of light makes the proportion of the light receiving side and the dark side of the subject roughly equal, which is more in line with people's daily life visual habits.

Backlighting refers to the light coming from behind the subject. It is easy to turn the subject into a silhouette when shooting with backlight, so it is relatively difficult to grasp the **, and backlight photography is often not recommended for beginners. But the artistic effect of backlighting is also unique – it imposes a striking contour on the outer edge of the subject (or gold in the case of sunlight).

If handled properly, you can create a unique aesthetic and shoot an artistic sense of light and shadow.

In order to reduce the light ratio, you must pay attention to the foreground light, you can use a reflector or a flash - if you see someone who uses a flash when shooting against the sun, you have to respect him, because he is an expert, he is shrinking the light ratio of the foreground to the background.

1. Three-point lighting: main light, background light, auxiliary light.

2. Subject light: directly in front of the object, mainly to illuminate the main object in the scene and its surrounding area.

3. Auxiliary light: increase the contrast between light and dark levels of the subject.

4. Background light: increase the brightness of the background, so as to set off the subject and separate the subject object from the background. Generally, floodlights are used, and the brightness should be dim but not too bright. Anyway, it's about layering the background and the object.

There are basically two main types of photographic lights: Flashing and Constant Lights.

The function of the flash: the general index is relatively sufficient, and the amount is sufficient. Each studio flash is composed of two parts: a flash cannon and a modeling gun, and the modeling lamp can see the final light effect in advance.

However, due to the power problem, the effect of the modeling light will be different from the effect of the flash flash at the end.

The role of continuous light: There are two categories of cold light still life light boxes and yellow and red head lamps in continuous light, and there are many specific subdivisions. The disadvantage is that the index is slightly lower than that of the flash, but you can intuitively see the final light effect, and what you see is what you get.

The types of photographic lights can be roughly divided into: three primary color cold lights, LED lamps, halogen lights, spotlights, flashes, stage lights, outdoor lights, news lights, and dysprosium lights.

Function: 1. Three-color cold light: color temperature is accurate, cold light source, mainly used in studios and conference rooms.

2. LED lamps: energy saving, long life.

3. Halogen lamp: traditional lamps and lanterns, thermal light source.

4. Spotlight: mainly used for stage and studio.

5. Flash: stage.

6. Stage lights: There are many types of lights, which can create a stage atmosphere.

7. Exterior shooting light: easy to carry, suitable for temporary shooting.

8. News lamp: a must-have for photography and videography enthusiasts and journalists, easy to carry, light in size and strong in practicability.

9. Dysprosium lamp: used in film and television production.

For advanced gamers, the camera light is an indispensable photographic device, and it is very useful in many occasions. In fact, photographic lights are a very important equipment in shooting, especially in outdoor scenes at night, such as barbecue and camping, photographic lights are indispensable and important equipment. With photographic lights, it is possible to expand the range of use of digital video cameras without being limited by light.
