Common sense of fill light station

1. What lighting is used for photography?

Photographic light, there are roughly the following situations; 1 When the light is insufficient, use the flash as the auxiliary light source. 2. Take photos at night and use the flash as the main light source. 3. Shoot an object or portrait in the backlight, and fill the dark part with a flash. 5. In order to make up for the lack of light with the given aperture and speed, trick photography used a flash to make up the light. In artistic photography, natural light is generally not used as a light source, and many flashlights are often used to adjust the light consumption of the subject. There are: main light source \ auxiliary light source \ background light source \ ceiling light source and eye light. In the process of use, flexible use and reasonable arrangement. When using a film camera, choose a reasonable light source such as sunlight film according to the film type, and shoot under the condition of sufficient light. Although there is sufficient light, the color temperature of the photo can be changed by using a flash at this time to prevent the color difference of the photo.

2. Explain in detail how to use the common sense of headlights that should not be missed.

There are many kinds of car lights, such as turn signals, brake lights, far and near lights, fog lights, emergency lights and so on. How to use these lights correctly in different occasions is often very confusing for novices. Driving school coaches usually only teach turn signals, but the knowledge of car lights is very profound.

Many driving school coaches will only briefly explain the turn signal when teaching, and wait until the students officially go on the road after research, but they regard it as "car blindness." How to use car lights correctly is of great significance. Today we will interpret the usage of various car lights.

turn signal

The vehicle must be turned on when turning, and it will automatically blink intermittently to remind the vehicles and pedestrians around. The turn-on time of the turn signal should be well controlled, and it should be turned on when it is 30 meters away from the turning intersection to 100 meters. If you drive too early, you will have the illusion of "forgetting to turn off the turn signal" for the following car. If you drive too late, the cars and pedestrians behind you will be caught off guard and often make mistakes in your busy work.

Night width indicator

Commonly known as "small light", it is used to display the width and length of the car body at night, and should be checked frequently during maintenance. Some friends think that small lights can't play a role in lighting and don't pay enough attention to them. This is very wrong.

night illumination

Headlights, commonly known as "headlights", are the "heart" part of all headlights. "Headlights" should be checked frequently. You can go to a professional repair shop to adjust the lighting height and angle to meet the driver's best sight. When using headlights, you should use low beam when overtaking, and change the high beam according to the situation after overtaking to maintain farsightedness. When overtaking at an intersection, change the far and near lights to remind passing vehicles.

Brake light

Strong brightness, used to inform the rear car to slow down or stop, and often check the brake lights. If the brake light is damaged and not replaced in time, it is easy to cause rear-end collision, which is harmful to human cervical spine.

fog light

Fog lights should also be checked frequently to prevent sudden fog, rain and snow weather, or to warn the car to pay attention in an emergency and take timely measures. Therefore, drivers must turn on fog lights when driving in foggy days, and can't use small lights instead. Fog lights are also unsafe after non-foggy days, which affects the driver's sight.

Emergency signal lamp

Many car owners haven't used the emergency signal light (double flashing) for a long time, and don't even know where the switch is and how to use it. Some novices are nervous when driving on the road, but don't use the emergency light for a long time when there is no emergency, or pay attention to the sound inside the car to prompt them to turn it off in time (double flashing), and often check whether the emergency light is normal.
