What is the standard for setting the color temperature for photography?
The standard color temperature range was 5200°K - 5700°K, and the colors were natural. However, there would be different suitable color temperature settings for different shooting needs and scenes. For example, when shooting makeup, it is recommended to use a cold color temperature of less than 5200; the color temperature under direct sunlight at noon is about 5600K; the color temperature on cloudy days is 6200K; the color temperature at sunrise or sunset is about 2000K; the color temperature of candlelight is about 1000K; the light emitted by tungsten lamps is yellow due to the low color temperature; the flame of natural gas has a higher color temperature and is blue. If a Goldshell flash is used, the color temperature deviation can be controlled to be within 150K, which can be classified as a constant color temperature. In the camera, you can also adjust the color temperature of the photo through white balance to adapt to different shooting needs. Read more exciting novels for free
Standard photography
Standard photography required the following points: ** 1. Thematic ** 1. ** Clarity ** - There had to be a clear purpose for the shoot, such as taking a group photo of the meeting. The theme was to record the image of the participants and show the face of the team. - It could reflect a certain degree of interest or meaning, such as the characteristics of the event or the status of the participants in some standard photos of the event. 2. ** Avoiding meaningless content ** - You can't casually shoot elements that don't have any meaning to the theme. For example, in the standard photo of a formal meeting, you shouldn't include unrelated junk or unrelated people's movements in the background. ** 2. Main body related ** 1. ** Main body position ** - When composing a picture, you have to place the subject in the right position. For example, in a standard photo of a character, the face of the character (as the main body) should usually be in the center of the picture or near the three-point line. If it was a standard photo of many people, such as a group photo at a meeting, it was necessary to ensure that all the characters could be reasonably arranged in the picture and try to make the characters in the same focal plane. 2. ** Body Color ** - If the color of the main body was more conspicuous, it could better highlight the main body. For example, if the background color is relatively simple, the character wearing clothes with obvious color contrast (such as dark clothes on a white background) will make the main body stand out more. At the same time, if you want to highlight a certain person or group as the main body, you can also achieve it through color matching. For example, in a group of people wearing dark clothes, let the protagonist wear bright clothes. ** 3. Other aspects ** 1. ** Backstory processing ** - The background should be as simple as possible to avoid being messy. For standard photos, a solid background or a simple, meaningful background was a better choice. For example, the ID photo would use a pure color background. For the meeting photo, choose a simple conference room background wall or a landmark building (related to the theme of the meeting) background. 2. ** Aperture setting ** - If it was a standard shot with many people, the aperture should not be too large, because a large aperture would cause the depth of field to be too shallow, which might blur some of the people's faces. 3. ** Shooting Techniques ** - For standard photos with a large number of people (such as large conference photos), continuous shots could be used to ensure that everyone's expression was appropriate. Professional photoshop would be done later to improve the photo effect. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
ambient color temperature
The color temperature was a unit of measurement that represented the color composition of light. The unit was "K"(Kelvin). It was a physical quantity used to define the color of a light source in illumination. In theory, the blackbody temperature referred to the color of an absolute blackbody after it was heated from absolute zero (-273 ° C). After the blackbody was heated, the color gradually changed from black to red, yellow, white, and finally blue light. When heated to a certain temperature, the spectral composition of the light emitted by the blackbody was called the color temperature at this temperature. If the light emitted by a light source has the same spectral composition as the light emitted by a black body at a certain temperature, it is called a certain K color temperature. However, it was difficult to determine the specific value without more background information because different environments had different color temperatures. For example, the color temperature of indoor lighting may be between 2700 - 4000K (warm light to neutral light range), and different lamps, natural light sources (such as sunny and cloudy), etc. will affect the color temperature of the environment. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Color temperature for design
In lighting design, the choice of color temperature depends on the specific needs of the place. The following are the color temperature design suggestions for different locations: - ** Home environment **: - The overall color temperature of the home decoration was recommended to be 3500K-4000K. Among them, the 3500K color temperature was warm, giving people a warm, lazy, and relaxed feeling, while the warm white light around 4000K made people happy and comfortable. However, when the use of different spaces in the home is changeable, such as the living room and bedroom, it is best to choose an LED lamp with a color temperature that can be adjusted. For example, the bedroom is suitable for 3000 - 3500K color temperature lighting before going to bed, which is good for sleep, and high color temperature lighting is good for thinking things; if the bedroom uses a color temperature lamp above 5000K, excessive blue light will suppress the brain's meltdown release, affecting sleep and sleep quality. According to the National Building Lighting Design Standard, the color temperature of guest rooms and bedrooms should be less than 3300K; the kitchen is not recommended to use warm light. A color temperature of 3500 - 4000K with a color rendering index of more than 90 is better, which can make the taste sensitive and the space clean and tidy. Two color temperatures can be prepared for the bathroom, and the comfortable color temperature should be selected according to the season. - ** Office **: Generally choose 4000 - 5000K, close to natural light, making people feel bright and focused, so that they can quickly enter the working state to improve efficiency. - ** Shops, hospitals and other places **: suitable for cold light (above 5000K), can enhance the brightness of the space. - ** Lobby, restaurant, bathroom, etc. ** Neutral light (3300K-5000K) can create a natural feeling in the space. - ** Living room, bedroom, exhibition area, etc. **: Warm light (below 3300K) can be used to decorate the atmosphere. At the same time, when choosing the color temperature, psychological and aesthetic issues should also be considered. It depends more on factors such as illumination, the color of the interior surfaces and furniture, the climate environment, and the application site conditions. Usually, warm color temperature should be used in low-illumination places, intermediate color temperature should be used in medium-illumination places, and cold color temperature should be used in high-illumination places. In warm climate conditions, cold color temperature may be more inclined, and in cold conditions, warm color temperature may be more inclined. Under normal circumstances, intermediate color temperature should be used. It was also best to use lamps of the same brand and batch in the same space to reduce the influence of color temperature difference and color tolerance. If there was no brilliant design technique, try not to use two color temperatures in the same space. If used, the difference should not exceed 500K. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The color temperature of spring
There was no specific value for the color temperature in spring. It was only known that spring used a kind of contrast color temperature, and spring liked green lighting.

The color temperature of the makeup lamp
The color temperature of the makeup lamp was generally 5000K-6500K. This color temperature range could provide sufficient brightness and accurate color reproduction, which would help make makeup more precise and accurate. At the same time, the light under this color temperature would not be too dazzling or dim, which could protect the eyes and provide a better observation effect. If you want a more professional makeup effect, you can add a soft light source around the mirror, such as LED light strips or soft light boards, to make the lighting more uniform and soft. You can also adjust the brightness and angle of the light to suit different scenes and makeup needs. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The standard of table setting
The table setting standard included the following requirements: First, the tablecloth should be laid neatly, the raised seams should overlap with the middle seams of the table, and the middle raised seams should be upward. Secondly, the order of placing the vase, salt and pepper bottle, and candlestick should be placed according to the distance from the center of the tablecloth. The vase should be placed in the middle of the table, the salt and pepper bottle should be 10CM away from the vase, the salt bottle should be on the left, and the pepper bottle should be on the right. The candlestick was 10CM away from the salt and pepper jar. The display plate, bread plate, and mouth cloth were also placed in the middle of each table. The distance between the plate and the table was 2CM. The bread plate was on the left side of the display plate, 5CM away from the display plate and 2CM away from the table. The cloth was placed on the display plate, facing away from the guests at an angle of 45 degrees to the right. In addition, the main knife and fork, butter knife, and red and white wine glasses needed to be placed. When setting up the stage, there were also requirements for the appearance of the staff, including keeping their hair clean, nails clean, and dressing neatly.
Using practice to measure the temperature of photography
Based on context alone In the field of photography," measuring the temperature of photography with practice " had rich implications. In terms of technical practice, photographers needed to constantly pick up the camera to practice shooting. For example, shooting under different lighting conditions, such as soft sunlight in the morning, strong direct light at noon, or artificial light at night, by adjusting the aperture, shutter speed, sensitivity, and other parameters, you can feel the impact of these elements on the final effect of the picture. During the shooting process, one would gradually understand what kind of parameters could capture the most touching moment, just like accurately capturing the warm color of a bonfire in a cold environment, or the comfortable expression of people enjoying the cool on a hot summer street. This was the visual "temperature" in the perception of the image. From the perspective of creative practice, shooting in different scenes and crowds was also a way to measure the temperature of photography. They walked into the ancient village and filmed the persistence and inheritance of traditional craftsmen. Their focused expressions, rough hands, and ancient tools conveyed a kind of persistence and love for traditional culture under the camera. This temperature was a respect for cultural inheritance. Or walk into the corners of the city and record the figures of ordinary workers. Whether it was the cleaners cleaning the streets in the morning or the delivery men who were busy late at night, the images captured by the camera reflected the true temperature of life. From the perspective of emotional experience, the photographer used his own emotional input to find those warm images. For example, the interaction between relatives during family gatherings, the joy of the family when a newborn was born, the grief of relatives when an old man passed away, and so on. Every time the shutter was pressed, it was a measure of the temperature of these emotions. The invisible emotions were solidified by photography, allowing the audience to feel the love, joy, sadness, or hope through the photo. In short," measuring the temperature of photography with practice " was to explore the depth and breadth of photography through continuous shooting practice, from technology, creative content to emotional expression, so that photography works were full of appeal and vitality. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Color temperature preference in America and Europe
European people's eyes were blue and more sensitive to light. They preferred low color temperature screens. For example, in terms of lighting, European light culture preferred low color temperature and high display. Low color temperature light made white skin not pale, and warm colors could create different ambiances and control the saturation of the picture. In North America and Europe, blue represented trust, security, and authority. It was considered a color that comforted and calmed people. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Dual color temperature power supply
The dual color temperature power supply was a power supply that could achieve two color temperature adjustments. For example, Zhejiang Arc Light Intelligent obtained the patent for the multi-color temperature controllable LED driver. Its light source module includes a cool light emitting unit and a warm light emitting unit. The color temperature can be adjusted through the color temperature control module. There were also a variety of dual-color temperature power-related products on the market, such as the Aqara dual-color temperature driver T1 Pro, which could be used as the power supply and driver of the spotlight, and the Lanchey dual-color temperature smart light strip with a power supply of 300W. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
