Standard for Office Lighting
There are many standards to consider for the layout of office lamps: 1. ** Illumination standard **: - The standard value of illumination for the working surface of an ordinary office is 300lx according to the standard value of GB50034 - 2013. - The illumination of the background area of the work surface should generally not be lower than 1/3 of the illumination of the adjacent area of the work surface. - The illumination degree must be no less than 0.6 (the ratio of the minimum illumination on the specified surface to the average illumination). 2. ** Glare Control **: - To avoid glare, glare can be produced by direct glare (light that enters the eyes in normal vision) and reflected glare (such as reflecting light from a lamp through a computer screen, causing glare or affecting the observation of screen text). - Diffuse lamps and other methods can be used to reduce the impact of glare. 3. ** Lamp position **: - The general lighting should be on both sides of the work area, and it is not advisable to arrange the lights in front of the work position. When it is difficult to determine the work position, choose a lamp with a large luminous area. 4. ** Illumination Method **: - All the lights were down (such as embedded and ceiling), and the lighting was even but the ceiling was darker; the semi-indirect lighting had light up and down, which was more comfortable and energy-saving; the light of the lamp was completely up, and the space was illuminated by the reflection of the ceiling. The view was more comfortable but it might waste energy. 5. ** Combination with the environment **: - The reasonable lighting arrangement should match the office decoration style of different spaces, beautify the office environment, and combine with natural lighting to form a comfortable lighting environment. 6. ** Energy Saving Requirement **: - When an ordinary office reached 300lx, only 9W/m2 of electricity was allowed; when a high-end office reached 500lx, only 15W/m2 of electricity was allowed. By controlling the lights reasonably, such as giving a separate switch to the lights by the window so that they could be turned off during the day when the light was good, it could save energy.

Lighting Ceremony
The ignition ceremony was a ceremony to celebrate the official start of a new project or factory. The ignition ceremony usually included the following contents: the host announced the start of the ceremony, the leader of the organizer gave a speech and introduced the situation of the factory, the leader or representative of the higher authorities gave a speech, the employee representative gave a speech or took an oath, the top leader announced the official start of the ceremony and carried out the ignition or launching ceremony, and set off firecrackers to celebrate. The host announced the end of the ceremony and led the guests to visit the production workshop. The ignition ceremony also involved other preparations, such as inviting leaders, VIPs and guests, specially invited reporters from news agencies, custom-made gifts and souvenirs, inviting well-known hosts, coordinating the venue, and arranging security staff. The specific ceremony process and event planning may vary according to different companies or projects.
Lighting Colors
In terms of natural light, the color of sunlight would change many times a day. It would be blue in the morning, orange at sunrise and then scorching red. It would be close to blue-white at noon, and it would transition from dark red to orange to dark yellow at sunset. It would turn dark blue when the sun was about to set. The night sky was different depending on the phase of the moon. Sometimes, there was pale moonlight, and sometimes, it was dark (rarely seen in the city, artificial light would illuminate the night sky). In terms of artificial light sources, incandescent lamps emitted red light, energy-saving lamps emitted white light, and some artificial lights emitted light yellow or reddish light. Neon lamps mostly emitted green light, sometimes blue or yellow. Light-emitting LED lamps and halo lamps emitted blue light, and floodlights for construction were dark red. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Lighting Color
The color of the photography light involved the knowledge of color temperature. Different color temperatures would present different color effects. Generally speaking, 5600K was closer to the color of sunlight, which was pure white. The color temperature of blue was high, while yellow was low. Different brands and models of photography lights may have different color temperatures. For example, some photography lights may be cold (blue), some may be warm (yellow), and some may be green. When using multiple photography lights, you may find that there are differences in color, which requires consideration of white balance to adjust to achieve the desired shooting effect. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Lighting in the studio
There were many ways to light an indoor camera: - Single-light portrait shooting: Many photographers advocate single-light portrait shooting as if it was a sun. The light can be adjusted according to the subtle changes in the natural weather. Pay attention to the light, otherwise you can use the umbrella tool. Under strong light, the skin texture should be as good as possible. The position of the light should be on the person's head as much as possible. You can choose a soft umbrella to create a uniform light. - ** Multi-Light Portrait Shooting **: - In principle, there was only one main light source for multi-light shooting, and the other lights played a supporting role. For example, when two lights were used, one was the main light and the other was the supplementary light or auxiliary light; when three lights were used, one was the main light and the other two were the supplementary light or auxiliary light. - There were three points to note: First, soft light cover and reflective umbrella could be used according to the needs to soften the light; Second, due to the characteristics of the digital sensor, it may weaken the three-dimensional effect of the picture. In actual shooting, try to use a silhouette light to enhance the three-dimensional effect; Third, the actual shooting should be based on the distance and the characteristics of the light. - ** Double Lights Portrait Light **: A different way of light distribution from the traditional double lights is that the main light with a reflective umbrella is located at the upper left with 1/2 light output, and the auxiliary light with a soft light box is set on the right with full light output. The auxiliary light can emphasize the outline and the three-dimensional effect of the model, and the soft light can illuminate the rich details of the model. The exposure is based on the output light of the main light. This kind of light distribution was suitable for digital photography. It could make the main body of the model clear and three-dimensional. - ** Multi-light portrait lighting example (three lights)**: The traditional method is that the main light is softer on the upper left, there is an auxiliary light with a soft light box on the upper right, and there is a background light behind (suitable for a single-color background to make the background beautiful). The auxiliary light can enrich the details. This method of light distribution did not require high accuracy and was suitable for beginners. When shooting with many people or when the movement changes greatly, the main focus is on the direction and illumination area of the main light. Moving the main light can take photos with uniform light ratio. For example, two 1600W lights and a soft box were completely backlit. The front of the model was facing the direction of the mirror to illuminate the front and face. The backlit light outlined the outline of the model. The use of the mirror could make the model's face layered. When shooting, pay attention to the side light of the face and adjust it downward to prevent the outline light from disappearing and overexposing. - ** Common Light Type and Function **: - ** Main light **: It is the preferred light that determines the lighting pattern of the subject. It is usually emitted by the soft light box. The illumination distance and angle can be adjusted according to the needs. The exposure of the photographic image is determined by the main light. The main light could modify the face of the character, make up for the uneven skin color and the shortcomings of the face shape on the camera, and portray the appearance of the character to show the inner activities. - ** Fill-up Light **: It is used to supplement the lighting of the shadow part of the picture, making the shadow lighter. It is also emitted by the softbox. The photographer adjusted the power of the soft light box to control the depth of the shadow, so that the fill light and the main light formed the best light ratio. The soft box for fill light can be placed near the camera, on the other side of the main light, and at the same height as the lens to produce a uniform fill light effect. - ** Backlight **: Using the background as the light source. In most cases, there is a distance between the subject and the background. The function is to separate the subject from the background. The lamp should be behind the main body and higher than the main body. When using it, the color, distance, and lighting angle of the background should be fully considered and adjusted repeatedly. In addition, some special equipment could also be used for lighting. For example, when using a small portable projector as a light source, pay attention to its placement angle and strength. The projector is a hard light source. If you don't want the light to be too hard, you can use a soft light board in front of the projector, but it may sacrifice the clarity of the projected image. You can also use Christmas lights to hang it on the wall, so that the main character of the photo is in a position some distance away from the front. You can make shallow depth of field and beautiful bokeh effects by adjusting the aperture (f/1.4 - 3.5), using telephoto (50mm +), or close to the main character. There were also lighting techniques such as installing a 150B imaging lens and inserting an insert to emit window light, then adding a 500B ceiling light to make the light and shadow transition more natural, or using a 350W calfskin as a surface light, installing a spotlight in front of the lamp to emit window light, and then using foam boards to fill in the dark details. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Lighting effect map
The design of lighting effects involved many aspects. First of all, he had to consider the aesthetic relationship between light and space. He had to understand the direction, intensity, and color of the light, and use these factors to create a rich and three-dimensional effect. At the same time, he had to pay attention to the softness and comfort of the light to avoid excessive lighting that would cause dazzling and discomfort. Secondly, to achieve the perfect combination of technology and art, to understand the characteristics and application range of LED lights, neon lights, floodlights, and other lamps, and to create a unique visual effect through innovative lamp arrangement, light control, and color matching. In addition, it was necessary to show culture and characteristics, excavate the unique cultural and historical background of the city and integrate it into the lighting design, such as using light projection to tell the historical story of the city or display characteristic buildings and cultural symbols. In addition, ecological and sustainable considerations should be carried out, energy conservation and environmental protection should be emphasized, low-energy and long-life lamps should be selected, lighting layout should be rationally planned to avoid adverse effects on animals and plants, and regenerative energy and intelligent control technology should be actively adopted. He could also analyze the successful cases of different scenes such as commercial districts, parks, and bridges to better combine the design concept with the actual needs, thus creating amazing lighting effects.
Lighting for macro photography
Lighting for macro photography refers to the technology and equipment used to illuminate small objects at close range. The goal was to create a perfect balance between shadows and highlights to highlight the beauty of the subject and reveal its subtle differences, allowing the photographer to evoke emotions and tell stories in the image by controlling the interaction between light and the subject. In macro photography, proper lighting was very important. Light affected all aspects of photography, such as color, contrast, focus, and depth of the image. The subjects of macro photography were often small and fragile. Some subjects were easy to disappear in the shadows or overexposed under strong light. Precise control of light could convey the beauty, texture, and details of the subject, giving the audience an intimate experience of the subject. The key concepts of macro photography lighting are as follows: 1. ** Strength **: It measures the intensity of the light shining on the subject. By adjusting the intensity, you can create a dynamic range of brightness and contrast in the macro photo, shaping the visual effect. 2. ** Direction **: The direction of the light is like the angle at which the performer on the stage projects the light. It determines the position of the shadows and highlights on the subject. Different angles will greatly change the mood and visual texture of the photo. 3. ** Diffuse **: Can be regarded as a natural light softening filter. Using a diffusing device or regulator to disperse light could reduce the glare of shadows and produce soft and uniform illumination on the entire subject. It was an important means to achieve a delicate balance between light and shadow. 4. ** Color temperature **: It is measured in Kelvin. It is similar to the filter in the photo application. It can determine whether the macro lens is warm (gold) or cold (blue). Mastering the color temperature helps to convey emotions and atmosphere through the interaction of light. 5. ** contrast **: refers to the contrast between the brightest and darkest areas in the image. The use of contrast can enhance the dramatic effect, emphasize the texture, and draw the audience's attention to specific details, thus creating a visual narrative. The lighting equipment used in macro photography included flashes. The flash at the top of the camera is more convenient, but pay attention to its strong shadows. You can use a diffusing device to soften its effect to achieve balanced lighting. In the actual shooting, different lighting conditions had different shooting techniques. For example, it was more suitable to shoot macro shots on cloudy days. The light was uniform, the light ratio was balanced, and the composition was good. On sunny days, due to the influence of clouds, trees, buildings, etc., there would be high and dark light areas. The subject should be selected to be shot with more uniform light. If it was all in the sun, the picture could be taken with less exposure to preserve the details, and the brightness could be repaired later. The lighting in the room was more complicated, and the principle of choosing a scene with uniform lighting was also followed. There were also some special lighting techniques, such as using fairy tale lights (miniature LED lights) for creative macro photography. Fairy lights came in many colors, and different colors would bring different tones to the photo. Because the fairy tale lights were not very bright compared to the ambient light, it was necessary to shoot later in the day. If the subject had shadows or it was cloudy, the shooting could start a few minutes before sunset. When using fairy lights, the lens aperture is usually selected to be as large as possible (such as f/2.8). After measuring the subject, the image can be deliberately underexposed. You can also use a macro lens or a fast lens such as 50mm f/1.8. When using the fairy tale lamp, the lamp can be placed directly behind or in front of the main body. When placed at the back, the shooting distance will be shortened if it is under high magnification or large aperture. The distance should be increased if it is further away from the subject or when using a narrow aperture. When placed in front, it should be close enough to the lens to maintain out-of-focus. In the case of insufficient light, using a flash is a better choice. When there is sufficient light, you can achieve pure natural light shooting, but sometimes in order to achieve certain shooting effects, you can use light even if there is sufficient light, such as to highlight the subject, simplify the messy background, or to make the subject appear special (such as when shooting a young ladybug that has just shed its skin). On the other hand, if there is enough light in the environment, do not use the light when it should not be used. You can judge whether the light is used from the perspective of the subject's eyes and legs. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Model photography lighting
The following are some common lighting methods for model photography: 1. Butterfly Light (Paramount Light): - [Effect: It can achieve the effect of slimming the face. There will be a butterfly-shaped symmetrical shadow under the nose, which is a relatively beautiful and likable light.] - Light position setting: Place the light source above the model and point it at the model's cheeks, creating a dramatic shadow under the nose and chin. 2. Ring Light: - [Effect: The light effect created can be flat or narrow.] - Light position arrangement: Starting from the position of the butterfly light, the position of the light should be high enough to cast a perfect arc shadow under the cheekbone. Then, the light source should be moved slightly to the right or left to change the position of the light source until the shadow appears on the other side of the nose, forming a ring. 3. ** Rembrandt Light (Triangular Light)**: - [Effect: The transition is natural and smooth. The most important feature is the "triangle on the cheek." The picture looks both dramatic and natural.] - Light position arrangement: push the light slightly forward to the right or left of the ring light setting, and point the light at a steeper angle. When shooting, the shadow side of the subject's face is facing the camera. Use a light source and a reflective light source, or two separate light sources, to form a triangular light spot on the front part of the face (the projection of the brow bone and nose bridge, and the dark area of the cheekbone). 4. Split Light (Side Light): - [Effect: Easy to achieve indoors. It is suitable for creating a mysterious atmosphere. The scene will show a strong drama, showing the character's personality and temperament.] - Light position arrangement: The main light only illuminated half of the subject's face (the side of the subject, left in the shadows). 5. ** Edge Light **: - Effect: It is very suitable for separating the subject from the background and accentuating the outline. - Light position: Place a light source behind the subject and tilt it toward the back of the head. This auxiliary light source should be stronger than the main light source from the front to get more drama. 6. ** Revealing Light **: - [Effect: Prominent model's wide face.] - Light positioning: Turn the side that receives the light to the camera, or place the light source on the right or left side of the subject and tilt it towards her, and let the model move away from the light source and face the camera. 7. ** Skinny Light **: - [Effect: Makes the face look sharp and has a more three-dimensional feel.] - Light position arrangement: It was the opposite of the wide-light. After the wide-light photo was completed, the light source could be moved to the other side of the model. The model could also turn her body to the side of the light source and push the wide side of the face into the shadow. 8. ** Silhouette Light **: - [Effect: It is suitable for models who ignore the appearance of the model and pursue the outline of the body. It is suitable for models with three-dimensional facial features.] - Shooting method: Let the light part be exposed normally, and the natural dark part be exposed to black. 9. Backlight: - [Effect: It can create a hazy feeling. It is more effective for women.] - [Shooting requirements: It needs to be used with a reflective board, otherwise it will look like a silhouette shot.] 10. Narrow Light: - [Effect: The light can only be displayed at the edge of the model's face. When used with a reflective board, it can reflect a sense of mystery and concentration.] - Light position arrangement: The light position is behind the model. 11. [Contour Light]: - [Effect: Create a solemn and mysterious feeling, highlight the model's focused eyes, suitable for models with three-dimensional facial features.] - Light position arrangement: You can use it as a character's decorative light and place it behind the subject to make the hair have a high level of light, so that the face has a very good outline. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
