Tianjin Tilted Photographic Model Compressed
There were usually the following methods to compress an oblique photography model: 1. ** Noodles decreased **: - The QEM algorithm could be used to reduce the number of triangular patches by optimization of the position and normal of the triangular patches, thereby reducing the model. Although the simplified model might lose some details, the rendering speed would be faster. 2. ** LOD-simplified **: - Using different levels of detail (LOD) to simplify the model. High-level details (including all aspects) are magnified by the user or presented from a specific angle, while low-level details are used from a distance or from a different angle. Different levels of grids can be created and stored in OSGB format files. The OSGB format also supports zLib or LZMA-based compression, which can reduce the file size for faster transmission and loading. 3. ** Use specific software to operate **: - For example, he could use the oblique photography processing software, Ling Yi Zhi Mo, to open the oblique photography model file in the OSGB format, right click on the parent node in the Layer window, and select [export]. - If you want to export to OSGB format: select [OSGB] and click on the advanced option. Set [Maximum Level] and [Image Quality] according to your requirements, and then click [Confirm] to complete the compression. - If you want to export to 3DTiiles format: select [3Dtiles] and click on the advanced option. Set [Maximum Level],[Image Quality],[Draco Compressed] according to your requirements, and then click [Confirm] to complete the compression. 4. ** Using 3D Factory Software **: - This was a professional software for lightweight processing of 3D models in the OSGB format. The lightweight compression ratio was high, the model lightweight efficiency was high, and the automatic processing ability was high. Under the premise of ensuring the model quality, it could greatly reduce the size of the model file. The processing speed was fast, and it could also support the lightweight compression of super large models. 5. ** Point cloud compression processing (lightened point cloud data for 3D models in oblique photography)**: - Strengths: - Reduce data volume: It can reduce the amount of point cloud data to a fraction or less, reducing storage space and transmission bandwith requirements. - Speed up data transmission and processing: Reduce data transmission time and cost, speed up data processing and analysis, and improve work efficiency. - Maintaining data accuracy and quality: Modern compression algorithms can reduce the amount of data while maintaining data accuracy and reliability. - Usage: - Data transmission and storage: Reduce transmission time and cost, and reduce storage space requirements. - 3D Model Visualization: Realizing faster and smoother 3D model display and interaction, improving user experience. - Terrain analysis and application: In the fields of urban planning, land use, resource management, etc., it can be used to generate high-precision terrain models and perform terrain analysis and decision support. - Challenge: - The compression algorithm is complicated: the point cloud data has many scattered points and a complex structure, so it is difficult to develop an effective compression algorithm. - Data maneuverability: Over-compression will result in loss of data accuracy and quality, affecting subsequent analysis and application. - hardware and software limitations: Requires a large amount of computing resources, increasing system cost and complexity.

The Experience of a Photographic Model
Here are some tips that a photography model might have: 1. ** In terms of expression management ** - The model had to develop the habit of "smiling at the camera." When you're not taking photos, you can practice the expression of smiling in front of the mirror and find a way to make yourself look good. This was because in portrait photography,"smile" had a high click rate when taken from the front or side of the face. This could reduce the chances of the photographer capturing a strange expression. - When not smiling, you should express your emotions according to the filming environment. - The model couldn't see the effect of the photo and might subconsciously frown or have other ugly expressions, so the photographer could give guidance during the shoot, such as reminding the model to smile or adjust her expression. 2. ** Postures and postures ** - Pay attention to the expression of body language, such as the placement of hands, the posture of legs, etc. For example, the hand could lean against the mouth to take a close-up shot, and the leg could bend to create a layered feeling. He could also use some actions to increase the storytelling of the scene, such as brushing his hair and touching the surrounding objects (such as grass in the grass). - In different scenes, you have to adjust your posture according to the theme and style of the shoot. For example, in a retro style scene, the posture and overall bearing had to match the corresponding atmosphere. 3. ** Cooperation with photographers ** - The model needed to communicate well with the photographer and understand the photographer's intentions in order to better present the results. - Because the model couldn't see the effect of the shot, she often needed to rely on the photographer's guidance, such as adjusting her expression, posture, and position in the scene. 4. ** Personal image and aesthetics ** - Pay attention to your own image, including clothing, hairstyle, etc., to match the shooting scene. For example, in an environment with the style of the Han and Tang Dynasties, it would be more appropriate to wear clothes with the style of the Han and Tang Dynasties. - He had to have a clear understanding of his own strengths and weaknesses. He had to try his best to show his strengths and avoid exposing his weaknesses. For example, some models might not look good from certain angles or movements, so they needed to be avoided or improved. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

photographic sharpness
Acuteness was a physical measurement used to measure the quality of the edge of a picture. The quality of the edge was related to the definition perceived by the human eye. It could also be simply understood as the clarity of the picture. The sharpness of the image could be judged from the clarity of the edges and details of the object in the image. The higher the sharpness, the clearer the details of the image. On the contrary, the image was blurry and the details were not well expressed, and the edges were not coordinated with the entire image. In photography, sharpness had the following characteristics and effects: 1. ** Relationship with contrast **: The higher the sharpness, the higher the contrast of the edge; increasing the contrast of the edge, the sharpness will also increase. 2. ** Effects on different subjects ** - [Portrait photography: Sharpness is not always better.] If the sharpness was too high, the character's skin would have a grainy feel, like a full face full of potholes. It might also cause the edges of the face, hairline, eyebrows, eye sockets, nose, lips, and other black and shadow parts to have white edges, affecting the image. - ** Landscape photography **: Most of the time, they pursue sharpness. High sharpness can make the picture instantly look like a big picture. The factors that affected the sharpness of a photo were as follows: 1. ** The camera factor ** - ** Fixed focus and zoom **: The sharpness of a fixed focus lens is generally higher than that of a zoom lens. Because the number of lenses in a zoom lens was more than that of a fixed-focus lens, it was more difficult to design, and it was easy to produce optical aberrations. The number of lenses would also reduce contrast and increase facula, and the fixed-focus lens usually had a larger aperture than the zoom lens. 2. ** Shooting conditions ** - ** Shutter Speed **: Use a high-speed shutter as much as possible to ensure the sharpness of the photo. When shooting with a hand-held camera, inexperienced photographers would have a higher probability of shooting a fake photo if the shutter speed was set below 1/30s. For telephoto lenses, it is recommended to control the shutter speed beyond (1/focal length). In order to ensure the brightness of the photo, it may be necessary to open a large aperture and lose the "large depth of field" when increasing the shutter speed. It can also be balanced by increasing the USB value. - Aperture: Any lens has imaging errors. Using the largest aperture will expose the lens 'aberrations to the greatest extent, resulting in a decrease in image clarity. Using the smallest aperture will cause light refraction, resulting in a decrease in image clarity. There is an optimal aperture that can improve the image quality. - ** Focus **: Most cameras have an autofocus function, but when the depth of field is particularly small (such as focusing at a close distance to the subject, using a long focal length lens, or using a large aperture to shoot a close-up), the autofocus may not be accurate. You can use manual focus and press the shutter halfway to test whether it is in focus. - ** Depth-of-field **: Depth-of-field depends on the purpose of shooting. Scenery shooting requires a large depth of field, which can be shot with a small aperture, a short focal length lens, and long-distance focusing. Close-up shooting requires a small depth of field, which can be shot with a large aperture, a long focal length lens, and close-distance focusing.

Photographic Tour
The following are some works related to photography: - Li Nanfang's "Seven Laws, Traveling in Europe and Recalling" said,"To and from the iron wings to cross the distant sky, ten days to travel all the way." The Alps were covered in clouds and snow, while Florence was windy on a rainy day. The smoke floated in the castle, and the sunset in Paris rang the evening bell. If you want to travel all over Europe and the West, when will your white head turn green?" He described what he had seen and heard during his trip to Europe, such as the snow in the Alps, the wind and rain in Florence, the castle, and the evening clock in Paris. This could be a memory material for a photography tour. - In Ma Tian's "Seven Laws Autumn Tour", he secretly traveled in the countryside in late autumn, and traveled alone in the old place at dawn. Riding a horse with a whip, galloping on the overlapping peaks, drinking the wind and stepping on the dew to find new fields. Looking at the beauty of the snowy mountain in the distance, looking at the blue sea stream. Sighing that the trees are withered and the grass is messy, I am happy to see the white sheep." It depicted the scenes of a trip in late autumn, such as riding a horse, seeing snowy mountains, blue seas, withered trees, withered grass, and white sheep. If it was used in a photography tour, these scenes would also be very valuable. - Li Nanfang's " Seven Laws·Shangjing Club's group of friends in the west photography reminiscing about the old journey "," The scenery is magnificent and happy, and I don't want to return to the west several times." Longtou Desert stretches thousands of miles, and the peaks beyond the Great Wall are hundreds of miles high. Clouds rose from the mountains and piled up snow, and the water was clear and clear in Qinghai. I love the long river and the setting sun the most." It presented the magnificent scenery of the western tour, such as the desert, the peaks, the snow of Cangshan Mountain, Qinghai Lake, etc. It was a beautiful scenery that could be encountered but not sought after in the photography tour. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Photographic Director
A photography director was a professional role that combined photography and directing work in the creation of media projects such as film and television. From the perspective of photography, one needed to master photography skills, such as portraits, news photography, and other different types of photography skills. For example, when shooting people's documentary interviews, event meetings, studio dialogue programs, and other scenes, one needed to be able to shoot images that met the requirements. From the director's point of view, one had to be creative, interpret the script, and have the ability to work in a team to turn the story into a visual work. Only through directing skills and leadership could one achieve the perfect presentation of artistic creation. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Photographic exposure
What you want to ask might be "photography exposure". In layman's terms, exposure was the amount of light a photo received. Too little light would cause the photo to be under-exposed and dark, while too much light would cause the photo to be over-exposed and white. The exposure was controlled by the three elements of aperture, shutter, and sensitivity: 1. Shutter: The slower the shutter speed (the longer the shutter time), the greater the amount of light entering, and the brighter the photo. Conversely, the faster the shutter speed, the smaller the amount of light entering, and the darker the photo. For example, a high-speed shutter was suitable for capturing fast-moving objects and could freeze a clear picture, while a low-speed shutter could record the trajectory of motion and was used to capture silky water and star trajectories. 2. Light sensitivity: The higher the sensitivity (the more sensitive the camera is to light), the greater the amount of light entering, and the brighter the photo. 3. Aperture: When the sensitivity is constant, the aperture and shutter are in inverse proportion. In addition, there were different ways of exposure: 1. Average exposure method: - The exposure was based on the average light measurement value. The subject was taken as a whole, and the average brightness value of the whole was measured at one time and exposed according to this average value. If the subject has a single tone and the brightness is close to medium gray, or if the subject has a difference in light and dark but the light and dark are evenly matched, a better exposure effect can be obtained. However, when the subject is too bright, too dark, or the light and dark area is too wide and the contrast between light and dark is too large, exposure errors may occur according to the exposure recommended by the light meter. - The average value exposure was to measure the local brightness values of the bright and dark parts of the subject, then average several values, and then expose according to the average value. 2. Regional exposure method: The reflection rate of the scene, the brightness of the scene, the amount of exposure, and the brightness of the image were integrated into 11 gray-scale regions. Level V was the area corresponding to an intermediate gray (18% reflective) object. It was the benchmark for light measurement and exposure. The real areas that could express texture were the seven regions from Level II to Level VIII. 3. High-profile exposure method: It is suitable for the subject to be a bright object with high reflective rate, or most of the subjects are high-brightness objects, such as white, light-colored porcelain, glass, white cloth and other creations, as well as natural scenery such as clouds and snow. The method was to directly measure the brightness of such high-brightness objects, and then increase the exposure by about 3 levels during the exposure, so that the brightness of the image of the bright object fell in the position of Zone VIII. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Photographic Exposed
In photography (such as documentary or environmental portrait photography), a mistake refers to a situation where some minor details are wrong and affect the beauty of the photo. In terms of film and television photography, there were three main categories: the content of the shot was incoherent, the change of characters and props violated logic, and the camera equipment or personnel were photographed. For example, in some movies and television dramas, the photographer entered the camera, modern objects appeared in ancient dramas (such as the street lamps and modern people in the scenes of Nie Feng and Second Dream boating on the river in Wind and Cloud), the actor's clothing logo was not cut off (such as Heroes of the Sui and Tang Dynasties), the mobile phone secretly took pictures during filming, and the classic drama, Journey to the West, Tang Sanzang wearing a modern white shirt and so on. In addition, if there were background interference elements in the photo (such as residential houses, etc.) that affected the theme of the picture, it could also be considered a situation of being exposed. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Photographic Techniques
Here are some photography techniques: 1. Martin Parr: " My ultimate goal is to make the ordinary extraordinary." 2. " Great scenery depends on running hard and observing the weather before going to bed. There is no good light at noon, but good light is in the morning and dusk. The scenery is important to the atmosphere, and the rain and fog are not missed. Bring a camera when it rains, and wait for it to clear up in the evening. Add slow film on the big bottom, and the shutter release of the tripod. Zooming is easy to shine, and try to use fixed focus. Remove the UV-ray mirror and install the hood. The tripod should be locked tightly, and the mirror should be raised in advance. In the landscape measurement, the gray should be reduced in white and black. For long exposure, take a few photos. The negative film should be slightly reduced, and the positive film can be slightly reduced. The wide-angle focuses on the theme, and the long-focus compress the scene."Small aperture depth of field, fully open to paste the background; Take the backlighting on the side of the flower, slow door to show the movement; The stream should be exposed for a long time, continuous and dense; Look for the side light when you see the mountain, and take the reflection when you see the water; Focus on the theme, the level should be flat; Polarized light to remove reflection, gradually flat contrast; If the contrast is too large, the black card effect will be good; Long exposure to avoid car lights, the rocks should be moist; There should be more clouds, mainly cloudless land; The key to the front is the three-point grid; The characters are interesting, and the dragons should be the finishing touch; The scenery should be removed from the sundries, and the garbage should be picked before shooting." 3. "Equipment is important, but it's not everything." 4. " There's only suitable exposure, not accurate exposure." 5. "The most satisfactory piece is the next one." <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
