p Photographic measuring instrument
Photographic measuring instruments were divided into three-dimensional measuring instruments and ground three-dimensional measuring instruments. The three-dimensional measuring instrument is an instrument used in the differential method of aerial photography. It uses a correcting machine to eliminate the influence of photo tilt and aerial height difference on the measurement of height difference between ground points. The ground three-dimensional measuring instrument was one of the instruments used in ground three-dimensional photogrammetry. After the photographic image pair was oriented on the instrument, it could be used for three-dimensional observation. Through the transmission mechanism, it could automatically draw the ground features and contours on the drawing table. This kind of instrument could only deal with upright photography and equal-tilt photography. If equipped with a "tilt calculator", it could also deal with equal-tilt photography.

Downhole photographic instrument
The following information was related to the underground photography instrument: - The underground camera/video recording equipment has the requirements of clear imaging in low illumination, which can maintain the clarity and color of the image under low illumination. It has the function of strong light suppression, which can avoid the strong light caused by the miners 'headlights and environmental lighting, and can be turned on simultaneously under the condition of sufficient environmental lighting. It needs better sealing. For example, the special camera in the underground will be equipped with two chambers to solve the problem of poor sealing. If the sealing is not good, it will cause fog inside the camera and cause the image to be blurred. There are lightweight requirements. Due to the limited underground transportation equipment and installation conditions, the equipment should be as light as possible for transportation and installation; There should be wireless communication requirements, supporting Wifi and 5G communication modes; Dust prevention requirements should be met. Due to the large dust in the underground coal mining face, heading face, belt tunnel transportation and other scenes, the equipment should support self-cleaning; There should be anti-vibration and anti-shake requirements. When installed on equipment such as hydraulic support and tunneler, it can support anti-vibration and anti-shake to ensure stable imaging of video images; It should also have AI analysis requirements, that is, it has AI functions, and can directly load intelligent analysis algorithms to achieve local analysis. - The mine intrinsic safety infrared night vision device was a device that could be used underground. It had the function of remote detection in low light or darkness. The device had the function of taking pictures and recording videos. Underground shooting used electronic sensors to convert optical images into electronic data and store them in digital memory cards. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Speckle measuring instrument photography
Different speckles had different requirements and characteristics. For example, when the seventh generation of Visia was tested, it would test the left, right, and left sides and then take photos. During the test, it was not allowed to apply any sun protection or makeup, and it had to be cleaned before the test. When the AI intelligent skin detector was used, it would take photos in different directions according to the prompts, and it needed to remove makeup before the test. There were other related devices on the market, such as smart skin detection and freckle removal devices, but there was no mention of special requirements for photography. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The tripod of the instrument
A tripod was a support frame used to stabilize instruments such as cameras. It was made of various materials, including wood, high-strength plastic, alloy, steel, volcanic rock, carbon fiber, and so on. It played a significant role in a variety of photography scenes, whether it was for amateur or professional users. For photography, the main functions of a tripod were as follows: 1. ** provides stability **: This is the most basic and important function of a tripod. In the case of long exposure times, such as shooting night scenes or pictures with surging trajectories (star tracks, flowing water, etc.), macro shooting, and when the light was insufficient and low sensitivity and high quality were needed, the camera must be stable for a long exposure time. A tripod could meet this requirement. 2. [Changing the way you think about shooting: Let the photographer slow down and take the shot calmly.] The user would have more time to think about the angle, composition, and wait for the best lighting and timing. This would help to take higher-quality photos. It was a change from mentality to shooting style. In addition to traditional tripods, there were also some special tripods or devices with similar functions: 1. ** Tree Tripod **: When shooting outdoors, if you don't have a tripod, you can make it yourself with a strong glue and a tree branch to achieve the effect of stabilizing the camera. 2. ** MAMPOD Mini Tripod **: This is a tripod designed for city scenery photographers. It has the function of a powerful clamp. It can be used with railings, a clamp, a table top, a hook, and a hand-held mode. One of its legs had a foldable clamp that could clamp a cylindrical or flat object of a certain size. Although its stability was not as good as a traditional tabletop tripod, and its strength and opening and closing distance were not as good as a powerful clamp, it integrated the two functions together and effectively reduced the weight. In addition, there are different brands, different models, and different prices of tripod products on the market, such as Zoubi, Leina, Youlan, Miliboo, Manfrotto, Imprint, Futubao and other brands of tripod or head products to choose from. There was also a special-purpose tripod like the M3 tripod, which was specially designed for the heavy machine guns of the American military. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Photographic Distortion
Based on context alone Distortion was a common phenomenon in photography. ** 1. Distortion caused by the camera lens ** 1. ** Wide-angle lens ** - The wide-angle lens would produce perspective distortion when shooting. This kind of lens had a wide angle of view. When shooting close-up objects, the objects at the edge of the picture might be stretched and deformed. For example, when shooting a building, the edges of the building might bend outward. If this distortion was not paid attention to in architectural photography, it might affect the authenticity of the building's appearance. - At the same time, when the wide-angle lens shot a character, the parts of the character near the edge of the picture (such as hands, feet, etc.) might appear larger than normal, resulting in an exaggerated effect. 2. ** Telephoto lens ** - A telephoto lens could also cause distortion, but it was different from a wide-angle lens. The compression effect of a telephoto lens would make the spatial relationship between objects appear to be compressed. For example, when shooting a landscape, the distance between a distant mountain and a nearby tree would appear closer than the actual distance. This distortion might need to be considered in some scenes that needed to express spatial levels. ** 2. Distortion caused by shooting angle ** 1. ** Upwards ** - When shooting a tall object (such as a tall building or a big tree) from above, it would cause the object to have a narrow bottom and a wide top. This kind of transformation could be used for creative photography. For example, when shooting a towering skyscraper, an upward-facing shot could enhance the towering feeling of the building and make it look more majestic. However, if it was in the case of building measurement or the need to accurately represent the proportion of the building, this kind of distortion needed to be avoided or corrected later. 2. ** Aerial Shot ** - When shooting from above, the object may have a narrow top and wide bottom. For example, if you were to shoot a crowd in a square, shooting from a high position might cause the shape of the crowd in the picture to appear as if the top of the crowd was shrinking inward. ** 3. Transformation in post-processing ** 1. ** Cutting and Stretching ** - In the post-processing software, improper trimming or stretching operations could cause the image to be deformed. For example, if the image was stretched too much to adjust the composition, the proportion of the object in the image might be out of balance, and the originally round object might become oval. 2. ** Inappropriate use of correction tools ** - Although many post-production software had x-ray correction tools, if they were not used properly, such as over-correction or correction in the wrong direction, it would also cause new distortions. For example, when correcting the inclination of a building, if the correction parameters were set incorrectly, the building might be deformed in other directions. <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 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>
Photographic Gold
The prime time for photography was usually one hour after sunrise and about one hour before sunset. During this time, the light was rich and colorful, the angle was low, and the atmosphere was better. There was also a saying that 4 - 6 pm was the prime time for photography, but it was more accurate to say that it was the first hour after sunrise and the last hour before sunset. The exact duration depended on the weather, location, and other factors. Near the equator, the golden time often lasted for one to two hours, and there was little change in winter and summer. However, near the North Pole or the South Pole, the golden time would be different and last longer. The light produced during prime time was relatively soft, and there would be no glaring shadows. The overall look was very warm and pleasing. It was suitable for shooting people, wild animals, birds, and many other objects. The light had different effects such as background light, back light, and edge light, which could be used for different creative shooting. However, primetime was not suitable for all types of photography. For example, street photographers might prefer to shoot at noon, and macro photographers might prefer to shoot on cloudy days to capture color saturation and rich details. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Photographic Symbol
Photographic symbolism is an important means of expression in the art of photography. The Connotation of Symbols 1. ** Concept definition ** - Symbolism is to use the overall characteristics of an image to express or imply the metaphor meaning of another thing. It is the reflection of things, the metaphor of things, the comparison and hint of truth. This was the transcendental meaning that the aesthetic subject gave to the object. It was a kind of hidden meaning. - In photography, symbols used intuitive visual language as a symbol, and condensed and expressive images as a medium to compare and hint at the aesthetic meaning of the subject. 2. ** Symbol classification ** - ** By way of thinking ** - ** Symbolism **: In the artistic image created by the author, the symbolized body (main body) and the symbolic body (accompanying body) have the same relationship. The symbolic body will strengthen the aesthetic content of the main body from the front. For example, with the capital "person" formed by the crossed arms of a man and a woman as the main body and the bright red rose as the symbolic image, people could sublimate the aesthetic ideals of human love, motherland love, and eternal peace. - ** Countercurrent Symbol **: The symbolic body does not create the value of the main body in a positive way, but in a movement that contradicts the relationship between the main body and the symbolic body. For example, the main body of the picture was a haggard middle-aged woman who was in extreme pain because of her desire. The background was a still photo of the "Love of Bao and Dai" as a symbol, which strongly reflected the pain, lonely soul, and heavy burden of life of the main body. It had the aesthetic effect of "pipa rebound." - ** From the composition of the image ** - ** Individual Symbol **: Use a single element (concrete or abstract) in reality that is related to the main body as a symbol to excavate its symbolic meaning. - There were also compound symbols, partial symbols, and overall symbols. Second, the symbolic meaning of each element in photography 1. ** Natural Elements ** - [The sun symbolizes light, warmth, and the power of life.] In the pictures, their appearance often gave people courage and confidence, dispelling the darkness and illuminating the road ahead. - Water is the source of life. It symbolizes flow, change, and the continuation of life. When it appears in different forms such as a quiet lake, a surging waterfall, and a rapid river, it gives people vitality and hope, arousing people's praise for nature. - Trees often symbolize growth and tenacious vitality. Their deep roots and luxuriant leaves give people hope and strength. He could take pictures of the entire tree or parts of the tree, such as the roots, trunk, branches, and leaves. He could also use them as a companion to express his understanding of life. - ** Flower **: It represents the power of beauty, purity, and love. Its blooming and fragrance bring joy and satisfaction to people, triggering people's longing and pursuit of a better life and happy times. - Mountains and rivers symbolized lofty, broad, and strong power. They were often used to represent magnificent scenery and great spirit. Their precipitousness and magnificence shocked people, triggering people's imagination, awe, and exploration of nature. 2. ** Character Image ** - ** Lonely character image **: Often deeply touching, representing the complexity and fragility of the human inner world, triggering the viewer's thinking about life and existence. - ** Laughing Character Image **: It is often used to express the power of happiness, happiness, and friendship, giving people warmth and joy. It represents the beauty and happiness of the human inner world, triggering the audience's praise and cherish of life and love. - [Meditating character image: It is often used to represent the power of thinking, reflection, and exploration. It often gives people a deep feeling and represents the depth of the human inner world.] 3. ** Social Elements ** - ** Cityscape **: It is the symbol of modern society. The scene of high-rise buildings and heavy traffic is shocking and amazing. It represents the power of prosperity, progress, and modernisation. - [Ruins: Often used to represent the accumulation of history and the disappearance of civilization.] - Street: It is an important space for people's daily lives and represents the current state of social development. In short, the symbolic expression in photography conveyed a specific meaning through the scenes and elements presented in the image, reflecting the photographer's perception, emotions, and thoughts of the world. This helped the viewer to deeply understand and appreciate the rich content of the photo. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
