Photographic rail maintenance
For the maintenance of the photography guide rail, taking the guide rail of the photo machine as an example, the following are the maintenance operations: 1. Cultivate a good maintenance habit. Every day after the machine is used, wipe the dirt on the guide rail with a clean cloth or a non-shedding tissue dipped in alcohol, and then wipe the guide rail with a clean cloth or tissue dipped in a little sewing machine oil. 2. When the photo machine was turned on for testing, the car would move back and forth several times after the power was turned on. The dirt in the guide rail would remain on the guide rail. The operation of wiping the dirt several times would be repeated, and then wiped with a tissue or rag to keep the surface of the guide rail clean and the car moving smoothly. 3. Take the Phantom H1 high-end four-head photo camera as an example. The guide rails were maintained with grease every week. Read more exciting novels for free
Photographic equipment maintenance system
The following is a photographic equipment maintenance system: ** 1. Cleaning ** 1. ** Cleaning tool selection and precautions ** - Cleaning the photographic equipment should use suitable tools, such as air blowing, lens cloth, lens cleaner, cotton swabs, wet towels, etc. It is strictly forbidden to use mouth blowing, finger wiping, or other unprofessional tools to avoid scratches or pollution. - Cleaning liquids, wet towels, and other cleaning supplies should not be overused, and expired or deteriorated cleaning tools should not be used. 2. ** Cleaning sequence and steps ** - Cleaning should be done in a certain order, generally from outside to inside, from big to small, from light to heavy. - Cleaning the camera body: First use the air to blow off the dust and hard particles on the surface, then wipe the entire surface of the camera body with a wet towel. For parts that are difficult to clean, such as gaps and bayonet, you can use cotton swabs and cleaners for fixed-point cleaning. - Cleaning the lens: First use air to blow off the dust and hard particles on the lens, then use the lens cloth and lens cleaner to carry out a deep cleaning. Wrapped the cleaning cloth with lens agent on your fingers, and then wiped the lens from the center of the lens in the same direction at a constant speed. For lenses that are deep inside the bayonet, you can use a microfiber lens cloth wrapped in a cotton swab to clean them. - [Cleaning of the sensor: It must be done in a dust-free environment and must be done very carefully.] First, check if there is any dust or stain on the sensor (set the camera to full aperture, the highest IS value, manual focus infinity, and take a photo against a pure white background. Then, enlarge it to check if there are any black spots). If there is dust or stains, you can use a professional sensor cleaning kit to gently and quickly wipe it according to the instructions. If you are not sure if it can be operated, you should send it to a professional after-sales service. At the same time, cleaning should be avoided in a strong wind or dusty environment. Do not spray any liquid directly on the camera or lens (indirectly). ** 2. Storage ** 1. ** Storage location and container selection ** - The photographic equipment should be stored in a suitable place and container, such as a waterproof box, a waterproof cabinet, a sealed box, etc. Do not place the equipment in direct sunlight, high temperature, high humidity, electromagnetic interference, or dusty places. 2. ** Storage method and posture ** - Storage: Turn off the camera and remove the battery (if not used for a long time). Place it in a waterproof box covered with a soft cloth or styrofoam. When possible, the camera could be stored together with the commonly used lens, and a U-shaped inner lining layer (foam board would also work) could be added to the connection to support the lens. - Single lens storage: Lock the lens hood upside down and cover the front and rear covers. Place the lens upside down in a separate space in the moisture proof box. At the same time, he adjusted the focus ring to infinity and shrunk the zoom lens to the shortest position, fixing it with the lock button. - Storage of batteries: Batteries of different brands or models cannot be mixed or stored together, and the humidity in the moisture proof box or cabinet should be checked regularly (generally, it is recommended to store them at a humidity of about 50%). If the moisture absorption card or the drying agent is used, it must be replaced or disposed of in time; if the electronic moisture proof box or moisture proof cabinet is used, it must be powered on at all times to avoid power failure. ** 3. Protection during use ** 1. ** Screen Protection ** - It was to prevent fingers from touching the lens to prevent fingerprints and grease from affecting the paint coating and imaging of the lens. avoid contact with saliva or water stains, and avoid contact with pink gloves (during daily shooting, it is recommended to use bare hands or gloves that have never touched the patient). Move quickly when changing the lens, avoid the wind and dust, and cover the lens cover in time when not in use. The lens can be protected by adding a UV-lens (Ultraviolet filter) and a hood. 2. ** Airframe Protection ** - Water Repellent: When water flows into the interior of the camera, it is easy to cause a short circuit. The temperature difference is easy to produce condensation. When shooting in low temperature environments, it is recommended to wear a cold-proof thermal cover for the camera. When the camera is not in use, put it in a special drying box or place a drying agent in the locker to avoid moisture. - [Protect from dirt: Move quickly when changing lenses. Face the camera down. Pay attention to avoiding the wind to prevent dust from entering the camera.] Do not wear pink gloves during daily clinical imaging, and do not cross infect the patient. - Shock absorption: When shooting, try to hang the camera around your neck to prevent the camera from falling due to instability. When placing the camera, find a stable place to place it to prevent the camera from falling off due to unstable support. - LCD screen protection: To prevent the color LCD screen from being scratched by hard objects, you can consider using a protective sticker. - Protection of the camera card: Do not hot-plug it, do not plug the camera card when it is turned on, so as to avoid damage to the digital products and data loss. It was recommended to have an extra camera card, just in case. A large number of clinical images were recorded in the camera card, and it was necessary to develop the habit of backing up regularly. When the memory card is not in the camera, pay attention to prevent bending, to avoid falling and heavy blows. When inserting the camera card, aim at the card slot. Don't be violent or impatient. Don't damage the card slot interface or bend the camera card pin. <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>
