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 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 equipment
Burning equipment was a common phenomenon among photography enthusiasts. In terms of equipment types, photographic equipment included cameras, lenses, and related accessories. For example, in terms of cameras, there was a huge difference in price and performance from entry-level to high-end models. For example, the first generation of the SonyA7C may feel that their equipment is lagging behind when the new model is launched soon after they get it. There were also many choices for lenses. The prices of lenses with different focal lengths and apertures were significantly different. Some lenses, such as the Canon's 50mm f1.8 " small spittoon " version of the radio frequency lens, had skyrocketed in price. The second-hand price was even close to double the normal price of a new lens. The price of a new lens on sale was even more outrageous. Despite its ordinary design, cheap materials, and conventional specifications, the price still soared. In the field of drone photography, this situation also existed in different models of Djiang. For example, the D.J. mini2, mini3Pro, Royal 3, etc. Every upgrade attracted photography enthusiasts to change their equipment in pursuit of better shooting effects. For example, the mini3Pro was larger than the mini2, with a larger LCD, a non-destructive vertical camera, and a small white camera. However, there were also problems such as lens fog, while the Royal 3 might attract enthusiasts to upgrade because of better shooting effects. However, this series of equipment updates meant continuous investment in funds. Some portable cameras, such as the Fuji X100 series, had average performance. They didn't have super image quality, a powerful focusing system, and negligible anti-shake, but their prices rose from a few thousand yuan to more than ten thousand yuan. Ricoh's GH series, although it had the advantage of being portable and targeted for street photography, its image quality, focus, and battery life were ordinary. The new model didn't upgrade its highlight technology. It added a filter and sold it as a new model. Soon after it went on the market, the price rose by one or two thousand yuan. There was also the SonyRX100M7 card camera, which cost more than 10,000 yuan. This showed that in the field of photographic equipment, price and performance did not always match, but there were still many photographers who were willing to invest money, thus showing the phenomenon of " burning equipment." <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 the first hour after sunrise and the last hour before sunset. At this time, the light was rich in color, the angle was low, and the atmosphere was better. The light was softer and there were no glaring shadows. Overall, it looked very warm and likable. However, it was important to note that primetime was not suitable for all types of photography. For example, street photographers preferred contrasting images and would shoot at noon, while some macro photographers preferred to shoot on cloudy days in order to capture color saturation and rich details. In addition, according to the degree of cloud cover in the sky, the golden time might change or even not appear. Near the equator, the golden time usually lasted for one to two hours, and the interval between winter and summer did not change much, but if it was near the North Pole or the South Pole, the golden time would be very different and last longer. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
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>
