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.

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 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>
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 measurement
Photogrammetry was a technique that used a combination of a camera and film to measure the shape, size, and spatial position of a target. It used the image of the object to reconstruct the spatial position and three-dimensional shape of the object, thereby obtaining the spatial information of the ground or other objects. The core problem was to use the two-dimensional image to obtain the three-dimensional coordinates of the target. Since the invention of photography by Nippes and Dayle in 1839, photogrammetry had a history of more than 170 years. It had gone through three stages: simulation photogrammetry, analytical photogrammetry, and digital photogrammetry. In modern times, the principle of photogrammetry was similar to a puzzle. By capturing and stitching image information to create a digital model of the physical world, images were like " puzzle pieces." The more images captured and collected, the more realistic and detailed the 3D model. The effect depended on the quality of the data set, so the correct shooting method was very important. Photogrammetry is divided into aerial photogrammetry and ground photogrammetry. Aerial photosurveying placed the camera in the air for large or difficult to access areas. It was one of the widely used methods of establishing a geographical database in the field of forest and natural resource management. Ground photosurveying focused on the focus of the measurement object, usually relying on images taken by a hand-held camera or a camera fixed on a tripod. It could quickly collect field data and capture more detailed images. There was also a professional term like control point in photogrammetry. It was a control point that was directly measured on the spot for photogrammetry encryption or map measurement. It was the basis for photogrammetry control encryption and map measurement. It could correct errors caused by many factors. According to the use, it was divided into plane point, elevation point, or flat point, and there were corresponding selection and measurement requirements. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

photographic sleeve
The photographic sleeve was a kind of accessory related to photography. In the field of single-lens reflex photography, there were many kinds of photography sleeves, such as the Thunder Dragon single-lens reflex camera's transfer ring, the direct-focus photography sleeve, the 1.25-inch interface, the astronomical connection telescope accessories, the short sleeve, etc. Different brands and models of photography sleeves had different functions and applications. Some were used to connect the telescope to the single-lens reflex camera (for example, some of the photography sleeves of Star Trang could be used to connect the astronomical telescope to the single-lens reflex camera for astronomical photography), while others were used as transfer rings or extension tubes. <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>
