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. Read more exciting novels for free
panoramic camera distortion
The image distance of the panoramic camera was constant, and the object distance increased with the increase of the scanning angle, resulting in the distortion of the image gradually reducing from the center to the two sides. This distortion existed in the frame sensor. The scanning sensor produced an elevation projection difference and a distortion of the angular ratio. It could also be said that panoramic distortion existed in sensors that were similar to point light sources to obtain information. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The perspective distortion of the camera lens
The perspective distortion referred to the change in relative size and position between objects in the shot. Its main characteristic was "near big, far small". For example, when shooting a road, the distant road would get closer and closer to finally converge into a point. Similarly, the closer the lens was to the subject, the larger the subject appeared. The further away from the subject, the smaller the size change in the appearance of the subject. For example, train windows, the change between the windows closer to the lens was obviously larger than the change between the windows far from the lens. The change in size between the windows was smaller the further back. The perspective distortion was only related to the shooting distance and had nothing to do with the focal length. However, in actual shooting, in order to maintain the same size of the subject, different focal length lenses needed to adjust the shooting distance, which would cause differences in perspective distortion. Generally speaking, a wide-angle lens needed to be shot close to the subject, so the perspective distortion was large. A telephoto lens needed to be shot far away from the subject, so the perspective distortion was small. A short focal length (such as 18mm) would produce a wide perspective, and the objects in the picture would appear to be far away, resulting in strong perspective distortion. This distortion was more obvious when shooting buildings with straight lines; a long focal length (such as 200mm) could eliminate or reduce perspective distortion, making the objects in the picture more realistic. In addition, different shooting methods and equipment would also affect the perspective distortion. For example, using a large frame shiftable camera and shiftable lens to shoot could effectively prevent perspective distortion; finding a suitable height to shoot to ensure that the camera lens was parallel to the vertical line of the building to avoid building distortion; post-adjustment could also deal with perspective distortion. <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 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>
