There were many technical principles involved in satellite photography in space. The first problem was the resolution of the camera. For military reconnaissance satellites, the resolution of the camera was extremely high. For example, the American spy satellites, although some data could not be verified, the resolution was far higher than ordinary cameras. For example, they could see objects the size of license plates. Even the predecessor of the Hubble Space telescope was a spy satellite eliminated by the United States, and the Hubble Space telescope could capture celestial bodies dozens of light-years away, which also reflected the high performance of spy satellite cameras. The second was to solve the stability of the satellite when it was moving at high speed. To get rid of Earth's gravity, the satellite had to at least exceed the first cosmic speed (7.9 kilometers per second). However, because the satellite was far enough from the ground, the relative speed of motion would seem to slow down when shooting. With some anti-shake technology, clear photos could be taken. In addition, early spy satellites used film to take photos. When the film was finished, it would be thrown back to Earth. The film would be wrapped in a heat-resistant protective layer, and the ground reception personnel would use the aircraft to retrieve the film in the air. Modern satellites, on the other hand, took digital photos and sent them back to the ground through wireless communication. If you want to shoot ground video (This is much more difficult than taking pictures), modern remote-sensing satellites (Most of these satellites were in low-Earth orbit about 300 - 400 kilometers from the ground.) In order to obtain long-term video data of a certain location, it was necessary to constantly adjust its attitude in pitch, yawing, and rolling. The satellite would usually be equipped with a reaction force windmill and a magnetic torquer. It also required a small boost method. At the same time, it also required multiple satellites to cooperate with each other to achieve better video capture results. Read more exciting novels for free

Some satellites had captured pictures of dragons, but the " dragons " in these pictures had reasonable scientific explanations that they were not real dragons. For example, in the photos taken by the satellite above Xizang, the real dragon was actually a glacier mountain range. When the glacier moved, it produced scale-like ripples on the surface, which looked like dragon scales from a distance. There was also the dragon-like terrain in Qiandongnan Prefecture of Guizhou Province, which was actually a pattern formed by rivers. There was also the black dragon's back that could be vaguely seen in the photos of Kunlun Mountain taken by the satellite in China. These were not real dragons. The novel " Flood Dragon " is equally exciting. Everyone is welcome to click and read it!
It was difficult to determine which one was more difficult in terms of difficulty. Both had their own difficulties. The following was an analysis from several aspects: ** 1. Creation and expression ** 1. ** Photographer ** - Photographers had to use one photo to express the theme, and even the number of photos was limited. A photo needed to contain a wealth of information, be substantial and eye-catching, capture the audience with the image, and infect the audience with the theme. This required the photographer to capture the appropriate image in an instant, which required the photographer's observation ability, instant composition ability, and grasp of the theme. 2. ** Cameraman ** - A video was used to explain a matter or a story through a video. The duration could range from a few minutes to a few hours or even longer. This required the creator to have good narrative skills, maintain the cohesiveness and logic of the story over a long time span, and arrange the plot development and character movements reasonably. Compared to the instantaneous expression of photography, photography paid more attention to the overall planning of the timeline. ** Second, technical operation ** 1. ** Photographer ** - In terms of operation, the effect was instantaneous. Before pressing the shutter, one needed to consider factors such as composition, light, and focus. For example, composition. Different subjects were suitable for different composition methods. Landscape photography might need to consider the layout of the front, middle, and long range. Character photography needed to consider the position and posture of the person in the picture. The use of light was also crucial. Different angles of light (such as forward, backward, and side light) would produce different effects. The photographer needed to adjust according to the purpose of the shoot. Inaccurate focus could cause the photo to be blurry or the subject to not stand out. - Although many cameras now had autofocus, auto-exposure, and other functions, in order to take high-quality photos, the photographer still needed to master the manual mode and make more precise adjustments. 2. ** Cameraman ** - It was a continuous operation, and the filming process took a period of time. During this time, to ensure that the subject was in an important position on the screen, one needed to consider the way the camera moved (push, pull, shake, shift, follow, etc.), as well as the speed and rhythm of the movement. For example, when shooting a sports event, the camera had to move along with the movements of the athletes, while ensuring the stability of the image and the clarity of the subject. - For multi-camera cameras, one also needed to consider the coordination between different cameras and how to switch the camera to make the story smooth and the visual effect rich. ** 3. Equipment and venue ** 1. ** Photographer ** - In terms of equipment selection, if you were pursuing high-quality photos, you would generally need to choose better equipment such as a full-frame camera. Different lenses were suitable for different shooting scenes. For example, a wide-angle lens was suitable for shooting large scenes, while a telephoto lens was suitable for shooting distant objects or close-up portraits. Although photography was relatively less affected by the location, in some special scenes (such as small spaces or places that required special shooting angles), it was necessary to consider how to place the equipment and adjust the angle. - You can use the camera's own flash to supplement the light when the light is not good, but for some special light effects (such as the light and shadow in night photography), you may need additional lighting equipment. 2. ** Cameraman ** - In terms of equipment, cameras were generally used to shoot. Although the new cameras could also shoot, the imaging effect could not reach the level of cameras. Due to the influence of the filming location, high-quality films often required multiple camera positions. - Cameras required specialized lighting equipment to achieve better film quality in places with poor lighting. There were also many other factors that needed to be considered in the layout of the venue. For example, when shooting an indoor drama, one needed to consider the layout of the lighting, the construction of the scene, the collection of sound, and many other factors to ensure the quality of the video. ** 4. Post-production ** 1. ** Photographer ** - It mainly adjusted the color, contrast, saturation, etc. of the photo. Sometimes, it might be necessary to make simple cuts or remove defects. Although there were many default filter options available, to bring out high-quality, customized photo effects, one still needed to master certain post-production software operation skills, such as Adobe Photoshop. 2. ** Cameraman ** - Post-production was even more complicated. In addition to color correction and editing of the video, they also needed to deal with the sound (such as adding background music, adjusting the volume balance, removing noise, etc.), adding special effects (such as transition effects, visual effects, etc.), and ensuring the compatibility of the video played on different devices. To sum up, photography and photography had their own difficulties and challenges. The difficulty depended on the photographer's skill level, experience, and creative requirements. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The cartoons often show the satellites' shapes and designs in a creative way. They might also depict the satellites' operations and interactions in space.
In China, people who flew into space were called Chinese astronauts. The following are some of the China astronauts who flew into space on a manned spacecraft: Yang Liwei, who successfully launched Shenzhou V on October 15, 2003, becoming the first China visitor to space; Liu Yang and Wang Yaping were China female astronauts. Liu Yang flew into space on Shenzhou 9 on June 16,2012. Wang Yaping was selected as an astronaut for the Shenzhou 10 space mission in April 2013. In 2021, she became the first female astronaut to enter the China space station and perform related tasks. Jing Haipeng and Liu Wang also took the Shenzhou 9 manned spacecraft into space. In addition, there were many batches of astronauts participating in China's manned space missions. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
This question was not very clear. If you wanted to ask how to take pictures, you could refer to the following: First, he adjusted the phone's settings. He opened the "Color and Color Temperatures" option in the "display" and selected "Vivid" to make the photos more colorful. Then, he returned to the settings page and opened the "Smart Assist" and the "Barrier-free" and "Advanced Visual Effects" option to improve the color selection, blurring effect, or lighting effect. Then, he opened the camera settings, adjusted the resolution to the highest (such as 16MP), and opened the "reference line" to facilitate composition. If you want to shoot a person, adjust the photo button to "Portrait" mode to turn on the beauty function and choose the skin level according to your needs. If you want to highlight the blurred background of the person, you can choose "Large Aperture". If you want to shoot a building, you can click "More" on the camera and choose "panoramic photo" or "3D dynamic panoramic photo". You can also choose professional mode or night scene mode according to the environment to take better photos. If you were asking about the pose for the photo, you could cross your legs and block the sun with your hands, open your feet and shoot with your hips, bend your legs and raise your hands high, kick your feet sideways with your hands open, support your hips with your hands to model your ears, bend your legs and open your hands up, and so on. For the environmental portraits, try to open your hands and feet as much as possible, follow the four key words of sitting, walking, standing, and jumping. Medium and close-up portraits can increase the interest of the picture with props. If it was about composition skills, the character should be placed below the upper horizontal line, magnified, and the lens moved far away to shoot the whole body; the character should be placed in the middle and lower two squares, the character should be placed at the three-point line, and the center of gravity of the scene should be placed on the other side; the super practical diagonal composition could be used to make the background form a diagonal line, the character should be placed in the middle to form a sense of extension, and the hands or legs should be extended to form a triangular composition. If the above is not what you want, please clarify the problem. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

As of July 2024, China has at least 901 satellites in orbit. However, the total number of satellites launched over time also needs to consider those that may no longer be in orbit due to various reasons. In 2023, China launched 63 orbit satellites (excluding sub - orbit, failed launches, and virtual satellites). <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Nowadays, most smartphone cameras came with a geographical location fingerprint function that could automatically record the location of the shot. The steps to activate this function on different brands of mobile phones were roughly the same: turn on the phone's camera, find the settings option (the location may be in the upper right corner or at the bottom of the screen), enter the settings interface, find the "geographical location" or "location information" option and turn it on. At the same time, allow the camera to access the location information. This way, when taking a photo or recording a video, the phone can automatically obtain the current location and add it to the photo or video's watermarks. If the phone camera app doesn't support this feature, you can also use third-party camera apps, some of which may provide the function of showing the location of the photo. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
