Can you use an underwater camera in muddy water?
Using an underwater camera in muddy water had certain limitations, but there were also some solutions. Some underwater cameras did not work well in muddy water. For example, a camera that did not support the deep sensing of heat would see a much worse picture in muddy water than in clear water, and the image quality would be greatly affected. However, there were also cameras that were specially optimized for turbid water imaging effects. For example, the underwater camera of Hikvision used underwater full-color fog transmission technology, which could effectively improve the imaging effect in turbid water. In addition, some auxiliary methods could also be used to improve the shooting situation in turbid water. For example, using a tethered underwater remote-controlled robot or an autonomous underwater robot equipped with a turbid water reduction device, the turbid water in the target observation area could be reduced by spraying water at the target observation area, thereby assisting the camera to better shoot in turbid water.

Blind underwater camera shots
Underwater camera blind shooting was a technique to shoot underwater scenes without looking directly at the viewfinder or display screen. This required the cameraman to rely on experience and pre-judgment of the scene to operate the camera. There were a few factors that needed to be taken into consideration when shooting underwater. The first was the equipment settings, such as setting the appropriate aperture, shutter speed, and so on. Due to the complexity of the underwater environment, the lighting conditions may change. A large aperture (such as a small aperture value, such as f/2.8, etc.) can increase the amount of light entering and blur the background to a certain extent. A fast shutter speed (such as 1/500 seconds or more) can help capture fast-moving objects and avoid blurring the picture. The USB can be set to a value that can ensure the image quality and enough exposure according to the camera performance and lighting conditions, such as USB 200 - 400 (low USB can reduce noise). Secondly, he had to make a pre-judgment about the scene. For example, when taking pictures of underwater creatures, one had to understand their activity patterns and habits, know their possible locations and swimming directions, and then aim the camera at the corresponding area for blind photography. In the case of water flow, the impact of water flow on the subject and the stability of the camera also needed to be considered. Furthermore, the camera's operating skills were also very important. For example, he could determine the angle and distance range of the camera in advance, and control the camera's grip and movement trajectory to cover the scene he wanted to capture as much as possible. If you were using underwater photography equipment with a remote control function, you would also need to be familiar with the remote control operation to accurately trigger the shutter during blind shooting. In addition, different underwater environments such as oceans, lakes, swimming pools, etc., had different water quality, light refraction, and scattering, which would affect the effect of blind photography. The photographer needed to adjust and adapt to different environments. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The role of storing clear water and expelling muddy water
The main functions of storing clear water and draining muddy water were as follows: In terms of controlling the Yellow River's silt, the Yellow River's silt content was high and it was difficult to control it. The technology of storing clear water and draining muddy water could help solve the silt problem. In the Sanmenxia Project, this technology allowed the silt in the reservoir area to reach a balance between the annual intake and discharge, maintaining a long-term effective storage capacity. For the Yangtze River Three Gorge Project, although the silt content of the Yangtze River was much lower than that of the Yellow River, it might also have a silt siltation problem similar to that of the Sanmenxia Reservoir over time. The method of storing clear water and draining muddy water could store clear water and discharge muddy water, preventing the reservoir from becoming a mud reservoir, providing an effective solution for the silt treatment of large-scale water control projects. The construction of large-scale water control projects such as Xiaolangdi of the Yellow River and the Three Gorge of the Yangtze River drew lessons from the experience of storing clear water and draining muddy water in the Sanmenxia Project. It opened up a "testing ground" for the world's river silt control and water science and technology research and development, providing a plan for reference.
The time of storing clear water and draining muddy water in the Yellow River
In the Sanmenxia Project, the unique application method of "storing clear water and draining muddy water" was used for flood discharge and sand discharge in flood season, and water storage in non-flood season. Through this method, the imbalance of water and sand was changed to the adaptation of water and sand, so that the sand in the entire reservoir area was balanced in and out of the year.

Then, beyond life and death, beyond heaven and earth, beyond time, what awaits us? 12:"This Game Is Too Real": This is the first book I read by Chen Xing. At first, I felt that it had a faint taste of "Super God Mechanic". Perhaps it was because of the setting. In short, the content was good, but I felt an inexplicable sense of impulsiveness when I reached chapter 180. Perhaps it was because of me, so I should push this book to everyone. Those who don't like to follow updates suggest to wait a little longer. This book is a little short. "Red Heart Sky Patrol": In ancient times, the demon race went extinct.

What was there was only a weapon of thought that shocked the world and readers. It was hard to imagine that the political and economic content that could not be learned in school, even the philosophical content, could be turned into words like a stream of spring water by the author's pen, silently nourishing things. There was no Jiang Xing Huo who was afraid of death in this world. There was only Teacher Jiang who sacrificed himself for the truth. Perhaps this was the Ming Dynasty's version of "The Age of Awakening." "Ascending on a Better Day" was a book that made people's eyes light up.

It's just that the comments are as if they can't quit after getting high... But it's really well written "Deep Sea Ember": Recently recommended work. The first three chapters might not be particularly surprising, but the author's work did not care about the golden chapters. The author's storytelling rhythm was very good. You just need to be a little more patient and read slowly. Actually, when I read chapter 10, I was already very interested in this story. This process, from chapter 1 to chapter 10, was a process of increasing anticipation. When you see chapter 10, you won't think about saving this work anymore. You'll just have a sense of anticipation. You'll want to catch up and see the latest chapter as soon as possible. The writing is good, the story rhythm is also very good, and there is a very big world view, and a stable update time... Isn't this worth reading? "Cultivation in the Chaos of the Demonic Martial Arts".<strong></strong><strong></strong> He basically maintained the standard of grain and fodder, and the settings were generally better than his own. The main character's attributes were maxed out, so he did not have to worry about brainless plot conflicts to guide the plot development. [Work Information]: Title: <Gou Cultivation in the Demonic Martial World> [Author: Transcriptionist (Old God)] [Status: Series in progress] Tagged: Xianxia, Heavens, Longevity [Rating: 4] [Goldfinger]: 1.

By planting trees to obtain longevity [Plot Introduction: Fang Xi, who has transmigrated to the cultivation world, has the ability to transmigrate to other worlds.] Relying on his own cautiousness and the ability to travel through the heavens, he slowly enjoyed the joy of cultivating. "Who told him to cultivate!" Who told him to cultivate? Author: The Whitest Crow [Temporarily Set: Food and fodder] [Anticipation: 3.5 - 4 stars] 1. The new works of the authors of the Dacheng period were still in a serious and amusing style. 2. The cultivation system was still the same as before, but from the progress of the character from mortal to foundation establishment in two chapters, you could tell that this was definitely not an ordinary leveling immortal cultivation text. 3. Perhaps because of the outline, the opening chapter was much smoother than the previous one. In addition to the high-quality storyline as usual (the entrance test of the River Spirit and the examiner, the nonsensical teaching of Big Sister, the elements of solving the case of the Painted Ghost, etc.), the overall reading experience was very comfortable and interesting. 4. The background of the Otherworld was also more creative. Whether it was the related settings of the Chamber of Commerce (and even insurance), the various facilities and missions in Dao Seeking Sect, or the various vivid demons and ghosts, they all greatly enriched the details of this cultivation world. <strong></strong> In this era of chaos, the Great Era was about to descend. It was highly recommended for those who had watched the previous game and felt that it was not enough. If you haven't seen the previous game, but want to see something light and interesting, it's also recommended to try it out. The reasonable party or the readers who only wanted to read the traditional upgraded cultivation novels should be cautious. [Picture] You can read these novels on Qidian Chinese Network.
Explanation on the process of storing clear water and draining muddy water in the Three Gorge
Storing clean water and draining muddy water was a technical method to deal with the problem of silt. Taking the Sanmenxia Project of the Yellow River as an example, it formed a unique application method of "storing clear water and expelling muddy water" after exploration, that is, flood discharge and discharge of sand in flood season, and water storage in non-flood season, so as to change the imbalance of water and sand into adaptation of water and sand, and realize the balance of sand in and out of the entire reservoir area during the year. The Three Gorge Project also used the method of storing clear water and draining muddy water to deal with the problem of silt siltation. In the Three Gorge Project, specifically, the flood discharge gate of the Three Gorge Dam was opened during the flood season, and the power of the flood was used to wash the silt deposited in the reservoir area downstream. The cost of this method was relatively low and could achieve obvious results, but it might have a certain impact on the downstream river and ecological environment.

What is the use of the camera?
Cameras were originally used for film and television production, but they are now commonplace. Its uses include, but are not limited to, the following: - In the home, the camera, which was light and easy to operate, could be used for daily dynamic video recording and still shooting, becoming an essential household electrical item. - In terms of highway management, cameras set up by relevant departments could be used to monitor road conditions; cameras set up by high-speed traffic police departments could not only monitor road conditions, but also collect evidence for road traffic violation. - It can be used for publicity purposes in the unit. - It could be used for filming in wedding scenes. - In some special scenes, such as Lego disney cameras, multi-planar cameras could be used to shoot animations, increase the sense of space, and make the animations more realistic and natural. - In terms of scientific research, cameras could be used to study the movement of horses 'hooves when they ran, and they could also be used to film the movement of planets. In film production, the camera can be used to follow an action, or to change the way the scene, person, or object is presented. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The use of camera buttons
Here are some common camera buttons: 1. ** Power On Key **: The on position indicates power on, and the off position indicates power off. 2. ** Mode Wheel **: By rotating it, you can control a variety of shooting modes, such as M, Shutter priority (LV), Aperture priority (TV), camera mode, etc. The white bar on the wheel is the current shooting mode. 3. ** Main dial **: In the case of manual gear (M), it is mainly used to control the shutter speed and adjust the exposure. 4. ** The Menu button **: Located next to the camera's viewfinder, it can be used to set various parameters of the camera or connect the phone to take a selfie. 5. Rate key: It is used to rate the photos in the camera. Pressing it once will give one star, twice will give two stars, and a maximum of three stars. It helps to directly display the star photos when you import them into the QR (batch photo adjustment software), saving time in the later stages of film selection. 6. ** END key **: Press this key to display the relevant information during shooting, such as aperture, shutter speed, sensitivity, exposure ruler, etc. It can also be used to switch between the display viewfinder and the viewfinder. 7. **Q key **: Speed control button, mainly used to control the touch of the screen. When you want to adjust the image parameters, press this key first to directly touch the screen to adjust the parameters. 8. ** Magnifier button **: It looks like a magnifying glass and can be used to enlarge the photo to see the details. 9. ** Playback button **: It is used to view the photos that have been taken. 10. ** Video/photo switch button **: The camera symbol is used to take photos, and the camera symbol is used to record videos. 11. ** Automatic focus on **: Turn on the automatic focus function. 12. ** Automatic focus point selection/zooming button **: It is used to select the automatic focus point or enlarge the image. 13. ** View finder/LCD display switch **: You can switch the view mode between the view finder and the LCD display. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The use of camera angles
There were several ways to use camera angles and their effects: * * 1. Horizontal angle ** 1. * * Natural effects and x-ray vision ** - The angle of the flat shot was close to the human visual habit, and it could present a more natural perspective effect, which could avoid the distortion of the subject due to perspective distortion. 2. * * Picture effects and creative elements ** - In terms of visual effects, although flat shots were more conventional, some creative techniques could be used to make the image more attractive, such as using contrast effects such as size, reality, and color to enhance the layering and spatial sense of the image. * * 2. Overlooking angle (including oblique angle)** 1. * * Emotional expression and architectural shooting ** - A bird's eye view can show gloomy and depressed emotions, and it is generally negative. However, when shooting buildings, an overhead shot could enhance the three-dimensional and layered feeling. 2. * * It is suitable for the scene and effect enhancement ** - It was more suitable for shooting big scenes such as cities and scenery. When using a wide-angle lens to shoot from above, due to its large angle of view, it would further enhance the image effect. In addition, when shooting a portrait from above, it would be affected by the distance, so it could get a cute headshot effect. * * 3. Upward angle ** 1. * * Visual impact and transformation effect ** - Upper-angle photography was when the camera was shooting from a lower angle than the subject, observing and shooting from bottom to top. This angle would cause the main body to be wide at the bottom and narrow at the top to produce a distortion effect. This distortion was even more obvious when using a wide-angle lens. The photographer could use this exaggerated distortion to enhance the visual impact of the picture. 2. * * Perfect for shooting ** - It was suitable for shooting tall buildings to show the height and momentum of the object. It was also suitable for shooting portraits, such as women who were not tall but had temperament. It could give an abstract long leg effect. * * 4. Aerial View ** - A bird 's-eye view required the camera to shoot from above the subject, allowing the audience to see a whole new perspective. * * 5. High angle ** - High-angle shots didn't require specific conditions like bird 's-eye views, and they could bring a unique visual experience to the picture. * * 6. Low angle ** 1. * * Sense of immersion and space ** - A low-angle shot is shot below the level of the subject's line of sight and upward. This angle could enhance the sense of immersion in the photo, fully displaying the three-dimensional feeling of the front and back space, allowing the audience to have the perspective of the audience in the ground world. 2. * * Creation of suspense and control of prospects ** - It was often used to create suspense in movies, such as shooting mysterious characters with only the rhythm of their footsteps. In photography, one should pay attention to the control of the photo's prospects. You can use the ground texture, fallen leaves, and other prospects to guide the direction of the line of sight to make the picture more vivid and interesting. You can also shoot the reflection symmetrical effect. * * 7. Subjective perspective (mainly in the horizontal direction)** - The subjective point of view was what the person in question saw. It could give the person a feeling of being there and was suitable for vlogs. * * 8. Subjective perspective (related to but different from subjective perspective)** - The biggest difference between viewing the world from the perspective of the main character in the scene and the subjective point of view was that the subjective point of view had the character itself as the background, which could also express relationships. * * 9. Omni-directional shooting angle (a special shooting angle technique)** - It was not recommended to use the panoramic shooting function of the mobile phone camera. Instead, it was recommended to use the split-film method. A photo was divided into nine equal parts for nine shots (there were overlapping parts between each photo), and then combined with the post-production software to get a panoramic photo effect with a large sense of space from top to bottom and left to right. However, the color and picture purity needed to be adjusted later. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
