I recommend " Something's Wrong with This Assassin ". This book is awesome! The male protagonist, Fang Bie, was reborn in ancient times and adopted by the assassin teacher. He was very diligent, studious, and cautious. Martial arts were extremely prosperous in that world, and everyone practiced martial arts. In order not to be treated as the dregs of cultivation, one should not practice martial arts hard. The female lead, Xue Ling, was a young girl of the Jinyiwei, and her background was pitiful. The supporting roles also had their own characteristics, like He Ping, Shang Jiu Ge, and so on. This was a wuxia novel. The writing style was excellent, the plot was interesting, and it had the taste of ancient dragons. The characters were extremely vivid, each with a distinct personality, especially the supporting characters. Although the protagonist was an assassin, he was afraid of death. This setting was very interesting. The plot was slightly slower, but it didn't affect the story. The story unfolded from a unique perspective, as if it was describing the events from the perspective of a supporting character. Moreover, this book combined the style of light novels with the theme of martial arts. It was very unique. Although there were some small problems, such as the fighting scenes being slightly weak and the updates being slow, overall, it was a martial arts novel worth reading.

From a physical point of view, the flight principle of dragons (including flood dragons) could be as follows: - Floating principle: If a dragon was made of a substance with a density similar to air, or if there was a cavity with a large enough capacity inside its body, and it could store gases that were lighter than air such as hydrogen or helium, making the dragon's overall density similar to air, it could float in the air and fly in the air in a way similar to swimming in water, because air was also a kind of fluid. - ** Gliding Principle **: If the dragon's aero shape meets the gliding standard, it can glide in the sky using the air resistance without the need for additional power. It can also fly for a long time with the help of the ascending airflow. - ** Borrowing external forces **: Dragons are often associated with clouds and rain. One can boldly guess whether they use the clouds that are rich in water to fly, just like fish swimming in the water. However, when the clouds rained, there would be huge lightning. It was not very consistent with the characteristics of Earth's creatures that dragons were safe and sound in such an environment. There was also the phenomenon of waterspout, where water spiraled into a pillar and flew into the sky. Dragons might be able to use similar external forces to fly. It should be noted that there was no conclusive scientific basis for the existence of flood dragons. These flight principles were only theoretical speculations based on the characteristics of legendary creatures like dragons. The novel "Flood Dragon" is equally exciting.

The following are some of the main points of autumn photography: ** 1. Grasp the timing of shooting ** 1. ** The principle and influencing factors of leaf color change ** - Autumn in the northern hemisphere usually begins in September and ends in early November. As the temperature dropped and the sunlight shortened, the green chopstick slowly decomposed in the leaves, making other leaf colors visible, such as the orange color produced by the carrots, the yellow color produced by the yellowish, and the red color produced by the cyanidins. - The change in color was affected by altitude and latitude. Trees in the northern regions and mountainous areas (high altitude and high latitude) would change color before trees in the southern regions and closer to the sea level (low altitude and low latitude). - The best viewing period (most of the trees 'leaves have changed color and have not fallen) is very short (3 days to 2 weeks). The exact time depends on the local temperature and the previous weather conditions in the area. It is difficult to predict in advance. However, the period before and after the best viewing period was also a good time for autumn photography. - Each year, factors that affect the brightness and intensity of the colors include the current weather (warm, sunny days followed by cool nights are conducive to brilliant colors, prolonged warm weather softens the colors, and strong winds or early snow cause the leaves to fall prematurely), rainfall in previous seasons (spring and summer droughts delay the color change of autumn leaves), and so on. 2. ** Shooting location selection ** - Different tree species showed different colors in autumn. Common colored trees were cotinus coggygria and red maple. Famous autumn shooting locations in China included Ejina Banner in Inner Mongolia, Jiuzhaigou in Sichuan, etc. However, these places might have a lot of people in autumn, so you could also choose to shoot near your home or in a small area. ** 2. Pre-shooting preparation ** - Before arriving at the filming location, familiarize yourself with the local requirements that may require preparation in advance. Such as understanding the local weather and its changing speed in order to prepare suitable outdoor clothing; Understanding the permission requirements for photography, camping, travel, etc.(may need to be booked in advance); Understanding the animal and plant species that may be threatened in the area, the behavior of local wild animals and plants (migration, mating, hibernation, etc.); Knowing how to be safe and respect other people who like outdoor activities, and when parks, trails, roads, etc. will be closed. ** 3. Cameras Setting and Shooting Techniques ** 1. ** Selection of camera and accessories ** - The right camera is important, and an important camera accessory for autumn leaf photography is a circular crystallizer. When used properly, it can enhance color and reduce glare. 2. ** Camera-Setting Techniques ** - ** Depth-of-field control ** - The bokeh effect can be achieved by minimising the depth of field (focusing some objects and blurring the rest). If you use manual settings, it's easier to achieve. Choose the leaves you want to shoot, use the far end of the zoom lens to shoot, set the camera to aperture priority mode and use the largest aperture (such as f/2.8 or higher, the lower the aperture value, the larger the aperture, the narrower the depth of field, and the better the bokeh effect). - ** Backstory processing ** - You can use a simple background to highlight the shape and color of the leaves, approach the leaves from different angles, look for a background such as a wall that really highlights the leaves, and use light and dark contrast to enhance the quality of the photo. - ** Shooting angle changes ** - When it is difficult to take a satisfactory photo in a fixed shooting area, you can change the shooting angle, such as raising the camera above your head or placing it on the ground. - ** Shooting of a specific scene ** - ** Portrait Shooting **: When shooting with autumn leaves as the background, pay attention to the place where the face is illuminated. Choose a beautiful leaf as a prop. - ** Foreground utilization **: Using autumn leaves as the foreground can increase the beauty of the picture. For example, picking up fallen leaves and scattering them in front of the camera, throwing them a few times, taking many shots, and post-processing can make them even. Autumn leaves could also be used as the background when taking photos of urban architecture. - ** Autumn leaves and flowing water combination **: When shooting flowing water in autumn, falling leaves are one of the best combinations. Using a telephoto to shoot flowing water from a distance can harvest good photos. Slow shutter speed often works well. When composing a picture, considering the background (such as choosing a good stone) is very important to express the texture of the water. - ** Starlight Shooting **: In the morning or evening, when the sun shines through the forest, use a small aperture to shoot the starlight of the sun. Pay attention to the relationship between the starlight effect and the leaves in the lens (the number of starlight rays in the image is related to the number of leaves in the lens. The leaves are odd, and different leaves have different starlight rays). - ** Large aperture shooting **: The long focal length and large aperture can highlight the quiet beauty of a leaf. When the environment is chaotic, you can use water to shoot dreamy colors. Close-ups of beautiful leaves are also very good. - Reflection Shooting: In a place with water, a low angle can be used to shoot a mirror effect. The colorful water surface has a dreamy effect for autumn colors. The leaves in the water, together with the light and shadow, the transparent water waves, etc., will make the picture very realistic. - ** Small Scenery Shooting **: In autumn, you can shoot small scenes such as flowers, grass, trees, and leaves. Especially when the red leaves form a sharp contrast with the background, you can use the color change to show the beauty of autumn leaves. The effect of a good branch and a unique background is also good. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

There were many important points in athlete photography. In terms of equipment, because the athlete was in a state of motion and the movement trajectory was irregular, the shooting space and distance were changeable. It was necessary to use a telephoto lens (such as a 100 - 400mm zoom lens) to close the shooting distance. Because the telephoto lens was heavy, a tripod stabilized camera was also needed. In addition, the camera had to have a high-speed shutter, high-speed continuous shooting function (10 - 20 shots per second was preferred), and a high-speed read-write memory card to ensure the continuity of shooting. There were two types of shooting styles, and one needed to have strong prediction skills when shooting. One was to shoot the frozen moment of the athlete and increase the shutter speed to 1/800 - 1/2000 seconds while maintaining the normal exposure effect. The other was to shoot the dynamic visual impact effect, which required the shutter speed to be slowed down to 1/100 seconds and the camera to be shaken. Pay attention to the speed of the camera to keep consistent with the athlete's movement speed. The purpose of sports photography was to use beautiful composition and light to record the exciting moments of athletes in the game, showing their posture, and having fun and enjoyment. Whenever possible, the shutter speed should be set at 1/500 second or faster; use high sensitivity to ensure enough light, but too high sensitivity will make the photo noisy and unclear; try to show the ball when shooting ball movements; try to show the movement to be big and make the athlete stand out; shoot close to yourself. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
