The slow-motion camera mainly relied on the principle of high-frame-rate shooting. Normal video frames were usually 24 or 30 frames per second, but slow motion photography required a higher frame rate, such as 120 frames per second. When played at 30 frames per second, the picture would be slowed down by four times. In terms of equipment selection: - ** Cameras **: Many modern cameras and smart phones have high frame rate shooting functions. Some professional cameras can reach 1000 frames per second, and some high-end smart phones support 240 frames per second slow motion mode. When choosing a camera, besides considering the frame rate, one also had to consider the sensor size and image quality. - ** Lenses **: The choice of lens is also very important. The wide-angle lens can capture a wider scene, and the telephoto lens is suitable for shooting distant details. For slow-motion photography, it is recommended to use a large aperture lens to ensure that there is enough light for high-frame rate shooting, and to use a stabiliser or tripod to reduce the shaking and ensure the clarity of the picture. - ** Lighting **: Slow motion photography often requires more light because high frame rate photography reduces the exposure time of each frame. For indoor shooting, you can consider using professional lighting equipment or natural light sources. The high-speed camera could shoot high-speed moving objects (such as shells) with the help of a mirror. For example, when shooting the trajectory of the shell, a deflective reflective mirror could be used to reflect the movement of the shell into the high-speed camera lens. The camera remained still, and the rotation speed of the mirror could be obtained by calculating the flight speed of the shell, the angle of intersection, and the distance between the mirror and the shell. If the motion trajectory of the captured object is constantly shifting (such as playing table tennis), two mirrors can be used to do two-axis movement (X-axis and Y-axis). First, the horizontal image captured by the X-axis is reflected to the Y-axis, and then the Y-axis reflects the horizontal and vertical images to the camera to keep the image in the middle. Early tracking used non-optical motion capture (based on measuring inertia and mechanical motion), while modern optical motion capture tracked movement through software. AI artificial intelligence could identify object characteristics and simulate motion trajectories with computer controlled mirrors to better record high-speed moving objects. In addition, there were also some special camera equipment, such as the Pikfang Pet Short videos Self-made Machine, which had an automatic shooting function. Although it was not a specialized slow-motion camera, it also reflected the development and innovation of the camera equipment. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

There were many practical techniques and precautions for slow-motion shots in travel photography. First of all, he had to understand the impact of equipment on the lens. For example, long shots were more obvious than wide shots. This knowledge would help him better use slow-motion shooting. Don't overdo it when using slow motion. Use it only when it adds color to the story and highlights a moment. Take the Huawei P30 Pro as an example. Open the [camera], swipe to the right at the bottom to [more], click [slow motion], put the subject into the square box that appears, and press the screen to lock the focus and exposure to avoid blurring and under-exposure. The default slow motion was 32 times 960 frames per second, which could slow down the normal video by 40 times and show more details. He clicked on the [red dot] to start recording. The system would automatically take a picture when there was a moving object in the frame. In terms of lens operation, such as wide-angle slow-motion card Hongya Cave, you can use the wide-angle rear camera, backhand lens operation technique, combined with 3:4 editing and "Night Flame" filter to obtain a good filming effect. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The company had a variety of cameras suitable for slow-motion shooting. For example, the "FX3" and "A7C" series from Sony supported 4K 60fps video recording, and some models even supported 120fps HD shooting, which could be used to shoot high-quality slow-motion videos. When shooting videos, the SonyA9 had a high-definition mode of 120 frames per second. The Sony-ZV- E10 micro-camera could shoot 1080p/120 frames of slow-motion video. The ILME-FX30 professional film camera had a 4K high-definition back-illuminated 14+ speed super slow-motion shooting function. In addition, the A7S series could also shoot 1080p or 4K video at high frame rates for slow-motion photography. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
