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>

How to use the camera correctly
The correct use of the camera can be started from the following aspects: ** 1. Add a camera (for adding a camera to a video recorder NVR)** 1. ** Private protocol added ** - For video recorder NVR such as Haikang and Dahua, if you want to add a camera of the same brand, you can go through a private agreement. Search the IP channel management interface of the video recorder NVR and check the protocol (for example, the Haikang protocol displayed on the Haikang device). If the password of the activated device is consistent, click the + sign to add it. If the password of the activated device is inconsistent, click the custom add in the lower right corner and manually enter the password. 2. ** Add Onvif protocol for camera ** - If you want to add a third-party camera that supports the onvif protocol, you need to first enable the onvif protocol in the camera. In the IP channel interface of the video recorder NVR, click custom add, manually fill in the IP address of the camera, select the ONVII protocol, the port is the port number of the camera manufacturer, and the password is the camera password. Then click OK to add. 3. ** Added the camera with the GB28181 protocol ** - When the recorder NVR supports the GB28181 service, the added camera also supports this function. First, set up the GB28181 parameters in the camera configuration (when the video recorder is used as a server to add a camera, the port of the SIP server is 5070), select "Add manually" in the IP channel management, enter the IP address information of the camera, select the national standard for the manufacturer, enter the username and password, and click OK to add. 4. ** Added in a custom way (using the streaming method of the Real-Time Streaming Server)** - The camera to be added must support the streaming function. For example, Haikang Equipment can click "custom add" in the IP channel configuration, select "protocol management", and enter the stream address of the main and sub-streams of the camera's IPs in the "resource path" column (main stream: /ch1/main/av-stream, sub-stream:/ch1/sub/av-stream, the format of the stream address is: [type]://[IP address]:[port]/[resource path], such as: rtsp://192.168.0.1: 554/ch1/main/av-stream. Different brands have different stream access paths, so you need to consult the manufacturer). 5. ** Mass import and add cameras ** - It is used when there is a need to add a batch of PC cameras in the monitoring project. First, add a camera to the network, then choose to export the unencrypted. dsv file. After opening and editing the IP address of other cameras with excel, import the video recorder NVR. ** 2. Basic operations during filming ** 1. ** Mobile mode ** - It is best to hold the camera firmly with two hands, or use the supporting objects or stand beside you to reduce the shaking of the picture as much as possible. You should avoid shooting while walking, except in special circumstances. 2. ** Using the camera ** - Focus on shooting with a fixed lens. After setting the image size, turn on the camera and record. Don't do any zooming in or zooming out or sweeping up, down, left, right. By adjusting the size, angle, and position of the camera (such as the side, high, low, etc.) to enrich the image, avoid standing on a fixed point and using the zoom lens to constantly zoom in and out (unless fixed by a tripod). 3. ** Manual Function Usage ** - ** Manual brightness adjustment function **: When shooting backlights and night scenes, if the shooting effect of the automatic mode is not good (when the backlights are used, the main body or characters are all black and the background is bright, and the lights are blurry at night), you can press the backlights correction function button. If not, you can switch to the manual mode to adjust the brightness (brighten the backlights and dim the night scenes). The brightness can be adjusted according to the image or display data on the viewer or the LCD screen. - ** Manual focal length adjustment function **: In special circumstances, such as being separated by barbed wire, glass, or people moving between the target and the autofocus image, which causes the focal length of the autofocus image to be unstable, the autofocus will be switched to manual mode, and the focal length will be locked at a fixed position.(The display and adjustment methods of each brand are different. Please refer to the instruction manual.) ** 3. Equipment Connection and Testing ** 1. ** Equipment connection and line connection confirmation ** - When the camera was installed and debugged, the first thing to do was to wire it, prepare the auxiliary materials according to the equipment specifications, and wire it according to the actual scene. Then, he connected the devices and connected the front-end and back-end devices according to the basic topography. There were two ways to confirm the line connection. One was to start the command in the lower left corner of the window menu bar of the computer and find the IP of the front-end camera through the ping command (this method was time-consuming and needed to be checked all the way). The second was to use Dahua Tool Manager to quickly find all the devices connected online and modify the device IP. 2. ** Function Testing ** - You can enter the camera's WEB side from Dahua Tools Manager and Quick configuration tools to set the password and perform function tuning. ** 4. Special operations and precautions ** 1. ** About Fully Automatic Pet Cameras (Take Pikfang Pet AI Cameras as an example)** - If it is a fully automatic pet camera, you may need to download a mobile phone APP and connect to the Internet when you use it. You can control its forward turn, camera rotation, etc. on the app. You can also use its two-way voice, laser to tease pets, and pay attention to its automatic recharge distance and other features. 2. ** Other Points to Take Note of ** - If the device's LCD monitor can be rotated, pay attention to the rotation limit (for example, the maximum rotation can be 180 degrees to the lens and 90 degrees to the user). Do not use too much force during operation. When the ZOOM key on the left side of the camera is moved to the left, the zoom ring can be used manually. When moving it to the right, it cannot be used, otherwise it may damage the camera. When pulling out the microphone, press the Push key and pull it out.

If you use a tripod, pay attention to its height and position adjustment. For example, when shooting a fishing float, the tripod could be lowered and moved forward to keep the camera parallel to the fishing rod, and the position could be adjusted to make the float in the video image suitable. For example, the float could be enlarged to be in the middle of the video. - Place the equipment according to the lighting situation, such as choosing a position that is suitable for the light, so that it is convenient to take a clear drift. 2. ** Operation during shooting ** - Zooming was crucial. After the rod was thrown into the water, the image could be adjusted by the zoom lever. For example, push the zoom lever to the right twice to see the floating phase, and push the zoom lever in the opposite direction to shoot the scene of the fish. - During the shooting process, the shooting rhythm should be adjusted according to the situation of the fish mouth. For example, when the fish mouth is dense, the shooting should be stopped. - There were corresponding operations for special situations. For example, in the case of water, the operation method of the zoom lever needed to be adjusted, such as pushing the zoom lever fully and slowly releasing it to obtain the largest scene. 3. ** Post-processing ** - Post-processing may be needed after the filming is completed, such as editing a long shot into a video of suitable length, such as editing a two-hour video into a five-to-six-minute video. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
