Portrait recognition camera
The portrait recognition camera was a smart device with many functions and applications. Its functions included, but were not limited to, Face Recognition, human shape detection, intelligent zooming, and so on. For example, some of them were designed with the AWS03A + Sony-based solution, which could provide a variety of functions such as strong light suppression, dynamic white balance, concealment, backlighting compensation, picture adjustment, etc. Some of them could track and recognize faces, automatically adjust the image amplification, and so on. In terms of application scenarios, the scope of application was relatively wide. It can be used for important parts of public activities and gathering places such as parks, factories, supermarkets, community squares, conference centers, stadiums, schools, hospitals, residential areas, commercial streets, large-scale farmers 'markets, etc. It can also be used for indoor and outdoor surveillance videos of hotels, restaurants, entertainment venues, lobby entrances and exits of office buildings, elevators, and other main passages. In addition, the monitoring and identification camera of the sand mining ship in the river uses portrait recognition technology to monitor the sand mining ship on the river to provide data support for the supervision department; the automatic identification warning camera wearing goggles can detect whether the workers wear goggles to ensure the safety of the workplace. There were also some home smart cameras that also had portrait recognition functions. For example, the Xiaomi smart camera C300 dual camera version could achieve AI Face Recognition and other functions. Read more exciting novels for free

Sports portrait camera lens
In sports portrait photography, there were many lenses to choose from. For example, Nikon's AFZoom-Nikkor 80 - 200mm f/2.8D ED lens was used for sports portrait photography. Its large aperture f/2.8 could adapt to different lighting conditions and achieve better background blurring effects. Canon's EF24 - 70mm f/2.8L II USM lens could also be used for this type of photography. It could meet certain shooting needs in terms of focal length. In addition, lenses such as Nikon's AFDK Fisheye - Nikkor 10.5mm f/2.8G ED, AFNikkor 85mm f/1.8D, etc. could also be used for sports portraits. Different lenses had their own characteristics in terms of focal length, aperture, and other parameters. The photographer could choose the appropriate lens according to actual needs. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Portrait camera shooting food
Usually, portrait shots were mainly used to shoot portraits, but they could also be used to shoot food. In terms of focal length, different focal lengths had different performances when shooting food. For example, a wide-angle portrait lens (such as about 16mm-35mm) could be used to show the environment when shooting food, allowing the food and the surrounding environmental elements to enter the lens together, showing the overall dining atmosphere or the scene of food placement. The focal length of about 50mm-85mm could highlight the main body of the food while retaining some of the surrounding environmental elements. It was suitable for shooting food with a certain background. If it was a telephoto portrait lens of 135mm or above, it could better blur the background when shooting food and highlight the details of the food itself, such as the texture and color of the food. However, when using a portrait lens to shoot food, you also need to pay attention to the settings of aperture, exposure time, and so on to ensure that you can take the ideal food photos. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
What is a portrait camera lens?
Portrait photography lenses were used for portrait photography. There were many focal lengths to choose from, and different focal lengths had different characteristics. The wide-angle lens (such as 16mm) has its own characteristics that can highlight the perspective effect of the scene. When shooting close to the subject, it will cause the subject to have an exaggerated distortion effect, which can cause a certain distortion of the portrait to enhance the interest of the picture. The standard lens (such as 50mm) was close to the range of the human eye. The portraits that were shot were intimate. It was more convenient outdoors. Indoors, one could only shoot half of the body. It was relatively easy to get started and was a cost-effective entry-level choice. It could shoot the background blurring effect and could be used to practice composition. It could shoot both half and full-body portraits. Telephoto lenses (such as 85mm, 135mm, 70 - 200mm, etc.) had the effect of compressing the depth of field. They could blur the background and the front to highlight the main body. The smaller the angle of view, the more compact the scene and the overall simplicity. The shooting angle of the 85mm focal length was 28 degrees, which could simplify the background and highlight the character. The background blurring effect was good, and the image quality was good. It was suitable for full-body to close-up shooting from 1.5 meters to 5 meters, which could allow the photographer to maintain a comfortable distance from the model and avoid the sense of oppression. Its perspective angle was small, and the face of the character would look better when shooting close-up. The 135mm focal length could bring a stronger sense of compression and better blurring effect. It could separate the character from the background very well. It was called a small air cutter and was mostly used for close-up shots. In addition, there was also a macro lens that could be used to shoot close-up portraits. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The camera takes a portrait in red
The red color of the portrait taken by the camera may be caused by the following reasons and you can try the corresponding solutions: 1. ** White balance function is inaccurate **: You can adjust the white balance setting of the camera and choose a mode suitable for the environment. 2. ** Effect of environmental color **: If there is only a pure color in the photo, it is easy to cause the white balance to be inaccurate and the photo to be biased. If there is red light in the environment, the picture will also be biased red. 3. ** Inaccurate settings of camera parameters **: The white balance, color temperature, and shooting mode of the camera are not set accurately. It is recommended to completely restore the various parameters of the camera to the factory settings. 4. ** Effect of the camera's built-in special effects **: If you use a certain special effect of the camera, it may cause the photo to turn red. In this case, you need to restore the factory settings. 5. ** Lighting System Problem **: There is a problem with the camera's lighting system, which will cause the image to be distorted. You can only take it for repair. 6. ** The characteristics of the camera itself **: For example, the Fuji camera is sensitive to orange and red objects, and the skin of the person photographed may be red. 7. ** Ways to change your mind **: You can make some adjustments in the later stages of shooting in the RAW format; add one or two exposure levels when shooting portraits; aim at the 18-gray color block surface for measurement; or aim at the bright part of the face for spot measurement, then aim at the eyes for composition; when the person is too far away from the camera, aim at the inner side of your arm for measurement, lock the exposure before shooting; when you customize the white balance, you have to adjust both the color temperature and tone; If the blush was caused by the yellowish light, you could adjust the light source before shooting or use a filter paper to add a blue veil to the lampshade to neutralize the yellow effect. You could also fine-tune the color balance in the post-production software to achieve the desired effect. Try to lower the color temperature setting. Usually, there is a white balance option in the camera menu. You can choose cloudy or cold white to reduce the red warmth on the face (you need to measure the light environment to ensure that the overall light is uniform). <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The background of the camera portrait is blurred
The blurring of the background was related to many factors. First of all, out of focus was the place outside the focal point. The blurred background in a portrait was out of focus. Generally speaking, the more shallow the depth of field (the larger the aperture and the longer the focal length), the blurrier it would be outside the focal length. However, this was also related to the distance between the background and the subject. And different lenses, even if they were of the same focal length and under the same aperture, would have different performances outside of focus. This was related to the quality of the lens itself (including coating, structure, lens itself, etc.), as well as the number and shape of the aperture blades. For example, the shape of the spot outside of focus might be hexagonal, octagonal, or circular. In addition, in portrait photography, medium telephoto lenses (such as 50mm or 85mm) had better performance in moderate background blurring and clear environments, and could effectively avoid the distortion problems caused by wide-angle lenses; Wide-angle lenses (such as 24mm or 35mm) could incorporate more background elements into portraits, making the photos full of story and space, but the photographer needed to pay more attention to the composition and background elements to support the subject. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The background of the portrait in the Huawei camera is not clear
There are many reasons why the background of a portrait on a Huawei camera is unclear. Here are some possible solutions: 1. ** Check shooting mode **: Confirm whether you are using portrait mode or large aperture mode. These modes will deliberately create a blurred background effect. If you don't want this effect, you can switch to other modes, such as normal shooting mode. 2. ** Aperture adjustment **: Drag the slide bar to the left and right of the camera view area to adjust the aperture value. The larger the aperture value, the clearer the background. 3. ** Change the shooting distance **: Reduce the distance between the subject and the background, or increase the distance between the phone and the subject to make the background clearer. 4. ** Avoiding the use of specific functions **: If you use a function that may affect the clarity of the background, such as the "Super macro" mode, you can try to turn off the function and re-shoot. 5. ** Check the camera settings **: Check the camera settings to see if there are any settings related to image quality and resolution that affect the clarity of the background. You can try to adjust it to the default settings or higher settings before shooting again. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Photographer, portrait composition, camera position
In portrait photography, the position of the camera was closely related to the composition of the portrait. The following were some common situations: ** 1. The camera position according to the composition type ** 1. ** Ternary composition ** - The position of the camera could be flexibly adjusted so that the character was located at the intersection of two vertical and two horizontal lines on the screen. Generally, DSLR cameras had three-point auxiliary lines to help determine the position of the character and make the picture harmonious. 2. ** Center composition ** - The position of the camera could be adjusted according to the main body part that you wanted to highlight, but the general idea was to frame the portrait in the middle of the picture. When shooting a portrait, the face facing the side of the picture was a more orthodox composition concept, but you could also face the side of the picture according to creativity. 3. ** Foreground composition ** - The camera's position should ensure that the elements in the background (such as props, flowers, etc.) can be reasonably included in the picture, and at the same time, focus on the character. The distance between the camera and the background and the character can be adjusted appropriately to control the degree of blurring in the background to create a sense of spatial layering. 4. ** Diagonal composition ** - The position of the camera needed to be adjusted according to the layout of the characters on the diagonal line of the screen. The characters could be positioned on the diagonal line by changing the posture of the characters or changing the camera position to bring a visual impact and a sense of spatial extension. 5. ** Framed composition ** - The camera position should consider the relative position of the frame elements (such as door frame, windowsill, man-made flowers and plants, prop frame) and the character, so that the character hides in the frame and forms a surrounding visual effect. 6. ** Triangle composition ** - The position of the camera had to match the pose of the character or combine the scene and props to make the character appear in a triangular layout in the picture, so that the picture was more stable and diverse. 7. ** Symsymmetrical composition ** - The camera should be positioned so that the character is placed in the lower center of the picture. It is suitable for travel photos that combine people and scenery. It can express the relationship between the character and the environment well. ** 2. According to the camera position of the camera ** 1. ** Low position ** - When taking a close-up shot of a model, the camera should be positioned parallel to the model's arm, and the phone should be slightly raised. The photographer could squat down. When taking a panoramic view of the model, the camera was placed parallel to the model's legs and shot from above. A low camera angle could make the legs of the character look slender, which was suitable for girls who wanted the effect of long legs. 2. ** High camera position ** - One way was to shoot from above, and the other was to shoot from a high position (such as a staircase scene). A high camera position could make the object smaller, creating a god's perspective effect. 3. ** Horizontal camera position (flat camera position)** - The phone was placed parallel to the model's shoulder. This was a common camera position for beginners in photography. The image was taken from the angle of a normal human eye. When shooting close-up shots, you can turn on the 2x optical zoom in the portrait mode of the phone. When shooting panoramic shots, you need to pull away the phone without changing the focal power. A horizontal camera could highlight expressions or story-like actions. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
