Basic knowledge of camera phone
The basics of mobile photography included the following: 1. ** Basic Operation ** - [Familiar with Equipment]: Understand the basic shooting interface, functions, focal length of the lens, and performance under backlighting. There were subtle differences in the performance of different brands of mobile phones. For example, Huawei focused on shooting modes and functions, and slow-door photography performed well; Apple focused on shooting speed and comprehensive imaging; OOppo and Vivo leaned towards portrait photography. - ** Focus and exposure **: Precise focus is the foundation of shooting, which can ensure that the main body of the picture is exposed in place. - ** Shooting Mode **: The phone has a variety of functions, including shooting functions and modes, such as super night view, electronic aperture, portrait mode, streamer shutter, slow door, etc.(Different brands of phones may have different functions). - ** Shooting Techniques **: Commonly used shooting techniques include panoramic mode, macro photography, slow-motion photography, time-lapse photography, slow-motion, etc. You must master panoramic mode operation, panoramic split photo shooting method, macro photography external lens use, etc. 2. ** Scenery, composition and lighting ** - "Shooting and composition: It is important to learn the skills of shooting and composition. For example, the three-point composition method uses the nine-square grid reference line to assist in composition. By placing the subject at the intersection of the four reference lines, you can easily compose the composition. If the picture was messy, the composition could be optimized by changing the focal length and adjusting the shooting angle. For example, switching to 2x focal length, letting the sky and scenery occupy half of the picture, and putting the character on the three-point line; using three times the focal length to increase the shooting angle, the character occupied the middle and lower two squares of the picture, and could also be switched to portrait mode. - ** Light **: The use of light is very important. Try to choose a scene with uniform sunlight for outdoor shooting. When the light is insufficient, you can use some methods to improve it, such as increasing the sensitivity of the camera to the light sensitivity (outdoor to about 100 - 200, indoor to about 400, and night to about 400 - 800). Turn on the flash in the dark environment (can be set to automatic mode). You can also use tools such as shavers and mirrors. Different measuring methods are suitable for different scenes. Matrix measuring is used for broad seascapes, mountain views and other landscape photos; center-focused measuring is used when the main body is in the center of the picture and there is a large difference between the main body and the background; spot measuring is used to highlight small and medium-sized subjects in the picture. When shooting portraits, it is recommended to measure the position of the face. 3. ** Shooting precautions ** - ** Avoiding common problems **: For example, when shooting the event scene, prevent the main character from stealing a glance at the camera and destroying the atmosphere. It is necessary to avoid problems such as blurred, dim, slanted images, cut characters, scattered eyes, distorted images, messy images, and the main character not being prominent. - ** Basic Operation **: Learn how to turn on or off the flash, switch between the front and back cameras, and switch between portrait and scenery modes. On the phone screen, use two fingers to zoom in and out of the subject (zooming in will reduce the quality of the image, so you can change the method to get close to the subject). On the camera interface, click on the screen to drag the focus point up and down. The small sun beside it can quickly adjust the exposure. - ** Picture stability **: When shooting, hold the phone with both hands, stretch your arms out a certain distance to assist, and put your elbows on both sides of your body to hold it. When the subject moves, move the entire body instead of the phone. - ** Sound processing **: If the video requires sound, try to get as close to the speaker as possible when shooting to ensure that the sound is clear and audible in the environment. - ** Horizontal and Portrait **: If you want the video to be viewed on the monitor or TV screen, you can shoot it horizontally. If you want to play the video through other output devices, you can shoot it horizontally. - ** Choice of scene and angle **: You can add or change props in the same scene. Before shooting, you can determine the theme and think about the shooting location. You can avoid monotony by zooming in and out or shooting diagonally. - ** Setting exposure to be able to focus (fixed focus)**: If the phone has a fixed focus function, it is recommended to use it. Locking the auto exposure is better when shooting surround; manual control of focus is suitable for shooting from far to near. - ** Usage of accessories **: If you want to improve the still shooting effect, you can use a smartphone tripod or a stabiliser.

Basic camera knowledge tutorial
The following is a tutorial on basic camera knowledge: * * I. Cameras by category ** 1. * * Mini PC (Fixed lens camera/body lens all-in-one)** - This was a camera with a non-changeable lens. Originally, the term 'ADC' was used to refer to all digital cameras. However, with the mainstream use of cameras with changeable lenses, cameras with non-changeable lenses were more commonly known as mini DCs. 2. * * Interchangeable lens camera (such as DSLR, micro camera, etc.)** - Single-lens reflex camera: It has a complex optical framing system. Its basic structure includes a lens, aperture, shutter, sensor (film or digital sensor), and viewfinder. - * * Micro-camera **: The size is relatively small. It is similar to an DSLR in function, but the structure is simplified. For example, the mirror and other components are removed. * * 2. Basic structure of the camera ** 1. * * Shot ** - The lens could adjust the focal length and field of view of the camera. Different focal lengths were suitable for different shooting scenes. For example, a wide-angle lens (with a short focal length) was suitable for shooting scenery and could obtain a wider picture; a telephoto lens (with a long focal length) was suitable for shooting distant objects or close-ups. 2. * * Aperture ** - Control the amount of light entering the camera. The aperture size is represented by the F value. The smaller the F value, the larger the aperture, the more light entering, and the more obvious the background blurring effect. Conversely, the larger the F value, the smaller the aperture, the less light entering, and the greater the depth of field of the picture (the range where the front and back scenes are clear). 3. * * Shutter ** - It determines how long the light enters the camera. A fast shutter speed could freeze fast-moving objects and avoid blurring; a slow shutter speed could cause moving objects to blur, but in low-light environments, more light could enter the camera. 4. * * Light-sensitive element (film or digital sensor)** - It was a key component of the camera. Film was the light-sensitive material used in traditional cameras, while digital sensors were used in digital cameras to convert light into digital signals. The size of the sensor would affect the image quality. Generally speaking, a larger sensor could obtain better image quality. 5. * * View finder ** - It was used to observe the subject. The optical viewfinder of a single-lens reflex camera allowed the photographer to see the same image as the lens through optical components such as a mirror and a pentaprism. Some digital cameras also had an electronic viewfinder that displayed the image through an electronic display screen. * * 3. Techniques of using the camera ** 1. * * Focus * - Precise focus was the key to taking clear photos. Some cameras may encounter difficulties when focusing. For example, the Fuji XT5 may have problems with focusing and easy to lose focus. Different cameras had different focus modes. The most common ones were autofocus (AFF) and manual focus (MT). Automatic focus was suitable for fast shooting, but it might not be accurate in some complex scenes. Manual focus required more experience, but it could control the focus more accurately. 2. * * Exposed ** - The exposure was determined by the aperture, shutter speed, and sensitivity. If the photo is too bright (overexposed), you can reduce the aperture, increase the shutter speed, or lower the USB. If the photo is too dark (underexposed), you can increase the aperture, decrease the shutter speed, or increase the USB. However, it was important to note that if the IQ was too high, it might cause noise and affect the image quality. 3. * * Shooting Mode ** - Cameras usually had a variety of shooting modes, such as automatic mode, programmed automatic mode (P), aperture priority mode (A or Av), shutter priority mode (S or Tv), and manual mode (M). - Automatic mode is suitable for beginners, and the camera automatically sets all parameters. In program automatic mode, the camera automatically sets the aperture and shutter speed, but other parameters can be adjusted. In aperture priority mode, the user can manually set the aperture size, and the camera automatically adjust the shutter speed. Shutter priority mode is the opposite. The user sets the shutter speed, and the camera automatically adjust the aperture. Manual mode requires the user to set all parameters such as aperture, shutter speed, and so on. It is suitable for experienced photographers. * * 4. Different types of camera features and applicable scenarios ** 1. * * Fuji XT5 ** - [Pros: There are a lot of filter, the photos are very realistic, and the camera looks good.] - Disadvantages: Although the screen can be folded, it cannot be folded into selfie mode. It is difficult to focus and easy to lose focus. It is not suitable for novices. - [Usage: It is suitable for people who know the camera or have a photography partner who knows the industry. It is used to take photos with a strong artistic sense.] 2. * * Canon G7 X3 ** - <Pros: Small and light card machine, suitable for vlogging or taking photos. Simple operation mode, even novices can master it.> - Weakness: Poor endurance. - [Usage: Daily shooting, vlog shooting, especially for beginners who want a lightweight camera.] 3. * * Canon A550 (CCD-camera)** - Pros: As long as the flash is turned on, it looks good no matter how you take it. Canon A series is generally easy to use, and the price is relatively low (for example, starting at 300 yuan). - Disadvantages: Slow response when using flash to shoot too cold or too hot, need to wait for the machine to react (such as waiting for 5 seconds), short battery life (usually 1 - 2 hours). - [Usage: It is suitable for taking photos that require flash effects at suitable temperatures, such as indoor portraits.] 4. * * Fuji F40 (CCD-camera)** - Pros: It's smaller and lighter than the Canon A550. It's more attractive, and it takes photos with a soft filter with warm colors. - Disadvantages: Same as Canon A550, such as slow response, short battery life, etc. - [Usage: It is suitable for taking photos with a warm atmosphere, such as portraits or scenery in a fresh style.] 5. * * Film machine (such as the street sweeper film machine of the same model)** - [Pros: You can experience the unique texture of film photography.] - Disadvantages: Difficult to operate, expensive, disposable film cameras can't be re-shot like ordinary cameras, and the number of shots is limited (like clicking 20 times to use up). - [Usage: suitable for people who are interested in film photography and want to try a unique style of photography.] 6. * * Fuji Mini 7C (Polaroid)** - [Strengths: Great for giving gifts.] - [Disadvantages: Not suitable for many people to use, easy to expose unevenly, and there will be a situation where all the people behind are little black people.] - [Usage: Take a selfie, take a souvenir photo, or give it to a friend as a gift.] * * 5. The factors that affect the results of the camera's photos ** 1. * * Appearance related factors ** - Inconsistent product appearance (size, position, shape, color) will affect the results of the photo. You may need to adjust the camera. 2. * * Foreign Matter ** - When the product judges that there is a foreign object in the content, it will affect the shooting effect. The camera needs to be adjusted. 3. * * Position factor ** - When the product was photographed, the position was inconsistent (tray, clamp, work clothes, camera), which also led to the need to adjust the camera to obtain the desired shooting effect. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Introduction to cell phone camera knowledge
The following is the introduction to mobile phone camera knowledge: ** 1. Basic composition and type of mobile phone camera ** 1. ** Photosensor ** - At present, the core imaging components of mobile digital cameras mainly consisted of charge coupled devices (CCDs) and complementary metal oxide-conductor (CMOCs) devices. Due to its low cost and power consumption, the LCD was widely used in smartphone cameras. The imaging quality of CCDs was good, but the manufacturing process was complicated and the cost was high. On the other hand, the price of the LCD was relatively cheap and it was easy to mass produce. With the development of technology, the imaging quality of the LCD continued to improve, gradually replacing the LCD as the mainstream. - There was also the BSI back-illuminated sensor technology, which separated the electrical components from the light by illuminating the sensor from the back. It optimized the light path and reduced the energy consumption of the incident light. In a low-light environment, the image quality was greatly improved, the noise reduction was effective, and the restoration was more realistic. It also increased the exposure area of the photoelement and reduced the loss of light when it passed through the circuit layer. It increased the sensitivity and light absorption, and the image was more delicate. 2. ** Pixel-related Concepts ** - A digital camera's number of pixel-count includes the effective pixel-count and the maximum pixel-count. The effective picture element is the largest picture element that the digital camera can obtain under the condition that the area of the picture element is unchanged, and the largest picture element is obtained after the calculation of the ** 2. Basic operations and functions of the phone camera ** 1. ** Regarding photo mode ** - Different cell phones had different settings for the professional camera mode. It was usually in the photo section. For example, the Glory phone would open [camera] and click [more]-[pro/PRO] to enter the pro mode. - There were many parameters that could be adjusted in the professional mode: - ** Metering methods **: Matrix Metering, Center Illumination, Spot Metering. Matrix Metering was used to measure the entire picture, suitable for shooting most scenes such as scenery; Central Metering was used to measure the center of the picture, suitable for scenes with a clear subject and in the center of the picture, such as portraits; Spot Metering was used to measure the surrounding of the measuring point, suitable for shooting silhouettes under the setting sun, etc. - ** Iso-sensitivity **: It is used to measure the sensitivity of the lens to light. The lower the value, the better the image quality and the darker the picture; the higher the value, the worse the image quality, the more noise and the brighter the picture. It was necessary to increase the USB port when the lighting conditions were poor. For example, when shooting night scenes, the USB port was recommended to be set between 400 - 800. If you want to shoot night scenes with strong lighting effects (such as traffic and fireworks), you can set it to about 100 and use the phone holder for a long exposure to ensure clear and sharp image quality. - **S (Shutter Speed)**: The shutter speed can control the brightness of the photo. The slower the shutter speed, the brighter the image would be if more light entered the screen; the faster the shutter speed, the darker the image would be if less light entered the screen. The high-speed shutter was suitable for shooting fast-moving objects, such as animals running and moving scenes, while the low-speed shutter was suitable for shooting stars, traffic, light tracks, silk waterfalls, and so on. - ** RV (exposure compensation)**: It was a way to control the light. When the environment was too dark, the value of the electric current would be increased. When the environment was too bright, the value of the electric current would be decreased. It was enough to adjust the display to be clearer. - ** AF-Focus: There are AF-S (Single autofocus, suitable for shooting still objects), AF-C (Continuous autofocus, suitable for shooting moving objects), and TF (Manual focus, self-selected area to focus). Generally, autofocus is more convenient. - ** WD (White Balance)**: Able to control the color and temperature of the picture. The lower the value, the colder the picture, suitable for shooting night scenes, snow scenes, etc.; the higher the value, the warmer the picture, suitable for shooting sunrise, sunset, autumn, etc. 2. ** Basic Operation ** - He had to learn how to turn on or off the flash, switch between the front and back cameras, and switch between portrait and scenery modes. - On the phone screen, two fingers apart could zoom in on the subject, and two fingers together could pull away the subject. However, zooming in on the subject would reduce the quality of the photo. It was generally recommended to get close to the subject. - In the camera interface, he clicked on the screen, then dragged the focus point up and down. The small sun next to it could quickly adjust the exposure. - When taking photos in a dark environment, the flash can be turned on to increase the brightness of the environment. Generally, it is set to automatic mode to obtain suitable light. - In order to prevent the lens from tilting, you can use the reference line to assist in framing, such as the three-point composition method. The four intersections of the nine-square grid reference line are the most attractive parts of the picture. Placing the main body on the intersection can easily compose the picture. - When there was insufficient light, the sensitivity of the camera could be increased. The adjustment of the sensitivity of the camera was different in different environments. The outdoor sensitivity was adjusted to about 100 to 200, the indoor sensitivity was adjusted to about 400, and the night sensitivity was adjusted to about 400 to 800. - There were different methods of measuring light, such as matrix, center-focused, and spot. Matrix was used to take pictures of vast seascapes, mountain views, and other scenery; center-focused was used to take pictures where the subject was in the center of the picture and had a large difference from the background; spot was used to take pictures where there were small subjects that needed to be highlighted, such as flowers, trees, and other scenes. When shooting portraits, it was recommended to measure the position of the person's face. ** 3. Common problems and solutions for cell phone cameras ** 1. ** Picture problem ** - Common problems with the image included blurry, dim, or slanted images, cut text, cut characters, scattered eyes, improper images, messy images, and the main body not being prominent enough. - If the person's face was darker in the big light than in the backlighting, the HPR function could be turned on. If you wanted to take a photo with a clear character and blurred background, you could use the large aperture mode. 2. ** Image Quality ** - The original camera had a better picture quality, and the meaning of the photography APP was more to enrich the shooting methods of the original camera rather than to improve the picture quality. Although many mobile phones boasted high resolution, the hardware of cameras and sensors of different brands did not differ much on flagship phones. - In the case of the same screen size, a high-resolution screen usually obtained better picture quality. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
