Metal products camera parameters
The following are some camera parameters that may be used when shooting metal products: - When shooting metal products with a 24 - 70mm lens, the focal length of the lens was 24 - 70mm, the angle of view was 24 - 70mm, the vertical angle was 53 degrees- 19 degrees 30 minutes, and the diagonal angle was 30 degrees 84 minutes- 34 degrees. - When shooting with a Fujifilm XS10 camera and a Vizos 751.2 lens, the film simulation was set to NPC, the aperture was F2, the shutter speed was 1/200, the Iso200, the white balance was 5200K (0,2), the color effect was strong, the blue was weak, the color +2, the highlights and shadows were-2, the sharpness +1, the noise reduction was-4, the grain effect was off, the dynamic range was automatic, and the exposure compensation was +1. - There was also an example of using the parameters of 100, 10 aperture, and 1/125 second shutter. Later, the multi-sided lasso main object (recommended feathering 2 - 5%), reverse lasso, curve white, and other operations. However, the settings of the camera parameters needed to be adjusted according to the specific shooting environment, the characteristics of the metal products, and the desired shooting effect.

The parameters of the camera
The main parameters of the camera lens were as follows: - Aperture: controls the amount of light that enters the lens. The smaller the aperture, the greater the amount of light that enters the lens, and the more obvious the background blurring effect. For example, in a dark environment, a large aperture could allow more light to enter the camera and take a bright photo. At the same time, it could highlight the subject and blur the background. - ** Focus **: determines the angle of view and magnifying power of the lens. The short focal length lens had a wide angle of view and was suitable for shooting large scenes such as landscapes. The long focal length lens had a narrow angle of view and could zoom in on distant objects. It was often used to shoot portraits, close-ups, or sports events that needed to be zoomed in. - ** Shutter Speed **: The length of time the shutter is opened. A fast shutter speed could freeze instantaneous movements, which was suitable for shooting moving objects, such as fast running athletes. A slow shutter speed could capture the trajectory of the object's movement, such as shooting a smooth effect when shooting water. However, a slow shutter speed needed to be used with a tripod to prevent blurring caused by hand shaking. - [Depth-of-field]: It refers to the range of clear images before and after the focal point. A large aperture would cause the depth of field to become shallow, that is, the clear range before and after the focus was small; a small aperture would cause the depth of field to be large, and the clear range before and after the focus would be wide. - ** Light sensitivity (USB)**: It indicates the sensitivity of the camera to light. The higher the value, the more sensitive the camera was to light. In a dim environment, the camera could increase the brightness by raising the value, but an overly high value would cause noise and affect the image quality. - ** White Balance **: Adjusts the camera to ensure that white objects appear white under different lighting conditions. Automatic white balance (AWB) for daily shooting can basically meet the needs, but it can be manually controlled in special scenes or when you want to change the image effect, such as using the built-in scene mode, manually adjusting the K value, etc. - ** Distortion **: Different types of lenses may have different degrees of distortion. For example, wide-angle lenses may produce barrel distortion, and telephoto lenses may produce pincushion-shaped distortion. This was something to take note of when shooting objects that required strict shapes such as buildings. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The parameters of the camera
There were many parameters for the camera lens. The following were some common parameters: 1. ** Focus **: It determines the degree of zooming of the lens. A longer focal length was used for long-distance shooting. For example, a telephoto lens could be used to shoot long-distance topics such as sports competitions, wild animals, aircraft, etc., and it could also enhance the background blurring effect. A shorter focal length was used for wide-angle shooting, such as wide-angle lenses for landscape photography, architectural photography, and crowded indoor spaces. 2. ** Aperture **: For example, the main camera of the Vivo X200 Pro is equipped with a large aperture of f/1.57, which helps to take brighter and clearer photos in dark environments. Its periscope telephoto lens has an aperture of f/2.67, which can ensure the clarity and details of the picture when shooting telephoto. The size of the aperture affected the amount of light entering, depth of field, and so on. 3. ** Pieces **: It is one of the important indicators to measure the quality of the camera. For example, the main camera of the Vivo X200 Pro is expected to use a 50-million-pel large sensor, and the periscope telephoto lens is equipped with a 200-million-pel periscope telephoto lens. 4. ** Photosensor **: For example, the sensor of the HD - 3000 camera is a LCD; the main camera of the Vivo X200 Pro has a 1/1.28-inch sensor, and the periscope telephoto lens has a 1/1.4-inch base. 5. ** View angle **: For example, the helmet camera lens is a 3.7mm pinhole lens with a 90-degree view angle. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
External parameters of the camera
The external parameters of the camera were parameters in the world coordinate system, mainly referring to the rotation and translation matrix between the camera systems, such as the position and rotation direction of the camera. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Firework parameters of the camera
When shooting fireworks, the camera parameters were set as follows: - * * Shutter Speed (exposure time)**: - If you want to record the fireworks display process, about 3 seconds can perfectly record the temporary fireworks display process; when there are many fireworks in the same place, the best exposure time is within 7 seconds, and the image may be overexposed beyond 7 seconds; if there are more fireworks and the fireworks are concentrated, about 4 seconds is more suitable; if you want to completely record the trajectory of the fireworks from the lift to the release, about 7 seconds is enough. - It could also be controlled within 10 seconds of hearing the "bang" of the fireworks. If you wanted to capture fireworks for a period of time, you could extend the time. You could also control the shutter through the B-door to achieve the required image exposure time. - There were also some parameters for reference, such as shutter speed of 2.80 seconds, 6.30 seconds, 14 seconds, and other parameters for different effects.(Different shutter speeds need to be adjusted with aperture, IQ, and other parameters.) - The shutter speed was 1/20S-1/50S if one wanted to shoot fireworks, and 1/100S or above if one wanted to shoot stars. - * * Aperture **: - When shooting fireworks without blurring the background, the aperture could be controlled in the range of f/8-f/20. There were also examples of aperture settings for different effects such as f11 and f8. When the environment was too dark, the aperture could be set to a larger aperture. When the environment was relatively bright, the aperture could be set to a smaller aperture. If you wanted to shoot fireworks, the aperture was generally between F5-F9. If you wanted to shoot stars, use a small aperture, such as F10 or smaller. - * * USB (Light Speed)**: - The settings were based on the shooting environment. For example, if you wanted to shoot the effect of fireworks, the USB was usually 500. In different environments, the USB needed to be adjusted according to the shutter speed and aperture to achieve the ideal shooting effect. - * * Focus **: There are examples of shooting effects under different focal lengths such as 16mm and 35mm. You can choose according to your actual needs. - * * Focus **: After finding the shooting position and setting up the camera, you must first focus. Since the night sky is almost pure black, there is little information, so you need to pay attention to the focus operation. - * * White balance **: If you adjust the white balance to 2900K (only for reference), you can adjust it according to the actual situation. In addition, for the iPhone, you can turn on the camera in the settings, click to record a video, choose 4K60, turn on HVR, turn off the automatic FPS to lock a frame number, lock the white balance, and click on the main body of the fireworks to lower the brightness to a suitable position when shooting fireworks. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Understanding of camera parameters
The following is an understanding of some common camera parameters: ** 1. Image quality-related parameters ** 1. ** Pieces ** - Pieces were the smallest unit that made up an image. For example, if the long side of a photo was 6000 pixelation and the wide side was 4000 pixelation, the photo would have 24 million pixelation. Usually, the higher the resolution, the clearer the image would be when magnified. However, the quality of the image was not entirely dependent on the resolution, but also on the size of the sensor. For photography, the resolution was an important consideration. Although some people thought that 20 million pixelation was enough, there were advantages to having a higher pixelation. Unless they often shot sports and dark environments, the high sensitivity of high-pixelation machines could not be considered for the time being. This was because some flagship machines sacrificed high pixelation for sports scenes in continuous shooting and high-sensitivity balance. 2. ** size of the sensor ** - There were different types of full-frame and half-frame sensors. The size of the sensor affected the image quality. For example, full-frame sensors might have certain advantages in terms of image quality. 3. ** Picture format ** - The main ones were the RAW format and JPG format. If you don't want to do post-processing, JPG format will do, but if you want post-editing, it's more suitable to choose the RAW format. 4. ** Picture Quality and size ** - For daily shooting, the size can be adjusted to large size and the image quality can be adjusted to high quality. However, when shooting news topics and other situations that required quick release, the photo size might have to be adjusted to M or S. 5. ** Picture Style ** - The camera had a variety of photo styles. It was recommended to choose the "standard" style for daily shooting unless there were special needs or you wanted to try other styles. ** 2. Exposure-related parameters ** 1. ** Aperture ** - The larger the aperture, the brighter the image. The aperture settings were different in different shooting scenes: - The aperture for landscape shots was usually F8 - F11. - When shooting portraits, you can use the maximum aperture or the maximum aperture can be reduced by one stop. - In cultural street photography, if you need to blur the environment, the aperture is F2.8 or larger. If you don't need to blur the environment, it is F8. - The aperture for macro shooting was F8 - F11. - The aperture range for shooting the starlight effect was F8 - F11. - When shooting flowers, birds, and insects, the aperture should be at F5.6 or below, and the best is to have an IQ of 400 or less. - The aperture also affected the depth of field. The larger the aperture, the shorter the depth of field. 2. ** Shutter ** - The slower the shutter, the brighter the image. There were different shutter speeds for different subjects: - The shutter speed needed to be above 1/60s to shoot general body movements. - Walk for more than 1/125s. - Faster than 1/500s. - Running for more than 1/1000s. - Skiing 1/2000s and above. 3. ** Light sensitivity (USB)** - The higher the sensitivity, the brighter the image. For daily shooting, you can set it to "STAR"(automatic sensitivity). When you use manual (M), you may manually adjust the sensitivity to control the image exposure. ** 3. Focus related parameters ** 1. ** Focus point ** - The more focal points a camera of the same brand had, the better. However, different brands had different focusing techniques, and the speed of focusing could not be compared by the number of focal points. 2. ** Face recognition, eye focus ** - It could focus on a person's face, eyes, and even animal eyes. Many new models had this function. ** 4. Other parameters ** 1. ** White Balance ** - Automatic White Balance (AWB) for daily shooting basically meets the requirements. Manual control is required for special scenes or when you want to change the image effect, such as through the built-in scene mode, manual adjustment of K value, etc. 2. ** Metering Mode ** - This included evaluation photography (Nikon Matrix Metering, Sony-called Multiple Metering), spot photography, partial photography, center-emphasized photography, etc. The most commonly used was evaluation photography, but in complex situations, spot photography, center-emphasized photography, etc. might be chosen. 3. ** Anti shake performance ** - The anti-shake function could reduce the probability of taking photos and making it easy to hold the picture when shooting videos. However, the body with anti-shake function was usually more expensive and needed to be chosen between budget and functional requirements. 4. ** Continuous Shooting Speed ** - If you often shoot sports, you need to pay attention to this parameters. Daily applications can basically be ignored. 5. ** Highest and extended IPs ** - If you are often involved in extreme subject matter shooting, you can consider this factor, but you don't have to consider it for daily use. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
English camera parameters
The following are some common English camera parameters and their meanings: 1. ** Metering Mode **: It can be divided into Spot Metering, Matrix Metering, and Center Metering. It is used to adjust the environmental effects and lighting modes according to different environments. 2. ** Iso-Mode **: Iso-level is the sensitivity of the film. The value can be adjusted (automatically or manually according to the environment). The higher the sensitivity, the rougher the film will be. The magnifying effect is average. The light sensitivity will be different at different times (such as early morning, noon, and sunset), so it needs to be adjusted according to the environment. 3. ** Shutter Speed Mode **: S represents Shutter Speed. The shutter speed can be adjusted. The longer the shutter time, the longer the time taken to take a photo. The lower the shutter speed (that is, the longer the shutter is open), the longer the exposure time. It can be used to shoot moving objects. 4. ** SUV Mode **: SUV refers to exposure compensation. When the light is too bright during the day, the photo can be dimmed to prevent excessive exposure from affecting the picture. For every 1.0 increase in the RV exposure value, the light would double. When the photo was too bright, the exposure value would be reduced by 1.0, and the light would be reduced by one. The shutter speed was the exposure time, which was an important factor in the photo. 5. ** AF-mode **: Focus mode, also known as "auto-focus." It was divided into two types, active and passive. The infrared rays sent by the camera tracked objects or people, and the distance of the current object and the subject could be determined. Ordinary mobile phones could achieve these two focus modes. 6. **AWB Mode **: White Balance Mode. Simply put, a piece of white paper will appear in different colors under different light. White Balance will affect the color tone of the entire photo. You can adjust the cool color tone on cloudy days and the warm color tone at sunset. In the parameters related to video shooting: 1. ** RPM (Rate-Picture- Bit)**: Modifies the rate of the captured video. There are two settings, high and low, which determine the clarity of the picture and the file size of the captured video. In monocular camera calibrations, there were: 1. ** Internal Parameters **: 10 camera internal parameters are only related to the camera, including 5 internal matrix parameters K (can be regarded as 4 parameters fx, fy, u0, v0, where fx = f/dx, fy = f/dy, where f is the focal length, dx, dy are the length and width of the point, u0, v0 are the coordinates of the main point in the image coordinate system) and 5 distortion parameters D (k1, k2, k3, p1, p2 are the radius distortion coefficient). 2. ** External parameters **: The relevant parameters from the world coordinate system to the camera coordinate system (used to describe the position of the camera and other information. In the process of camera calibration-related information, the camera's position information and internal parameters are obtained from the spatial points and their corresponding pixel-points). <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The precision parameters of the camera
The camera's precision parameters referred to the size of the actual object in one pel, expressed as (um*um)/pel. The size of a picture element was not equal to the precision. The size of a picture element was fixed during the mechanical construction of the camera, while the precision was related to the field of view of the camera and was variable. The smaller the precision value, the higher the precision. The size corresponding to a single pel = width of field of view/width resolution = height of field of view/height resolution; the pel accuracy = pel size/lens magnification; the pel accuracy = camera field of view/camera resolution; the simple evaluation method of the detection accuracy is: Detection accuracy = the actual size of the X-axis of the image/the number of X-axis pixels. However, the final detection accuracy will be affected by many factors, including the moving speed of the object being measured, light interference, the shape of the object, the contrast of the features, the computing power of the software, and so on. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
What are the camera parameters?
The camera shooting parameters included many aspects: 1. ** Picture format and quality **: - There were two types of photo format: RAW and JPG. If post-processing was not needed, the JPG format was fine, as it took up less memory. If post-editing was needed, the RAW format was more suitable, as it saved more original environmental colors, but most of the photos were gray and took up a lot of memory. 2. White Balance: - Automatic White Balance (AWB) could basically meet the needs of daily shooting and restore the true color of the environment. If you want to adjust the environment, you can also adjust the color temperature parameters later. In addition, the lower the white balance value, the colder the image, suitable for shooting night scenes, snow scenes, etc. The higher the value, the warmer the image, suitable for shooting sunrise, sunset, autumn, etc. 3. ** Light sensitivity (USB): - For daily shooting, the sensitivity could be adjusted to "STAR"(Automatic sensitivity). Now the camera had better high-sensitivity and the image quality was less affected. However, it could also be manually adjusted to 100, unless the three elements of exposure needed to be adjusted to a higher IQ or the quality of the photo was not high. When shooting in low-light areas at night without a flash, it was generally necessary to increase the IQ. 4. ** Compensation for exposure **: - In Aperture priority/Shutter priority mode, the setting of "0EV" was generally sufficient for most scenes. In the automatic mode, aperture priority, and shutter priority modes, the exposure compensation was increased when the photo was dark, and decreased when the photo was bright. 5. ** Shooting Mode **: - There were mainly automatic mode, automatic program mode, P-mode, aperture priority, shutter priority, manual exposure, and other modes. 6. ** Metering **: - Most of the time, you can choose to evaluate the light measurement (matrix light measurement, average light measurement). It can measure the entire shooting scene to meet the needs of most scenes. There were also center-focused average dimming (the dimming area was about 1/3 of the middle of the screen) and spot dimming (about 3% - 5% of the screen) to choose from. 7. Focus: - Commonly used focusing modes were single-point autofocus AF-S (suitable for shooting still objects, etc., half press the shutter to focus once), servo-autofocus AF-C (suitable for capturing moving subjects, half press the shutter to maintain tracking focus), smart autofocus AF-A (automatically select AF-S or AF-C, according to the subject's movement or stillness), and manual focus (manually adjust the focus ring, use when autofocus is not available or when there is an error). 8. ** Picture Style **: - There were many settings such as auto, standard, portrait, and landscape. It was recommended for beginners to choose the standard style first, and then choose or set other styles after familiarizing themselves with photography and camera usage. 9. ** Different shooting scene parameters **: - ** Scene (M-file)**: On a sunny day, around 100, F8, 1/200. On a cloudy day, around 400. - ** Aperture priority mode (LV)**: - Scenery photos taken in the light: F8 - F11, exposure compensation 0. - When shooting a portrait, the maximum aperture or the maximum aperture was reduced by one stop, and the exposure compensation was 0. - Street photography: F2.8 or higher (requires virtual environment)-F8 (does not require virtual environment). - For macro photography, F8 - F11. - [Starlight effects: F8 - F11] - For shooting flowers, birds, and insects, the aperture should be at F5.6 or below, and the best was to have an IQ of 400 or less. - ** Shutter priority mode (TV)**: - General body movements: 1/60s or above. - Walking time: 1/125s or more. - [Fast travel: 1/500s and above.] - Running: 1/1000s or above. - Skiing: 1/2000s and above. - [Bike: 1/2000s and above.] - Normal speed of the car: 1/2000s or above. - [Flight distance: 1/500s] - Follow-up photography: 1/60s- 1/4s - [Freezing birds nearby: 1/4000s] - [Fog Sea: 1/4s or slower] - ** Manual Mode (M)**: - Full Moon: 1/500s, Isotta:200, F5.6 - F8(Clear). - Crescent Moon: 1/500s, USB:200, F4 - F5.6(Clear). - [New Moon: 1/500s, USB:400, F4] - Firework: 1s- 4s, USB:200, F8. - [Lightning: B-door, USB:200, F8 (until the end of the shot, the environment should be darker).] - Street light line: 15s, USB:100, F11 (adjusted according to street brightness). - Water surface boat light line: 30s, USB:100, F8 (adjusted according to environmental brightness). - Galaxy: 30s, USB:1600 - 6400, F2.8 (with super wide angle). - Star Orbit Shooting: Each photo was exposed for 30 seconds, and the next photo was taken at an interval of 1 second. At least 120 photos were taken and stacked later. - Flower Shooting: 1/125s, F2.8, USB:100(sunny weather). - Scenery: 1/125s, F4, USB:100(sunny). - Night scene: 1/15s, F1.8, and 200. - Ripping motion: 1/500s, F2.4, USB:100. - Wedding room: 1/125s, F2.8 - F8, Isotta:400. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Hanging camera parameters
Here are some examples of camera parameters: - In the Nordic-style women's hanging photo example, the camera was Canon 5D4, the lens was 50mm f1.8, the aperture was f13, the shutter was 1/100, the USB was 100, the white balance was 5200K, two MCV DP600WII, one 145*250 flag soft light screen, one radar cover, one camera cable, and one Apple computer. However, it should be noted that the lighting environment and the output of the light will be different, and the parameters will be set differently. The main learning method is the lighting method, and the parameters are only for reference. - In an example of a clothing hanging photo, the camera was a Nikon D300, with an aperture of f/7.1, an exposure time of 10/1000, an USB of 200, a focal length of 22.0, and a lens model of AF-S DV VR Zoom-Nikkor 18 - 55mm. The basic settings of the camera for daily shooting will also have a certain impact on the hanging shot. For example, the photo format can be JPG (when not retouching) or RAW (when retouching), the size can be adjusted to large size, and the image quality can be adjusted to high quality (daily); The white balance can be set to "AWB" for daily use, and can be manually adjusted for special scenes or when you want to change the image effect; The sensitivity can be set to "STAR" for daily use, and it will only be manually adjusted when the manual gear (M) is used. The photo style could be selected as "Standard" in daily life; the most commonly used measurement mode was "Evaluation Metering";; the focus mode could be selected as "AF-S + Single Point autofocus" in daily life; and the exposure compensation was generally set to "0EV" in aperture priority/shutter priority mode. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Large camera parameters
Different types of blockbusters (such as movies, landscape blockbusters, portrait blockbusters, etc.) required different camera parameters. The following are some common settings: - ** Picture format, size, and quality **: If you don't need post-editing, you can choose JPG format; if you want post-editing, the RAW format is more suitable. For daily shooting, the size could be adjusted to large size and the picture quality could be adjusted to high quality. However, for shooting news topics, the photo size might need to be adjusted to M or S. - ** White Balance **: Automatic White Balance (AWB) can basically meet the needs of daily shooting. In special scenes or when you want to change the image effect, you can use the built-in scene mode, manually adjust the K value, etc. - ** Light sensitivity (USB)**: For daily shooting, you can set it to the "STAR"(Automatic Light sensitivity). When you use the manual (M), you can manually adjust the light sensitivity to control the image exposure. - ** Picture Style **: The camera has a variety of photo styles. It is recommended to choose the "standard" style for daily shooting unless you have special needs or want to try other styles. - ** Metering Mode **: The most commonly used is evaluation measurement (Nikon Matrix Metering, Sony-called Multi-Metering), which can satisfy most shooting. In complex situations, spot measurement, center-emphasized measurement, etc. may be selected. - ** Focus Mode **: For daily shooting, choose AF-S + single-point autofocus; for shooting moving objects, choose AF-C + extended focus. - ** exposure compensation **: In aperture priority/shutter priority mode, it is usually set to "0EV", which can satisfy most scenes. At the same time, the exposure compensation must be adjusted according to the "white plus black minus" rule. For the Hong Kong Style night scene blockbuster camera, the settings were as follows: the sensitivity was pulled to above 3200 to obtain a high graininess, the aperture was used to 5.6, and the speed was switched between 80 and 100. If the camera could not adjust the K value, it could directly use the white fluorescent light mode (4000K). Combined with the Canon camera's landscape mode, the sharpness was pulled to the full, the contrast was increased by two gears, the saturation was increased by two gears, and the color tone was pulled to the right to the top. Different blockbuster styles also needed to be adjusted and optimized according to the actual shooting environment and the subject. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
