Setting parameters of various scenes in the DSLR
The following are the common settings for DSLR in different scenarios: ** 1. Portrait Shooting ** 1. ** Still Portrait ** - [Shooting mode: Aperture priority mode (LV) can be selected.] - Aperture: Generally, a large aperture, such as F2.8 or so, can blur the background and highlight the main character. - Focus: 3 - 4x telephoto is more suitable, avoid using the wide-angle end (may cause the portrait to be deformed), too long telephoto (more than 4x) may flatten the face. - Metering: It's best to choose spot photography. Spot photography on the face and use exposure lock to prevent the color of the clothes from affecting the face exposure. 2. ** When the character moves ** - [Shooting mode: Shutter priority mode (TV)] - Shutter speed: Usually set to around 1/250s to prevent blurring. ** 2. Scenery Shooting ** 1. ** Ordinary scenery ** - [Shooting mode: You can use P or M (manual).] - Aperture: Use a small aperture, such as about F5.6. - [Shot: Use a wide-angle lens to accommodate more scenery and create a sense of distance.] - "Composing: To avoid the center of the scene, you can use the three-point composition, frame composition, symmetrical composition, diagonal composition, white space composition, etc. - Ancestors: It is recommended to bring a tripod to prevent shaking. 2. ** Night scenery ** - [Shooting mode: Aperture priority mode.] - Aperture: F10 or smaller. - Shutter: Normally set to 1/30s. - Light sensitivity: 100. - Metering Mode: Evaluation Metering Mode (Matrix Metering Mode), reduce exposure compensation as appropriate. - [Ancestors: You need a tripod or you can use the shutter release to shoot.] ** 3. Flower Shooting ** - [Shooting mode: Aperture priority mode (LV)] - Aperture: Choose a large aperture lens or a 100-micro lens. A large aperture can highlight the subject, make the depth of field shallow, and make the image soft. - [Composing: You can use the central composition or the nine-square composition to place the main body in the center of the picture.] ** 4. Pet Shooting ** 1. ** Method 1 ** - [Shooting mode: P-grade automatic and continuous shooting.] 2. ** Method 2 ** - [Shooting mode: Shutter priority mode (TV)] - [Shutter Speed: Set to 1/250s or higher.] ** 5. Silhouette Shooting ** - [Shooting Mode: P-file] - Metering: Use spot photography to measure the highlight, then add or remove the exposure according to actual needs, and place the focus on the bright spot. ** 6. Still Life/Food Shooting ** - Shutter speed: 1/80s- 1/200s. - Light sensitivity: 100 - 400. - Aperture: F1.2 - 4. Read more exciting novels for free
Various DSLR photo parameters
The following are the parameters of the DSLR photos in different shooting scenes: ** 1. Portrait Shooting ** 1. ** Aperture **: Use an aperture of f5.6 or larger to blur the background and highlight the main character. 2. ** focal length **: 50mm or above. The shooting distance depends on different requirements such as full-body, half-body, and headshot. 3. Focus: Focus on the person's eyes, making the character look more lively. 4. ** Light sensitivity (USB)**: The daytime USB is 100, and the maximum is 400. ** 2. Scenery Shooting ** 1. ** Shooting Mode **: Aperture priority mode (Av). 2. Aperture: You can use an aperture of f8 or smaller to obtain a larger depth of field and ensure the overall clarity of the picture. ** 3. Shooting of still small things such as flowers, birds, and insects ** 1. ** Shooting Mode **: Av file. 2. ** Aperture **: F5.6 or higher is best. 3. ** Focus **: 50mm or more. 4. ** Shooting Distance **: Try to shoot within 1 meter to blur the background. ** 4. Night Scene Shooting ** 1. ** Shooting Mode **: Av file. 2. ** Aperture **: A small aperture below f8 can create a starlight effect. 3. ** Light sensitivity (USB)**: Within USB 200. 4. ** Shutter Speed **: Slow down the shutter speed and extend the exposure time. This way, the person walking past will disappear from the picture. If you use a hand-held camera, it is recommended to use a tripod or place the camera on a fixed object (such as a stone, stool, etc.) to prevent the image from blurring due to hand shaking. ** 5. Night Portrait Shooting ** 1. ** Shooting Mode **: Av file. 2. ** Aperture **: Around f8. 3. ** Light sensitivity (USB)**: USB 100 - 400. 4. ** White Balance **: Sets automatic or custom white balance. 5. ** Flash **: Use slow sync flash (the camera's default night portrait flash mode). The flash will flash once when the shutter is pressed and once again before the exposure ends. The person cannot leave during the shooting. ** 6. Shooting of moving objects ** 1. ** When the light is good ** - [Shooting Mode: Av] - Aperture: A small aperture below f8 can get a large depth of field, and above f8 can get a shallow depth of field. - Shutter: Continuous shutter option. 2. ** When you want a dynamic effect ** - [Shooting Mode: TV] - Shutter: Set it to about 1/30. When you focus and press the shutter, the lens will follow the target at an appropriate speed to create a dynamic effect. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The role of various parameters of the DSLR
The following are the common parameters of the DSLR and their functions: ** 1. Focus related parameters ** 1. ** AF-ON (autofocus start button)** - It can be set to switch between single focus, autofocus, and servo-autofocus. When taking photos, you can directly use this button to select the focus mode, which is convenient to adjust the focus mode according to different shooting scenes and objects. For example, you can choose single focus when shooting still objects, and you may need to use servo-autofocus when shooting dynamic objects. 2. ** M-GN (multi-function button)** - It can be set to drive mode, focus mode, white balance, light measurement mode, etc. During the shooting process, the button could be clicked to switch the settings at will, allowing the photographer to quickly adjust the shooting parameters to adapt to different shooting needs. 3. ** AF-M (autofocus and manual focus mode)** - Usually, it was set to AF-autofocus mode, and the camera could automatically adjust the focus. However, when the light at night is too dark and the contrast of the snow in winter is low, the camera may not be able to accurately autofocus, or when you need to deliberately use manual focus to shoot a blurry effect (such as shooting at night), you can switch to M manual focus mode. ** 2. Image display and confirmation of relevant parameters ** 1. ** Depth of field button ** - It could be set to a photo style. Through this setting, one could use this button to choose whether to shoot a portrait or a landscape. Different photo styles would affect the color and contrast of the picture. 2. ** Image confirmation ** - After the photo is taken, it will stay on the camera for a certain period of time (can be set, usually 2 seconds) to check the effect of the photo, allowing the photographer to quickly determine whether the photo meets the expectations, such as whether the composition is suitable, whether the desired picture is captured, etc. ** 3. Image quality related parameters ** 1. ** Light sensitivity (USB)** - You can set the minimum and maximum values. During daily shooting, the camera would automatically adjust according to the surrounding light when the sensitivity was set to AUTO. The higher the sensitivity, the more sensitive the camera was to light, but too high a value would increase the noise in the photo. The equipment itself had a maximum value that allowed it to produce the best image. If this value was exceeded, the noise in the photos would increase significantly. 2. ** High Iso noise reduction setting ** - In extremely dark environments, when there is no light, no tripod, and the exposure time cannot be extended, you can set the high Iso-noise reduction to adjust the brightness of the picture. However, this was not an ideal long-term solution. When the environment was not bright enough, it was best to use a light filling device. 3. ** Picture size, format, and quality (such as large size, medium size, small size, JPG, and RAW format)** - Different photo size were suitable for different scenes. For travel photography, large size (L), high quality (Fine) JPG with RAW as the default storage format was better. RAW was used for archive and refinement, and JPG was used for batch processing and fast rendering. For scenes that required a large number of shots, such as news photography, medium size (M) and small size (S) were more useful. Small size could save storage space and shorten transmission time, but after shooting, it had to be adjusted back to large size, otherwise it would affect the quality of the next shot. ** 4. Lens-related parameters ** 1. ** lens aberrations correction (peripheral brightness correction, distortion correction, digital lens optimization)** - Turning on the peripheral light correction could reduce the dark corners of the photos taken, and turning on the distortion correction and digital lens optimization selection standards could improve the image quality and reduce the image distortion caused by the lens. 2. **OS ON/OFF (anti-shake switch, Canon says IS and other brands have different names)** - The anti-shake function was used to compensate for the shaking of the hand-held camera. When the anti-shake function was turned on, the safety shutter could be increased by about 3 stops when shooting with a hand-held camera. For example, when shooting with a 200mm focal length, the anti-shake function could be turned on at a shutter speed of 1/60s to ensure that the photo would not be "blurred." ** 5. Other parameters ** 1. ** Memory card not installed, release shutter ** - If it was set to not close, the shutter could be pressed without a memory card, but if it was set to close, the shutter could not be pressed without a memory card. When shooting important scenes such as events or weddings, be sure to set it to off to avoid mistakes of not installing a memory card to shoot the entire process. 2. ** Gridline Setting ** - When gridlines were turned on (such as 3x3 gridlines), a "jing" line would appear on the camera display, which could be used as a reference line for composition. It would help both novices and veterans in composition. 3. ** White Balance ** - It was important to set a custom white balance in a specific lighting environment (such as when taking a portrait in a room with pink or yellow lights). By setting the pure white photo you just took as the reference white, you can let the camera take photos of natural colors in the same environment. However, every time you set the custom white balance, you have to return to the default value (automatic white balance) after the shooting is completed because this setting is only applicable to the current environment and lighting conditions. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The meaning of various parameters of the DSLR
The following are the meanings of the common parameters of the DSLR: 1. ** AF-ON **: It is related to the focus mode. It can be set to switch between single-shot focus, autofocus, and servo-autofocus. By clicking the AF-ON button, and then clicking the menu button (MENU), you can directly use the AF-ON button to select the focus mode. 2. ** Depth-of-field button **: Can be set to the photo style. In the MENU, press a specific step to find the custom button, and then set the depth of field to the photo style, which can be used to choose whether to shoot portrait or landscape. 3. ** M-GN **: Can be set to drive mode, focus mode, white balance, light measurement mode, etc. Find the custom button in the MENU settings, click M-mn, and select the ticked item in the details. When shooting, click M-mn to switch the settings. 4. ** Image confirmation **: After taking a photo, the photo will stay on the camera for a period of time to check the effect of the photo. You can set the dwell time in the image confirmation option under the menu on the second layer of the first camera setting on the first layer. Generally, you can choose 2 seconds. 5. ** Light sensitivity (Isox)**: The sensitivity of the light sensor to light. The higher the USB, the more sensitive the sensor was to light, and the brighter the image would be if there was more exposure, or the darker the image would be. You can set a minimum and maximum value. The best image that the equipment can bear has a maximum value. If you exceed this value, the noise in the photo will increase. In the MENU setting, the first layer was the left camera setting. He clicked on the 2 option to set the sensitivity of the camera. After entering the sensitivity setting menu, he chose the automatic range and set the maximum and minimum values according to the range that the device could bear. 6. ** lens aberrations correction **: - [** Surrounding Light Rectification **: When turned on, dark corners can be reduced.] - ** Distortion correction **: When turned on, it helps to correct the image distortion. - ** Digital lens optimization **: You can choose the standard. The setting steps were to set the camera settings on the first layer of the MENU. In option 3, click on the lens phase difference correction, set the surrounding light correction to- on, distortion correction- on, digital lens optimization-standard. 7. ** High Iso-noise reduction **: In extremely dark environments, when there is no light or tripod and the exposure time cannot be extended, you can set this function to adjust the brightness of the screen, but it is not a long-term solution. In the MENU settings, the first camera setting on the left, click on the high iso sensitivity noise reduction function in option 4, and you can choose strong. 8. ** Shutter Release Without Memory Card **: If the option is not closed, the shutter can be pressed without a memory card. If the option is closed, the shutter cannot be pressed without a memory card. In the MENU settings, the first layer was the left camera setting. In option 6, click on the uninstalled memory card to release the shutter and choose off. 9. ** Gridline **: It is the reference line for composition. It is recommended to turn it on to facilitate composition. In the MENU setting, the first camera setting on the left of the first layer, click on the shooting information display-show grid line-3x3 grid line in option 7, and a "jing" line will appear on the camera display screen. 10. ** Aperture **: Generally indicated by F, it is mainly used to control the amount of light in the lens. Increasing the aperture by one, the amount of light entering the camera doubled, and vice versa. 11. ** Shutter **: It is used to control the length of exposure time. It is divided into high-speed shutter and slow shutter. The faster the speed, the darker the image. The slower the speed, the brighter the image. 12. ** Depth-of-field **: The distance from clarity to blurriness in the image. It is related to the aperture. The smaller the aperture, the greater the depth-of-field. The larger the aperture, the smaller the depth-of-field. The focal length of the lens also affects the depth-of-field. The longer the focal length of the lens, the smaller the depth-of-field. 13. ** focal length **:(mm) Usually marked in front of the lens, for example: 50mm/24 - 70mm, different focal lengths will affect the image. 14. ** exposure **: refers to the brightness of the photo. You need to adjust the camera parameters such as shutter, aperture, USB, exposure compensation, etc. to control the exposure of the photo. 15. ** RV **: It refers to the exposure index of the camera. The amount of exposure can be achieved through different shutter and aperture combinations. 16. ** Color temperature (K)**: Mainly used to adjust the color of the photo. Generally, the color temperature of natural light is around 4500K. The higher the value, the cooler the photo. 17. ** Automatic Focus Mode **: - ** Single autofocus (AF-S)**: It is used to focus on a stationary object. - ** Continuous autofocus (AF-C)**: Used to continuously focus on moving objects. - ** Automatic Focus (AF-A)**: An autofocus mode. 18. ** Focus area **: The use of the focus point must be used in conjunction with the measuring mode. There are a variety of focus points to choose from. The camera default is the center focus point. The user can choose the appropriate focus point according to the shooting needs. 19. ** Picture Style **: This is equivalent to the default settings for brightness, contrast, saturation, and other parameters. It reduces the number of post-processing steps and is similar to the filter in a mobile phone. 20. ** White Balance (AWB)**: It is the balance of white. It is the default setting for the accuracy of the white color generated after changing the three primary colors of red, green, and blue in the environment. AWB is the default setting of the camera. 21. ** Automatic brightness optimization **: The camera automatically processes photos. 22. **OS ON/OFF (anti-shake switch)**: The anti-shake function can compensate for shaking. Different brands have different names, such as Canon's IS. When shooting with a hand-held camera, the anti-shake function of the safety shutter could be increased by about 3 stops. 23. ** AF-M (autofocus and manual focus)**: Normally, the autofocus mode is set to AF-M. When the camera cannot autofocus accurately (such as when the light is dim at night and the contrast is low in the snow in winter) or when it is necessary to deliberately use manual focus to create a blurry effect (such as shooting at night), the manual focus mode can be switched to M-M. 24. **0.39m/1.3ft (closest focus distance)**: It means that the camera cannot focus when the distance between the camera and the subject is less than this value (39cm or 1.3ft). <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
DSLR party parameters setting
If the party was filmed without a lamp: - ** static characters and scenery (suitable for on-stage speeches, guest check-in, group photos, communication, and other scenes with small movements)**: - [Mode: M mode] - [Shutter: 1/60 second.] - Aperture: F4 - F5.6. - <strong></strong>Because in this scene, the shutter did not need to be too high, and if the light was bright, the USB could be turned on automatically, and the aperture was above F4 to ensure the clarity of the person in the photo. - ** Dynamic Character Scenery (suitable for programs, dances, lottery draws, awards, toasts, and other scenes with strong interaction)**: - [Mode: M mode] - [Shutter: Set to 1/125 - 1/160 seconds. If necessary, it can be increased to 1/200 seconds.] - Aperture: F4 - F5.6. - <strong></strong>Everything was done to capture the main character clearly. As it was a dynamic scene, the shutter speed could not be too slow, and the USB had to be controlled below 3200. In addition, if there was a stage electronic screen in the party scene, since the output frequency of the electronic screen was about 50 Hertz, in order to avoid the appearance of blurred screens and shadows when shooting non-continuous images, you could use a speed of about 1/50 second, speed priority mode, and the sensitivity setting to automatically shoot. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Various parameters of manual mode of DSLR
The main parameters of the manual mode (M) of the DSLR included: 1. Aperture: It was a device in the camera lens that controlled the amount of light that fell on the sensor. It was composed of many small leaves, and its size was usually represented by the F value. The complete aperture value system was F1, F1.4, F2, F2.8, F4, F5.6, F8, F11, F16, F22, F32, F44, F64, etc. Each increase or decrease in the aperture would double or reduce the amount of light entering the lens. 2. ** Shutter Speed **: It is a device that prevents and controls the length of time the light enters the camera lens. It can be manually set in DSLR, mainly including 1, 1/2, 1/4, 1/8, 1/15, 1/30, 1/60, 1/125, 1/250, 1/500, 1/1000, etc. Every time the shutter speed is increased or decreased by one gear, the exposure will be doubled or halved. 3. ** Isox **: It represents the sensitivity of the camera. The higher the Isox value, the more sensitive the camera is to light. However, a high Isox may bring more noise and affect the image quality. 4. ** Focus mode **: Manual focus (MG) can be used. In some cases, such as the contrast of the scene in the picture is small, the contrast is not high, or the focus subject is too close to the background color, manual focus can focus more accurately. 5. ** Metering Method **: There are methods such as center-focused, partial, and evaluation. Metering methods affect the camera's measurement of light, thus affecting the determination of exposure parameters. In addition, different models of DSLR cameras may have other related parameters that can be adjusted in manual mode, such as the drive mode. In manual mode, the photographer needed to adjust these parameters according to the subject matter, lighting conditions, and other factors to achieve the ideal shooting effect. For example, when shooting still life or static scenery, the aperture could be set according to the required depth of field, and then the shutter value could be determined according to the exposure. When shooting high-speed sports, the shutter speed should be determined according to the movement speed, and then the aperture value should be determined according to the exposure. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Nikon DSLR display parameters setting
Different Nikon DSLR models had different display parameters in different shooting modes. Common advanced shooting modes included P (program mode), S (shutter priority mode), A (aperture priority mode), and M (manual mode). In the P-mode (program mode), this was a flexible program mode. Although it was not completely fixed like the automatic mode, it could change the aperture and shutter combination by turning the main command disk. S (Shutter priority mode) was used when the shutter speed needed to be controlled. The main command dial could be turned to change the shutter speed. A (Aperture priority mode) was suitable for controlling the depth of field. Turning the sub-command wheel could change the aperture size. M (Manual mode) was used when the automatic mode could not complete the shooting or when the creative idea could not be achieved. The main command wheel was used to select the shutter speed, and the sub-command wheel was used to select the aperture. However, this was only a general description of the operation of the Nikon DSLR's display parameters in different modes. It also needed to be combined with the performance characteristics of different models. For example, models such as the Nikon D5100 may have more detailed descriptions of the display parameters of the model in their respective user manuals. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Canon DSLR video capture parameters setting
The following are some of the key parameters for Canon's DSLR video capture: 1. ** Recording format **: First, you need to set the recording format of the video. 2. ** Shooting Mode **: Choose the manual mode to shoot. This way, you can easily control the shutter, aperture, sensitivity, and other parameters. 3. ** Shutter Speed **: The slower the shutter speed, the more obvious the motion blur in the picture. Conversely, the picture will be clearer and sharper. 4. ** Aperture **: Aperture mainly controls the brightness of the screen and background blurring. The larger the aperture, the brighter the screen and the stronger the background blurring. Conversely, the smaller the aperture, the darker the screen and the weaker the background blurring. 5. ** resolution, frame rate, and scanning method **: The standard resolution of HD is 1920 x 1080 and 1280 x 720. For network communication, the resolution of 720 is usually clear enough, and it has lower requirements for the capacity of the memory card, storage speed, and post-production computer hardware. However, it is recommended to prepare a larger memory card. There were 60 frames per second (59.94 frames per second), 50 frames per second, 30 frames per second (29.97 frames per second), 25 frames per second, and 24 frames per second (23.98 frames per second). 6. ** White Balance **: If the color temperature of the light source is uniform, the body's automatic white balance can achieve a good performance. If the shooting environment is a mixed color temperature, it can be set according to the built-in mode of the body (such as the sun, cloudy, tungsten lamp, etc.). Some bodies can also be directly adjusted in digital form. The white balance could also be set according to the skin color of the characters in the scene. In addition, the white balance setting was an important method to adjust the color tone of the movie. There was no so-called correct answer, and it required more practice to master. 7. ** For Canon's EOS R5 (part of it involves Canon's DSLR concept)**: You can set one card to a higher-quality 8K 4:2:2 10bit, and the other card to a synchronized recording of 4:2:0 8 bit. This way, you don't need to output a separate agent file. You can directly use the recorded agent file to edit, and the main card file to output the finished product. Moreover, shooting 8K videos could provide more space for post-production. Canon Log could be turned on to obtain a high dynamic range. There were two options in the machine, C. Log3 and C. Log3. C. Log3 had a 12-speed dynamic range, and C. Log3 had a 14-speed dynamic range. It focused on preserving highlight details. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Setting the camera parameters for shooting night scenes
There were many aspects to consider when setting the camera parameters when shooting night scenes: - ** Aperture **: - In order to ensure the depth of field (front and back clear), you can use a medium aperture, such as f/5.6 to f/8. However, there are special circumstances. If you want the camera to get more light, you can use a large aperture (small f-value, such as F1.8), but a large aperture will reduce the depth of field. If you want to ensure the depth of field, you can also use a small aperture (such as f/14). - ** Shutter Speed **: - Usually, a slower shutter speed, such as 1 to 30 seconds, was needed to capture more light. If you hold the camera, you can set the shutter speed to one-tenth of a second (for example, a 30mm focal length, set it to 1/30); if you use a tripod, the shutter speed can be slower. However, a slow shutter speed could cause the picture to be blurry, which could be avoided by using a tripod. - ** Light sensitivity (USB): - You can increase the IQ value appropriately, such as 800 - 3200, but too high an IQ may lead to increased noise, and you need to find a suitable balance. There are also cases where the sensitivity is set between 600 - 1000. If the maximum aperture of the lens is relatively small, you can set the sensitivity to 100 when using a tripod, and then adjust the aperture and shutter to control the exposure. - ** Metering Mode **: - Due to the large difference in the brightness of the night scene, in order to obtain more accurate measurement data, you should usually choose the center-focused or spot measurement mode, and then choose the area that is slightly weaker than the brightest area in the picture for measurement. If necessary, reduce the exposure compensation by 0.3 - 1 to show the deep night. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
DSLR English parameters
The following are some common English parameters for DSLR: 1. ** Metering Mode **: It can be divided into Spot Metering, Matrix Metering, and Center -weighed Metering. 2. ** Iso-Mode **: Iso-is the sensitivity (International Standard Organization). The value can be adjusted. 3. ** Shutter Speed Mode **: S represents Shutter Speed. 4. ** Exposure-Value Mode **: Exposure-Value means exposure compensation. 5. ** AF-mode (auto-focus Mode)**: This is the auto-focus mode, which can be divided into active and passive modes. 6. **AWB Mode **: White Balance Mode. 7. Aperture: The English name is Aperture. The F value is often used to indicate the size and is used to control the amount of light entering. 8. ** NEP (RAW)**: An image format, 12-bit or 14-bit, can be compressed or compressed without loss. 9. **JPEG**: Common image format, fine (approx. 1:4), average (approximate. 1:8), basic (approximate. 1:16) compression. 10. DFC (Design Rule for Camera file system): 11. **Exif (Exchangeable Image File Format for Digital Still Cameras)**: Exchangeable image file format (for digital cameras). <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
DSLR dimming parameters
According to the available information, the dimming parameters of the Silver Swallow SY-28As flash for the Sony-grade single-lens reflex were mentioned. The flash control had two automatic apertures, F2.8 and F5.6, and the flash index was 28 (100, 50mm focal length). However, this was only the dimming parameters of the specific flash. Generally speaking, the dimming of an DSLR camera was related to parameters such as aperture, shutter speed, and sensitivity. The aperture size directly affected the amount of light entering. A large aperture would enter more light, and a small aperture would enter less. A slow shutter speed would allow the light to enter longer, and a fast shutter speed would allow the light to enter shorter. The higher the sensitivity value, the more sensitive the camera was to light. However, high sensitivity might bring about an increase in noise. Under different shooting scenes and needs, these parameters needed to be adjusted to achieve the appropriate dimming effect. For example, when shooting portraits, a larger aperture (such as F1.8 - F5.6) may be used to obtain a shallow depth of field to highlight the main body of the character, but pay attention to the accuracy of the focus to avoid losing details; when shooting scenery, a small aperture (such as F8 - F16) may be used to ensure a larger depth of field to make the whole picture clear. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
