Night scene parameters of Dajiang sports camera
Taking the Djiang Action4 sports camera as an example, it was not recommended to shoot at night because it was the weakness of the sports camera. However, some of Djiang's cameras were upgraded to improve their night/dark light shooting capabilities. For example, a camera upgraded its LCD from 1/1.7 inch to 1/1.3 inch for a better night shooting experience. As for the specific parameters of the other models of sports cameras in Djiang, there was no relevant information at present. Read more exciting novels for free
How to set the camera parameters to capture the night scene?
The camera settings for capturing night scenes are as follows: 1. ** Aperture **: - In order to ensure the depth of field (front and back clear), you can choose a small aperture, the recommended aperture number is F8 - F13. If you want to shoot the starlight effect, the smaller the aperture, the better. However, if the aperture is too small, it will affect the quality of the image, and the small aperture is easy to cause the phenomenon of refraction. The best aperture is generally F8 - F11. In some cases, the aperture could even reach F16 or above for the "starlight" effect. If the aperture priority mode was used, it was generally necessary to shoot at F5.6 (the index value was larger and the aperture was smaller) to get a larger depth of field. 2. ** Iso-sensitivity **: - Generally, it was set to the original minimum sensitivity, such as 100 or 200 (the minimum sensitivity of different cameras was different). If the sensitivity was too high, it was easy to produce noise. During long exposure times, to ensure the quality of the shot, try to use a low value of the USB. In theory, the lower the USB setting, the better the quality. It could also be flexibly controlled according to the actual shooting scene. 3. ** Shutter (exposure time): - If you use the A-V aperture priority, the camera will automatically measure the light and calculate a reasonable exposure time. For example, when the shooting time was late, the exposure time might be longer, requiring 20 - 30 seconds; when the sky was dark, it might be 5 - 10 seconds. For the first time or if you don't have enough experience, you can take a few more photos and gradually increase the exposure time until you are satisfied with the results. If you hold the camera, you can first open the aperture to the maximum, then set the shutter to the focal length of a second.(For example, if the current focal length is 30mm, set it to 1/30 seconds), and then control the exposure of the photo through the sensitivity. If you use a tripod, you can first set the sensitivity to 100, then reduce the aperture by a few stops, and then set the shutter to control the exposure of the photo. However, the shutter time may be longer. After pressing the shutter, the camera will go black and it will take a few seconds to finish shooting. During this period, do not touch the camera. When shooting at night on the phone, you can choose the highest exposure of 30 seconds, and the time can be selected according to the traffic or light source effect of the shooting environment. 4. ** Compensation for exposure **: - When the camera's light measurement was not accurate or could not meet the requirements, exposure compensation could be used. If it was dark, exposure compensation could be added, and if it was bright, exposure compensation could be reduced. When shooting a city night scene, due to the large difference in the brightness of the 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. 5. ** Focus setting **: - Because it was a night shot, autofocus might not be able to identify the subject, resulting in a failed focus. Therefore, it was recommended to use manual focus. For close-up shots, you could use a strong flashlight to illuminate the subject's focus and then press the camera autofocus button. 6. ** Other settings **: - Prepare a tripod, fix the camera on the tripod, and then turn off the VR setting of the camera (turn it OFF), that is, turn off the anti-shake function. There is no need to turn on the anti-shake function when there is a tripod. If you used the B-door long exposure to shoot night scenes (long exposure usually refers to an exposure time of more than 1 second, generally used for night shooting, light trace photography, water scenery photography, etc.), the camera required the function of the B-door, and must bring a tripod and shutter release to support the camera. For equipment, he could also prepare black cardboard, batteries with sufficient power, flashlights, etc. For portraits, he needed a camera top flash. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Dajiang lens parameters
The following are some of the Djiang lens parameters: - **DJI PL PZ 17 - 28mm T3.0 ASHH lens **: - The lens frame was full frame (36* 24mm). The lens was used as a movie lens. The lens type was zoom. The lens structure was 11 sets of 13 pieces. The lens mount was a PL mount. The filter size was 67mm. - In terms of optical parameters, the maximum aperture was T3.0, the minimum aperture was T22, the focal length range was 17 - 28mm, the closest focusing distance at the 17mm end was 0.19m, and the closest focusing distance at the 28mm end was 0.26m. - The diameter of the lens was 78mm, the length of the lens was 117.2 mm, the weight of the lens was about 520g, the working temperature was-10 ° C to 55 ° C, the storage temperature was 10 ° C to 35 ° C, and the storage humidity was 45% to 75%. - **DJI TL 75mm F1.8 lens **: It is suitable for the 75mm medium telephoto focal length of Zenith X9 - Air lens.

It weighs only 269 grams. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Shooting outdoor sports camera parameters
Here are some suggestions for setting the parameters of outdoor sports cameras: ##1. When there is sufficient light (during the day) 1. ** Exposing **: You can choose the Auto mode, so that the camera can automatically adjust the exposure value according to the light. 2. ** Shutter **: Speed range: 1/100 - 1/8000. The choice of shutter speed depended on the speed of movement. If it was a fast-moving object, a higher shutter speed was needed to freeze the moment; if the movement speed was slow, a relatively lower shutter speed could be chosen to ensure enough light. 3. ** RV (exposure compensation)**: Set it to +0.0EV. However, if the screen is too bright or too dark, you can adjust this value appropriately. A positive value will brighten the screen, and a negative value will darken the screen. 4. ** Iso-level: Choose between 100 - 800. A lower IQ could reduce noise and ensure picture quality, but if there was insufficient light, it might be necessary to increase the IQ. 5. ** White Balance **: Choose AWB (Automatic White Balance) to let the camera automatically adjust the color balance according to the lighting conditions to ensure that the image color is normal. 6. ** Color **: Normal mode can be selected. 7. ** View **: Choose the standard view. 8. ** Image adjustment **: Choose custom, set sharpness to 1, set dryness to 1, and turn off low-light enhancement by default. Choose resolution of 1080p16: 950Fps, and turn on the Super Stabilisation Function. ##2. When there is insufficient light (dusk or cloudy) 1. ** Exposing **: Also select the Auto mode. 2. ** Shutter **: Speed range: 1/50 - 1/8000. The lower limit of the shutter speed was lower than when there was sufficient light. This was because the light was dim and required more time to enter the light. However, one had to be careful to avoid blurring the picture due to the slow shutter speed (for example, blurring caused by hand shaking or object movement). In addition, if the camera supports it, you can set the shooting mode to continuous shooting mode, so that you can take multiple photos with the same action, so that you can choose a satisfactory picture from multiple photos. If you were using the AC3 sports camera from Djiang, you could also set it as follows: slide up from the bottom, choose 1080 resolution, choose 30 frame rate; click on the anti-shake function in the upper right corner, and choose super stability; Go back to the home page, click on the right to set the parameters, choose the exposure to M, set the USB to 100 - 3200, set the shutter to 1/60, set the angle of view to super wide angle, and then turn on the image quality enhancement function. If the picture is too explosive, you can use the ND filter to solve it. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
How to install a memory card in a Dajiang sports camera?
First, the memory card of the D.J. M300 was located at the rear of the plane. There was a rubber cover on the back of the machine that could be opened, and there was a USB port next to it. However, the specific insert method was not found. It was only mentioned that when the memory card of the Dajiang drone camera could not be inserted, it could be inserted backward. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Fuji camera shooting rain scene parameters
When shooting a rain scene with a Fuji camera on a rainy day, the shutter speed must first be considered. If you want to solidify the shape of the rain, you can use a shutter speed of 1/100 seconds or more. However, due to the poor light on rainy days, using a high-speed shutter requires increasing the IQ, which will affect the quality of the image. Therefore, high-speed shutters are rarely used on rainy days. For the Fuji XT4 camera, there was an example of aperture: f/18.0, exposure time: 10/16000, USB: 4000, focal length: 16.0. For the Fuji GFX100S camera, there was an example of aperture: f/2.5, exposure time: 1/50, USB: 1000, focal length: 110.0. However, the parameters of different models of cameras in different scenes needed to be adjusted according to the actual situation. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The parameters of the camera for shooting snow scenes at night
If you were to use a Mi-series phone to shoot a snow scene at night, in the professional mode, the lens selection would be: use ultra-wide angle for large scenes, wide-angle for normal shooting, and telephoto for local macro; focus on the subject and adjust the composition, manually adjust the focus mode until the subject is clear, adjust the "luminosity" to 80, adjust the shutter according to the environment (follow the white plus black minus), and adjust the "white balance" to between 5000 - 6000. If it was any other phone, in the default shooting mode, he could tap on the main body of the snow scene on the screen with his finger, and then a focus frame would appear. At the same time, a small sun logo would appear on the side. At this time, he could directly slide the small sun logo on the side up to increase the exposure brightness. You can also use the professional shooting mode on the phone. According to the results of the automatic dimming, you can manually focus and dim the light again. After locking the focus, you can adjust the exposure parameters or shutter speed in the professional shooting mode of the phone, such as increasing the sensitivity of the camera or slowing down the shutter speed. If there is exposure compensation in the parameters, you can also increase the exposure compensation to increase the brightness of the shot. When using the professional mode of the phone to shoot, the shutter speed S was usually set to 1/50 - 1/200 seconds, and the sensitivity was set to the minimum. If there was an exposure compensation function, the exposure compensation could be increased by 0.3 - 1. However, the specific situation still needed to be flexibly adjusted according to the brightness of the environment. <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>
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>
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>
Night scene parameters of a hand-held DSLR
When shooting night scenes with a hand-held DSLR, the following parameters can be used: 1. ** Light sensitivity (USB)**: Set the sensitivity to auto. If you use a full-frame camera, you can set the sensitivity between 3200 - 6400 in the settings. There is basically no noise within this range. 2. ** Focus mode **: Single-point focus mode is used. The focus point is placed in a bright place. As long as there is light, the camera can focus successfully. 3. ** Shooting Mode **: - Aperture priority mode can be set. The aperture size is determined according to the subject. For example, if you want to blur the background of a person, use a large aperture. If you want to shoot a stationary object at night, use a small aperture (such as F10 or smaller aperture) to ensure the depth of field. - You can also use the shutter priority mode, adjust the shutter speed, and the aperture will be automatically adjusted by the camera. 4. ** exposure compensation **: Check the exposure level on the camera display in real time and adjust the exposure compensation to control the brightness of the image. If the hand shook and the camera was not stable, you could consider using a tripod to assist in shooting; if you were shooting a portrait at night, you needed a low shutter speed (shooting)+ flash (filling light); if you wanted to shoot the night light drag effect, you would use a low shutter speed; if you wanted the starlight effect, you would shrink the aperture + low shutter speed, or add an astral lens. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
