Why do you use white balance in the studio with a DSLR?
In the studio, there may be other factors such as environmental light reflection that interfere with the camera's ability to obtain standard colors. Usually, manual white balance adjustment is used to achieve satisfactory colors. In the studio, 18° neutral gray cards or white balance cards were often used to adjust the white balance, which was a custom white balance. Read more exciting novels for free
Use a DSLR for TikTok
There were the following points to using a DSLR to shoot TikTok: 1. ** Device selection **: You can choose a Short videos camera prepared for the blogger that costs 4000 - 5000 yuan. It has 2K -8K resolution and comes with beauty and anti-shake functions. If you wanted better image quality, such as a bright night scene and blurred background, you might need a large aperture lens or a telephoto lens (priced in tens of thousands). 2. ** Stabilizing auxiliary equipment **: You can use a tripod and a Bluetooth remote control to stabilize the camera, making it easy to pan the lens and zoom in and out. It can also be equipped with a stabiliser, such as Zhiyun's WBBS3Lab, Djiang's Ruying, Demon Claw's Aircross2, etc. The choice of stabiliser depends on the size of the camera (micro-single or single-lens reflex) and load requirements. 3. ** Picture frame and picture quality **: Most of them use a DSLR + Stabilizer to shoot vertically at a 9:16 frame. They can shoot 1080p or 4K videos. The picture quality is usually much better than that of a mobile phone, and they can shoot special lens effects. 4. ** Choice of lens **: For example, when shooting a video of a beautiful woman on the street, you can use a Canon DSLR with an anti-shake lens such as the ES70 - 200IS to shoot with your hand. You can shoot with the prominent character and the blurred background. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
DSLR photography is white
DSLR photography may be caused by the following reasons: 1. ** Over-exposure **: Over-exposure will cause things to lose a lot of details and become layered, causing the image to turn white. 2. ** Flash is too strong **: If you use a DSLR flash to shoot, the flash will be too strong, and the photo may appear white. 3. ** White balance setting problem **: The camera is not that smart. Different light may affect its judgment of white. For example, under dim indoor light or incandescent light, it may cause deviation in white and become white. 4. ** Inappropriate shooting mode **: If you use the scene shooting mode, but the actual shooting scene does not match the selected mode, it is easy to cause color reproduction problems, which may lead to white. 5. ** Mishandling color settings **: DSLR cameras are highly controllable. Mishandling color settings may cause unnecessary problems, including the image turning white. 6. ** Monitor effect **: If the shooting scene is bright and observed through the monitor, there may be problems with inaccurate exposure and color reproduction, which may cause the picture to turn white. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
How to use a DSLR to blur the background
The following methods could be used to blur the background: 1. ** Aperture size adjustment **: Use aperture priority mode (A). The larger the aperture (the smaller the aperture value), the smaller the depth of field, and the higher the degree of background blurring. The smaller the aperture (the larger the aperture value), the greater the depth of field, and the lower the degree of background blurring. 2. ** Adjusting shooting distance **: When shooting, move the lens close to the subject to make the distance between the lens and the subject close. After focusing, the background will appear blurred. The closer the shooting distance, the smaller the depth of field and the higher the degree of background blurring; the further the shooting distance, the greater the depth of field and the clearer the background. 3. ** Focus adjustment **: When the distance between the person and the subject is fixed, the background will be blurred by adjusting the focus to zoom in on the subject. The longer the focal length, the smaller the depth of field, and the higher the degree of background blurring; the shorter the focal length, the greater the depth of field, and the higher the clarity of the background. 4. ** Using the above methods at the same time **: By adjusting the aperture, focal length, and shooting distance at the same time, you can get a more obvious depth of field effect, but at least one of the two needs to be met: a large aperture or a long focal length. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
White balance of scanner
When performing the white balance of the scanner, the first thing to do was to clean the scanning glass inside the scanner main body, the tabletop of the scanner main body (the manuscript delivery tabletop), and confirm that there was no dust or garbage on the paper used for the white balance. It will take some time to perform the calibration. During this time, do not turn off the scanner's power, or there may be a problem that requires after-sales service personnel to solve. The paper used for the measurement should be properly kept to prevent it from being damaged, distorted or dirty. The measurement paper is a paper product and cannot be cleaned with liquid. The specific steps were as follows: 1. Start (scanner adjustment), display (scanner) menu, select (white balance adjustment). 2. After the relevant screen was displayed, he chose (All) and clicked (Execute). 3. Follow the instructions and insert the paper into the scanner. 4. Press (OK) to start the calibration.10 minutes later, the calibration. Press (OK) to end the calibration.1 5. To confirm the result of the adjustment, you can click (Confirm) on the (White Balance Alignment) in the (scanner) menu and insert the adjustment paper into the scanner again according to the prompt. 6. The scanner began to scan after clicking (OK). After the scan, check the read data to confirm that there are no vertical stripes such as white stripes. If there are no abnormalities in the data, the adjustment operation will end. Then, click (Close) to exit (the scanner adjustment program). If there are abnormalities in the data, select the specified part from the (white balance adjustment) menu, move the mouse to the cross on the data, and point to the striped part to specify. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
How to use a DSLR to shoot background blurring
In order to take a picture with blurred background (depth of field), the DSLR lens had to meet at least one of the conditions of a large aperture or a long focal length. Major manufacturers had some specialized portrait lenses, such as fixed-focus lenses (portrait lenses) with a focal length of 85mm and an aperture of F1.8 or larger. There were also large-aperture zoom lenses with a focal length of 24 - 70mm or 70 - 200mm that were also suitable for portraits. It should be noted that in actual shooting, the larger the aperture, the better, because the image quality will be better when the lens aperture is contracted. For example, an 85mm, F1.8 aperture lens has better image quality when the aperture is F2.8 than F1.8. The image is sharper and the resolution is higher. In addition, the focal length of the DSLR lens was 18 - 55mm (or 18 - 70mm), and the aperture was only F3.5 - F5.6. Using such a lens to shoot portraits, the effect of background blurring was very limited. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
White balance inconsistent with the environment
White balance was a setting used to ensure that white objects appeared white during shooting. Under normal circumstances, white balance should be adjusted according to the surrounding light to restore color. However, if the white balance setting was not consistent with the environment, it would produce a special effect. For example, if the white balance is set to a higher color temperature (such as a high color temperature value corresponding to more blue light) in an environment with a lower color temperature (red and yellow light), the overall image will be colder, which is inconsistent with the actual warm color environment. On the contrary, if the white balance is set to a lower color temperature in an environment with a high color temperature (blue light), the image will be warmer. This white balance setting that was inconsistent with the environment could be used in creative photography to create a unique atmosphere, express specific emotions, or achieve artistic visual effects by deliberately breaking the conventional white balance setting. In some scenes that needed to highlight subjective emotions or special visual effects, the photographer would adjust the white balance according to his own creative needs, so that it did not match the actual color temperature of the environment, rather than simply pursuing the accurate restoration of the color of the environment. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Color white balance algorithm
The white balance algorithm was to find the neutral color points of different brightness in the image (these points should theoretically satisfy R = G = B, but they may not be equal due to color cast), and then map them into equal values to obtain the action matrix of balanced color, and then carry out color balance processing on the whole image. Calculating the brightness of the original image with color deviation, the point close to the maximum brightness value is defined as a white point, calculating the average value of the R, G, and B color components and the brightness average value of all the white point set, and then calculating the adjustment parameters of color balancing according to a specific formula. Finally, the color balance adjustment is carried out on the R, G, and B color components of the entire image. There was also a multi-mode white balance algorithm that was based on the traditional white balance algorithm in the field of cameras. It added an AI white balance algorithm and an auxiliary color temperature sensor to integrate a variety of information to achieve a better white balance effect. This algorithm could accurately identify the true color temperature of the current light in the green or blue screen background scene, thus perfectly restoring the true color of the host and the product. It could achieve the true and natural color restoration of objects in all color temperature environments, and the skin color effect of people was excellent. Increases the authenticity and stability of the white balance, the ability to express colors, and the ability to restore the atmosphere. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
White balance Detection Tools
The following are some white balance Detection Tools: - In PS, you could enter the Camera Raw through the filter " Camera Raw " filter. The white balance tool in the basic panel could be used to correct the color bias of the photo. The white balance tool was a slanted straw icon that could absorb the reference object in the picture. The ACR would automatically determine and adjust the white balance parameters. - The gray card in the Anwenk Gray Card Set was a basic white balancing tool. The set also included pure white and real black cards. - VidPro WD- 24 white balance disc, with an 18% gray exposure target on one side and a white surface on the back. It was foldable and could be placed in a suitcase when not in use. - ExpoDisc 2.0 white balance filter was the industry standard for white balance filter. It could capture the incoming light reading and set a custom white balance accordingly. It was available in 77mm and 82mm thread size. - Some cameras had a white balance evaluation function, such as a LCD camera, which could detect the appropriate white balance setting by placing your finger in the center of the screen and constantly changing the camera's white balance according to the environment. - In the premiere, if there was a white object in the photo, you could use the " straw " tool behind the white balance to click on the white object for automatic white balance correction. You could also manually adjust the color temperature and color, but you needed color knowledge. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
White balance algorithm classification
White balance algorithms were commonly categorized into Gray World Assimilation, Perfect Reflection Assimilation, and dynamic threshold method. Among them, the average, perfect reflection, gray world, color correction, dynamic threshold, and so on can also be used as different white balance algorithm strategy modes. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
How to use the studio camera
Here are some ways to use the studio camera: 1. ** Mode selection ** - Manual mode: This is the most commonly used mode for studio shooting. The photographer needs to manually adjust the exposure, shutter speed, and so on to better control the exposure and shooting effect. - ** Semi-automatic mode **: For example, aperture priority mode and shutter priority mode, some parameters are automatically adjusted. For example, when shooting a portrait, the aperture priority mode could be used to adjust the depth of field. - ** Fully Automatic Mode **: All parameters are automatically adjusted by the camera, suitable for quick shooting or snapping. 2. ** Adjusting exposure **: Choose the appropriate exposure parameters according to the different subjects and scenes to make the subject brighter and clearer. 3. ** Choice of lens **: The fixed-focus lens can obtain better image quality and a wider angle of view. The zoom lens can adjust the shooting distance and angle more flexibly. You can choose the appropriate lens according to your needs. 4. ** Use flash **: By adjusting the brightness and color of the light, you can achieve different shooting effects. 5. ** Adjusting shooting angle **: Shooting from different angles and heights can make the subject more three-dimensional and vivid. Trying different angles can help you find the best shooting angle. 6. Pay attention to the composition: Use the rule of thirds and the golden ratio to make the picture more balanced and harmonious. 7. ** Shooting in RAW format **: It can record more details and color information, so that it is easy to adjust the exposure, color, contrast, and other parameters to obtain the best shooting effect. In addition, when shooting in the studio, especially when taking photos of products, the landline stand in the studio was the key equipment. In actual shooting, when using a heavier flash head and larger accessories, you can also use a large stand. At the same time, the studio cameras could also be adjusted according to the photographer's preferences. Generally, one camera had to be hung on the roof of the studio, and the rest could be freely arranged. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
