How to adjust the white balance of camera?

what are the steps to balance the camera?

white balance is an important step of tone parameters during shooting.

white balance is used to ensure that the picture is not color cast after being photographed.

The specific adjustment steps are as follows:

1. Find a whiteboard together, or a piece of white paper and a white wall.

2. aim the camera at the white wall, and push the focal section to a close-up

3. press the white adjustment button to complete the white adjustment.

what does white balance mean? How to adjust?

white balance is an extremely important concept of a camera.

? The so-called white balance is the restoration of white objects by the camera. When we look at the world with naked eyes, we feel the same color in different light. For example, when the sun rises in the morning, we look at a white object and feel that it is white. And when we see a white object in the dim light at night, we feel that it is still white. This is because the human brain has been adapted to the color reproduction of objects under different light during the growth process after birth. However, as a camera, it has no adaptability to human eyes. Under different light conditions, due to the imbalance of CCD output, the camera's color reproduction is distorted: either the image is blue or red, as shown in the figure.

? The color reproduction of the middle image in the picture below is normal, while the image on the left is obviously blue and the image on the right is red, so the images on the left and right are all images with abnormal white balance.

? In order to understand white balance, we must understand another important concept: color temperature. The so-called color temperature, in short, is to quantitatively express color with Kelvin temperature. When an object is heated to a certain temperature by an electric lamp or the sun, it will emit a certain light, which contains not only brightness components, but also color components. The higher the color temperature, the more blue components, and the bluer the image will be. On the contrary, the lower the color temperature, the more red components there are, and the image will be reddish. Therefore, if the light that illuminates the object changes, the color it reflects will also change, and this change will be reflected in the camera, which will produce different phenomena of color reduction under different light. The table below shows the color temperature in some light.

? Color temperature of light source (K)

? Candle 2

? Tungsten lamp 25-32

? Carbon rod lamp 4-55

? Fluorescent lamp 45-65

? Daylight (average) 54

? Sunlight in cloudy weather is 65-7

? Cloudy day sunshine 12-18

? As can be seen from the above table, the color temperature difference under different light is very wide, resulting in different color reproduction of the camera under different light. In order to solve this problem, all current cameras have the function of white balance correction, which compensates for different color temperatures, thus truly restoring the color of the photographed object.

? Now all cameras have the functions of automatic white balance and manual white balance. Automatic white balance enables the camera to automatically correct the white balance within a certain color temperature range, which is between 25 K and 7 K. Beyond this range, the camera will not be able to automatically correct the color of the shot picture, so the manual white balance function should be used to correct the white balance. For specific operation, please refer to the related articles on using skills.

camera mean? How to adjust the white balance?

is the scale of light color of light source, and the unit is K (Kelvin). Generally, the color temperature of the camera is between 28 K and 77 K. White balance means that the color temperature of the machine is basically consistent with the color temperature of the light source. Generally, it means that the camera is aimed at the white paper and the white paper in the monitor is standard white.

How to adjust the white balance of the camera in two different environments

In the general automatic mode, aiming at the white wall or using a piece of A4-sized white paper camera will complete the white balance adjustment in an adaptive way, which may be long or short due to different time of the machine.

Manual adjustment Take Panasonic as an example. First, switch the machine to manual mode, adjust the excellent balance, face the white wall or use a piece of A4-sized white paper to approach the lens, and the manual balance indicator stops flashing, and the adjustment is completed.

how to set the white balance of the camera for a party? Is it better to use manual or automatic?

If you are shooting a party program with stage colored lights, then use automatic white balance. Manual white balance can never keep up with the strange changes in dance lighting. If it is a non-performance party and the hall is a light source with stable color temperature, you can consider manual white balance.

Both of them have automatic setting, which is convenient to compare prices. Manual setting is more complicated, so you need some professional knowledge to use them well. However, if you are not familiar with manual setting, you'd better take a picture in advance to see if the effect is as you wish.

Color temperature

Application of color temperature in photography:

Usually, two types of filters are used to balance color temperature. One is the 81 series filter with red color, and the other is the 82 series filter < P > mirror with slight blue color. The former is used when the light is too blue (that is, when the color temperature is too high); the latter is used to deal with red light to improve the color temperature. 82 series filter < P > mirrors are not used as often as 81 series. In fact, the experience of many photographers is to increase the color temperature as much as possible, rather than decrease it. Shooting the most common sunset phenomenon with a light yellow filter will produce an extremely spectacular effect.

How to choose the right color temperature:

Preference for color temperature depends on people, which is related to the scenery we see every day. For example, people who are close to the equator usually see a flat

average color temperature of 11, K (8, K (at dusk) to 17, K (at noon)), so they prefer a high color temperature (which looks more realistic). People in areas with higher

latitudes (with an average color temperature of about 6K) prefer low color temperature (56K or 65K), that is to say, if you use a TV with a high

color temperature to express the scenery of the Arctic, you will feel blue. On the contrary, if you watch the subtropical customs with a TV with low color temperature, you will feel a little red. How to define the color temperature of TV or display screen? Because the average color temperature of the scenery in China is about 8 K ~ < P > 95 K all the year round, TV stations take photos with the audience's color temperature of 93K in the production of programs. However, because of the differences in color temperature between Europe and America, the average color temperature of all seasons is about 6K K. So when we look at those foreign films, we will find that < P > 56 K ~ 65 K is the most suitable for watching. Of course, this difference makes us feel that when we suddenly see the screens of computers or televisions in Europe and America, we feel that the color temperature is red and warm, and some of them are not suitable.

that is, people with black eyes see 93K as white, but people with blue eyes see 65K as white.

China people see it as yellow.

To sum up, it is very important to consider, set and adjust the color temperature during shooting. Whether you use a traditional camera, a digital camera or a video camera. Must pay attention to color temperature!

White Balance

The automatic white balance adjustment function is a function that all cameras have now. When the camera is facing the subject, the white balance of the camera is automatically adjusted with the different color temperatures of the illumination light

without manual control. However, when the light during shooting is beyond the set range, the automatic white balance function < P > can't work normally, so manual adjustment is needed. < P > White balance adjustment is a very important link in camera work. Under the indoor tungsten light, the white object looks < P > with orange * * * tone, and the scenery photographed under such lighting conditions will be yellowish; But if it is in the blue sky, it will have a blue

tone, and the scenery photographed under such lighting conditions will be blue. In order to minimize the influence of external light on the target color, it is necessary to

ask the camera to correct the color to achieve the correct color balance, which is called white balance adjustment.

The white balance needs to be adjusted under the following lighting conditions:

For example, when shooting candle light at night or shooting fireworks outdoors; Under some mercury lamps, sodium vapor lamps or other extremely bright lighting; When two light sources with different colors < P > are mixed; When shooting with strong backlight and when shooting with macro function; When shooting in the snow; When the ambient brightness is lower than the specified illumination of the camera

; Sunset, sunrise or with a strong red tone, as shown in Figure 1; When the camera and the photographed scene are not under the same light source and the light ratio is quite different < P >. ...

Why do you need to adjust the White Balance when shooting with a camera?

The English name of white balance is white balance. The color of the object will change due to the color of the projected light, and the photos taken under different light conditions will have different color temperatures. For example, photos taken in an environment illuminated by tungsten lamp (light bulb) may be yellow. Generally speaking, CCD can't automatically correct the change of light like human eyes. The following pictures show different images under different colors of light.

Balance means that digital cameras and cameras default to "white" regardless of the ambient light, which means that they can recognize white and balance the tones of other colors under colored light. If we can adjust the white balance for all this, we can correctly restore other colors with "white" as the primary color in the obtained photos.
