White balance is an important step of tone parameters in the shooting process.
Adjust the white balance to ensure that the picture is not color cast after shooting.
The specific adjustment steps are as follows:
1, let's find a whiteboard, or a piece of white paper and a white wall.
2. Aim the camera at the white wall and push the focus to a close-up.
3. Press the white button to complete the white adjustment.
What does white balance in photography mean? How to adjust?
White balance is a very important concept of 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 under different light. For example, when the sun rises in the morning, we look at a white object and think it is white. And when we see a white object in the dim light at night, we think it is still white. This is because the human brain has adapted to the color reproduction of objects in different light during its growth after birth. But as a camera, it has no adaptability to human eyes. Under different lighting conditions, due to the imbalance of CCD output, the color of the camera is distorted: the image is either blue or red, as shown in the figure.
? The color of the image in the middle of the picture below returns to 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 use Kelvin temperature to quantitatively represent color. When an object is heated to a certain temperature by an electric lamp or the sun, it will emit 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. Conversely, the lower the color temperature, the more red components, and the image will be reddish. Therefore, if the light that illuminates an object changes, its reflected color will also change, and this change will be reflected in the camera, which will produce different color reduction phenomena under different light. The following table shows the color temperature under some light.
? Color temperature of light source (k)
? Candle 2000
? Tungsten lamp 2500-3200
? Carbon rod lamp 4000-5500
? Fluorescent lamp 4500-6500
? Daylight (average) 5400
? Cloudy sunshine 6500-7000
? Cloudy sunshine 12000- 18000
? As can be seen from the above table, the color temperature under different light is very different, which leads to 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 to compensate different color temperatures, so as to truly restore the color of the subject.
? 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 2500 K and 7000 K. Beyond this range, the camera will not be able to automatically correct the color of the shooting picture, so the manual white balance function should be used to correct the white balance. Please refer to the related articles on using skills for specific operations.

What does the camera color temperature mean? How to adjust the white balance?
Is the scale of the light color of the light source, and the unit is K (Kelvin). The color temperature of the camera is generally between 2800 K and 7700 K. White balance is to adjust the color temperature of the machine to the color temperature of the light source, which is basically the same. Generally, the camera aims at the white paper to adjust the white balance, and the white paper in the display is standard white.
Camera, how to adjust the white balance in two different environments
In the general automatic mode, aiming at the white wall or using A4-sized white camera will complete the white balance adjustment in an adaptive way, which may be long or short due to the different time of the machine.
Manual adjustment: Take Panasonic as an example. First, adjust the machine to manual mode, adjust the balance, face the white wall or use a piece of A4-sized white paper to approach the lens, and the manual balance indicator light stops flashing, and the adjustment is completed.
How to adjust the white balance of Sony camera
There is an automatic locking and holding key next to the battery slot. Turn it to the middle gear, and then press the WHT balance key next to it to select one-button setting, indoor and outdoor white balance.
How to set the white balance of the camera for the party? Is it better to use manual or automatic?
If you shoot a party program with stage lights, use automatic white balance. Manual white balance can never keep up with the strange change of dance lighting. If it is a non-performance party, the hall is a light source with stable color temperature, and manual white balance can be considered.
How to adjust the white balance of Sony PD 150P camera?
1. Set the auto lock to the middle position in shooting or standby mode.
2. Press WHT· BAR.
3. Set the WHT balance switch to A or B.
4. Shoot a white object, such as a piece of white paper that fills the whole screen, under the same light as the object being photographed.
5. Press WHT· BAR.
How to adjust the white balance of surveillance camera
Cameras are usually automatic. The anti-glare camera has buttons that can be adjusted, and the color can be adjusted on the video recorder.
What is the color temperature and white balance of TV camera? how to use
Both have automatic settings to facilitate price comparison. Manual setting is complicated, and it needs some professional knowledge to use it well. However, the photo is so good that you are not familiar with the manual setting. You'd better take one in advance to see if the effect is as you wish.
colour temperature
Application of color temperature in photography;
Generally speaking, there are two types of filters used to balance the color temperature. One is the red 8 1 series filter, and the other is the slightly blue 82 series filter.
Light mirror. The former is used when the light is too blue (that is, when the color temperature is too high); The latter is used to treat red light and improve color temperature. Series 82 filter
Mirrors are not used as much as 8 1 series. In fact, the experience of many photographers is to increase the color temperature as much as possible, not to decrease it. Use a lamp
Shooting the most common sunset phenomenon with a yellow filter will produce an extremely spectacular effect.
How to choose the appropriate color temperature;
The preference of color temperature varies from person to person, which is related to the scenery we see every day. For example, people near the equator see flat land every day.
The average color temperature is 1 1000K(8000K (dusk) ~ 17000 K (noon)), so I prefer high color temperature (it looks more realistic). On the contrary, in
People with higher latitudes (average color temperature is around 6000K) prefer low color temperature (5600K or 6500K), which means that if you use high color temperature,
The color temperature TV shows the scenery of the North Pole, which feels like blue. On the contrary, if you watch subtropical customs on TV with low color temperature, you will feel
I 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 around 8000 K ~
Between 9500K, so TV stations use the color temperature of the audience to take pictures when making programs. But Europe and America are like us because of their usually mild colors.
There is a difference, with the average color temperature of about 6000K throughout the year as the production reference, so when we watch those foreign films, we will find that,
5600 k ~ 6500 k is the most suitable for viewing. Of course, this difference makes us feel the same way when we see computer or TV screens in Europe and America.
The color temperature is red and warm, and some are not suitable.
It is people with black eyes who see 9300K as white, people with blue eyes as blue, and people with blue eyes as white.
We in China look yellow.
To sum up, it is very important to consider, set and adjust the color temperature during shooting. Whether you use a traditional camera or a digital camera.
Machines and cameras. Pay attention to the color temperature!
white balance
The automatic white balance adjustment function is a function that all cameras have now. When the camera faces the object, due to the different color temperatures of the illumination light,
The white balance of the camera is automatically adjusted without manual control. However, when the light in the shooting process exceeds the set range, the work will be automatically white balanced.
If it doesn't work properly, it needs to be adjusted manually.
White ball is a very important link in camera work. Under the indoor tungsten lamp, white objects look like.
It will have an orange tone, and the scenery taken under such lighting conditions will be yellow; But if it's under the blue sky, it's blue.
Tone, under such lighting conditions, the scenery will be blue. In order to minimize the influence of external light on the target color, it is necessary to
This is the so-called white balance adjustment to correct the color of the camera to achieve the correct color balance.
The following lighting conditions need to adjust the white balance:
For example, when shooting candlelight at night or shooting fireworks outdoors; Under some mercury lamps, sodium vapor lamps or other extremely bright lights; Two different colors.
When mixing warm light sources; When shooting with strong backlight, when shooting with macro function; When shooting in the snow; When the ambient brightness is lower than the brightness specified by the camera.
Illumination time; Sunset, sunrise or with a strong red tone, as shown in figure1; The camera and the scene are not under the same light source, so the light ratio is different.
When I was very old. ...
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, a photo taken under the illumination of 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 video cameras default to "white" regardless of ambient light, which means that white can be recognized under colored light and the tones of other colors can be balanced. If the white balance can be adjusted for all this, other colors based on "white" can be correctly restored in the obtained photos.
