Have you ever tried to take blue or yellow photos? Want to shoot a blue snow scene, but it's all white and yellow? Want to shoot golden dusk, but not as golden as you think? Many people will worry about whether there is a problem with the lens or the fuselage! In fact, all this is related to the white balance setting of the camera. White balance sounds professional. But when you understand the principle of white balance, it will make it easier for you to get the ideal color tone and feeling in shooting! Adjust the white balance to get "more accurate" colors. Different light sources have different "color temperatures", which leads to different tones in the whole photo. The so-called color temperature, we will use cold and warm to describe. Simple example: white tube lamp is a kind of light source with high color temperature, and its color tone will be cold/blue; On the contrary, the color temperature of tungsten lamp is low, and the color tone will be warmer/yellower. In fact, the color temperature is the surface temperature measured by comparing the light source with an absolute black body (a substance that will absorb all light theoretically but will not reflect or be penetrated by light), and the measurement unit is Kelvin (K) degrees. The lower the color temperature value, the more inclined to red, and the higher the value, the more inclined to blue. The following is the color temperature table: The following are some common color temperature examples: 1600K: sunrise and sunset 1800K: candlelight 2800K: tungsten lamp/light bulb (daily household light bulb) 3200K: fluorescent lamp 5000K: daylight, which is the most commonly used standard for professional light boxes for photography, art and other purposes: brilliant noon. Electronic flash 6000K: It's cloudy 6500K: It's cloudy 8000K: It's foggy 16000-20000K: The color temperature of the weather photography course with blue sky is warmer: for example, if you want to present a warmer, warmer, nostalgic and hometown flavor, you can use warmer color temperature (fine K value). Cold color temperature: For example, if you want to present a cold, high-tech and near-future feeling, you can use cold color temperature (high K value). Under normal circumstances, our naked eyes will not find these "color temperatures", because our naked eyes know how to adjust them automatically, so if the color temperature is not too outrageous, otherwise a blank sheet of paper will always be blank in our eyes. However, our camera is not as good as our eyes. Many times we need to guide our camera and tell us the color temperature at the scene. White balance is to tell the camera what white is. How to guide? It's simple. If we shoot indoors and the light source is tungsten lamp (2800K), we will "heat" the camera a little and adjust it to the so-called normal neutral color temperature of about 5000K, and we will get the most reasonable color tone, and vice versa. Generally speaking, there are three methods for digital cameras to obtain correct white balance, namely automatic/semi-automatic and manual operation. Automatic white balance mode: automatic white balance mode-the camera estimates the color temperature of the scene by itself and automatically makes the most appropriate adjustment. You will find that it is roughly accurate most of the time, but it is still possible to make mistakes for too complicated light sources. Semi-automatic white balance mode: tungsten lamp/bulb, usually represented by a bulb. We will choose this mode when shooting indoors, especially when the main light source is tungsten lamp/bulb. The meaning behind this mode is to tell the camera that the current color temperature is about 2800K, and it is necessary to raise the temperature to make the photo have more realistic/ideal colors without being too "cold". Fluorescent lamps are also used for indoor shooting. Compared with tungsten lamp, they have higher color temperature. They also told the camera to raise the temperature a little, which would be smaller than when using tungsten lamp. Sunlight can tell the camera that there is no need to make any adjustment, because the current color temperature is very ideal, 5000-5600 K. It is mostly used outdoors and set in the midday sun. The color of the flash is similar to that of sunlight, but it is a little "colder" than sunlight, and the camera will be a little "warmer". Cloudy days are set in cloudy weather, and the color temperature is "cold", so the camera will make a relatively large "warm" action. When the subject is in the shadow position in the shadow sunlight, we can generally use this setting, which is colder than the color temperature on cloudy days. Manual/custom white balance mode: With the development of modern technology, using automatic or semi-automatic white balance mode can make you get the ideal color in most cases. High-end digital consumer cameras and DSLR will be equipped with manual white balance settings. There are two modes of custom white balance: one is to take a piece of pure white paper (ordinary white paper is only nearly pure white, so you can find a photographic equipment called "white card" on the market), use the "custom white balance" of the camera, and then press the shutter on the white paper. The significance of this is to tell the camera what is "white" under this light source. Two: Another way to customize the white balance is to directly assign the color temperature (K number) to the camera. After accurately telling the camera the color temperature, the camera can accurately calculate what is white and the corresponding other colors. In fact, white balance means that different light sources have their relative color temperatures, so it is necessary to tell the camera exactly what the color temperature of the light source is when shooting, so that the camera can make an accurate interpretation of the color. In order to take good photos, we must not be sloppy in the white balance. Some photographers deliberately use a white balance that doesn't match the ambient light to get a special tone, thus highlighting some themes. You can also try boldly in this direction. For example, if the white balance of the camera is set to be k higher than the color temperature of the ambient light source, a warmer/red tone can be obtained; Conversely, if the white balance is set to k number lower than the color temperature of the ambient light source, a cool/blue tone will be obtained. For example, under the scorching sun at noon, set the white balance in the "shadow" mode, and you will shoot warmer/redder tones; On the contrary, under the scorching sun at noon, set it as tungsten lamp, and you will get a cool/blue tone. As shown above, the shooting location is indoor, and the light source is a universal electro-optical gun. The white balance on the left is set to tungsten lamp, and the camera can react by increasing the color temperature, so that the white cup is still white. The white balance on the right is set to sunshine, which makes the white cup yellow. From the results, the white cup on the right turned yellow, and the white balance was obviously "wrong". I still like this yellow tone photo, which gives off a comfortable atmosphere. Therefore, as long as you understand the principle of white balance and its application skills, you will be more handy when shooting life photos or creating special photos.
