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 hue, and the scenery taken under such lighting conditions will be yellowish; 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.
