When we take a picture, in addition to the main body, composition and light screen, we also need to adjust the temperature of the picture, which is the so-called “temperature” of the picture. For the camera, the “temperature” of the picture is represented by white balance, and to adjust the white balance, we need to control the color temperature to achieve. < / P > < p > in general, the lower the color temperature adjustment on the camera, the more blue the color; the higher the color temperature, the more yellow the color. For example, when shooting sunrise and sunset, the light at that time appears yellow. If the photographer wants to restore this color deviation, he needs to try to lower the color temperature of the camera. For Nikon cameras, it is recommended that you use the “automatic white balance” option in the camera, which can effectively restore the real color of the scene, so as to complete the creation. < / P > < p > when you are ready to use the warm and cold colors of the screen to take photos with special atmosphere, it may be difficult to achieve the effect you want only by relying on automatic white balance. At this point, we can adjust the white balance of the screen through the two ideas of pre shooting and post decoration. < / P > < p > the previous adjustment requires us to use custom color temperature K value. If you want your own pictures to be warm and warm, you need to increase the K value. This kind of picture “temperature” is often suitable for the shooting of family parent-child, afternoon, sunrise and other subjects, expressing a relatively relaxed and relaxed mood. < / P > < p > if you want the picture to be cold and bring cold color of cold light blue, we need to adjust and reduce the K value. Cold colors can bring a cold feeling. When the temperature is lower than the temperature of the snow, for example, the camera can adjust the color of the snow scene. At the same time, the cold color “temperature” picture can also highlight the melancholy and elegant temperament. In some Japanese tone shooting, the screen will be adjusted to a relatively cold color. The post decoration can be adjusted by the photographer’s personal creation intention. The photographer can choose to record Nef format to obtain higher post space of the picture, and then use Nikon’s software to post process the photo, so as to obtain a photo with a certain “temperature” tendency. With post production, it is particularly important to choose high-quality models such as Nikon z-7. High pixel and high tolerance of the screen can retain more details for us, so that the later more comfortable. American companies begin to give up R & D: who should pay for corporate research?
