What is the relationship between color temperature and white balance?
I don't know if you realize that if you just compress photos and upload them to your blog later, most of them will look "not so good". The most important thing is that the colors are unreal and a little gray. So everyone will post-process the uploaded photos, of course, color processing often becomes a bright spot. But once the color is over-processed, you will think it is "fake"-unreal. This problem is really a headache, but often those photos that you think are "fake" are actually "beautiful". Especially those photos that love creative photography, such as composite photos, which you have never seen in real life, are called "beauty". In fact, the core of the above topic is a problem of color reproduction. The key to color reproduction of digital cameras is to find out what the white balance is in digital cameras. Below, I made two schematic diagrams, one is the corresponding table of color temperature and white balance settings of digital cameras, and the other is the schematic diagram of the relationship between color temperature and white balance. In fact, these two schematic diagrams are completely the same thing. The first half of the schematic diagram of the relationship between color temperature and white balance shows the change of color temperature from morning to noon to dusk. The lower part shows the color effect when setting the white balance of the digital camera. Setting the white balance of a digital camera is really a troublesome thing, and the corresponding color effect on the schematic diagram above will be very different from the actual shooting effect. To this end. It is an indisputable fact that most photographers basically do not use the manual white balance function of the camera, but are used to the automatic white balance function, because the automatic white balance function of digital cameras can cope with almost all shooting situations. It is precisely because people are used to using automatic white balance that the photos we take are basically "gray". Therefore, the post-processing of digital photography has a broad space and market, and a large number of post-processing software came into being. In fact, the post-processing of digital photography has become an indispensable means of digital photography, which may be a kind of "soft joy" compared with traditional film photography. The two sketches provided today may have been taken by friends in their spare time. At the same time, I would like to remind you that we have mentioned it many times in the past-the topic of "under comparison" in digital photography exposure, which is in the case of strong light. Under normal light, as long as you set the manual white balance at the right position on the basis of ensuring normal exposure, the color effect of the photos will definitely be greatly improved, especially those "gray" photos will not appear.
