How to restore photos to true color?

Hello, to understand this question, we must first know what is true colors. The so-called true color is not true, because all the colors we see are produced by the reflection of light by objects. Then different lights will produce different colors on the object. For example, under the irradiation of incandescent lamp, we will see that the object is yellow, which means that the object is yellow. We want to shoot the real color of the object, so we need to know the color temperature of the light, and then adjust it to the color temperature of the light on the camera. The shot may be close to the real color, remember that it is only close.

For the camera part, for example, we know that the color temperature of the sunlight at noon is about 5300K-5500K, so we can customize the color temperature of the 5D3 camera, set it to 5500K, and then shoot it to get a picture close to the real color.

There are two points in computer software processing: 1. Take a picture in RAW format, and then do RAW processing on the computer, so that the color temperature of the picture can be easily adjusted.

2. Before taking a picture, put a standard gray board (gray board with reflectivity of 18%) in the middle of the picture and take a picture, and then you don't need this gray board for shooting. Then go back to the computer and use the curve function of PHOTOSHOP software, click the gray straw tool, and then click once on the gray board in the picture. At this time, you will find that the color of the picture is very close to reality. Store this curve and apply it to the pictures taken later.

All personal experiences are by no means copying, and the pursuit of color reproduction is endless, only infinitely close. I hope my answer is helpful to you.
