How to set the camera color space?

Yesterday, an article published by WeChat official account, "Friends who just started the camera: How to set the camera like this", caught the attention of a teacher. He put forward this view in the article:

"The camera initial settings mentioned above, although very important, are not the most important and critical! It doesn't matter if some settings have errors, such as white balance. There is little difference between 320 and 400. You can reset the white balance later. However, some important initial settings of the camera cannot be made up or it is difficult to correct them later. For example, there are two color space settings, one is sRGB, the other is αRGB, SRGB is 8 channels, and the color gamut is narrow, and αRGB is 16 channels, so the color gamut is much wider and the connection between colors is smoother. So what color space should beginners use? If you use S in the later stage of the computer, you can use α in the later stage of the computer, because the S color space has only 8 channels, but the camera will automatically optimize, so the photos taken will be more beautiful, while the α color space has 16 channels, and the color gamut is much wider, but the photos taken are original gray, but it is convenient for later adjustment and production.

Also, the red-eye prevention setting should be turned on!

If the card is not loaded, the release shutter should be closed!

Mirror pre-lifting should also be turned off!

In short, you should read your camera manual, be able to operate each button skillfully and know what each button is for. Don't go online to see the so-called technical skills, that is after you are familiar with your own weapons! ! ! "

My answer is this: discuss with the teacher, it doesn't matter which color space settings you mentioned for beginners, because they are all directly output by jpg, and most of them are viewed on mobile phones or computers, or uploaded to the network. This is all sRGB. Even if they set up Adobe RGB, they will directly convert it into s RGB in the camera. The other thing the teacher said was. Use RAW format when shooting. This format is the raw data recorded in the camera. In fact, his later setting of color space can be changed. This is what I know and understand.

The serious teacher sent such a proof picture.

For photos taken in jpG format, the camera still faithfully records the A color space!

This caused me to think: how to set the camera color space?

The feature of the RAW format is that it only records how much light your lens enters, and there is no change. Your color space setting only records how you set it. When you import the computer, you can reset it at will, not only the color space, but also ISO, white balance, exposure compensation and so on.

This is the advantage of RAW format. I was right. But if you want to change the file, you must use retouching software, not only PS, but also Lightroom, capture one and many other softwares.

The following is the difference after inputting the color space of the camera into the computer.

Strangely, when watching on sRGB monitor, there is no difference between Adobe RGB and sRGB color space saved by camera, but when uploading to web pages and WeChat friends circle, you will find that the photos saved by Adobe RGB are obviously grayed out.

So, thank you very much for your questions and opinions. It also gave me a deeper understanding of color space. The setting of color space is actually a part of photography color management, which involves the setting of shooting, the setting of display when retouching, the setting of color space when exporting settings and the final use direction of photos.
