Commonly used color correction methods in photo studios

final renderings
Some of the coloring methods compiled in this series are my own, and some were moved from books to the Internet. I have simplified and adjusted them and will present them to everyone.
1. Open the material picture and press CTRL+ALT+~ to select the highlight of the picture, as shown in Figure 1:
2. Create a new layer, fill it with white, and change the opacity to 50%. The purpose of this is to elevate the image tone of the photo, as shown in Figure 2:
3. Merge the two layers and copy another layer to become layer one.
4. Click to enter the channel panel of layer one, select the blue channel, click Image - Apply Image, and set as shown below:

5. Then click on the green channel and red channel, click Image - Apply Image, pay attention to the opacity of 50% and 20%, do not reverse it, as shown in Figure 3:
6. Duplicate a background layer, drag it to the top, and change the blending mode to Hard Light to achieve a good effect.
Extended effect:
The photos produced by the photo studio will not be so small, so some effects must be done. If the picture is large, we can create a new layer, fill it with 50% gray, and then do Filter - Noise - Add Noise. Note that the data here cannot be large. A little film grain is enough, and changing the blending mode to Soft Light will give you great results.
