How to use photoshop to adjust the photo to cool tone?

1, open the material map, adjust the foreground color in the toolbar to black and the background color to white, then add a gradient map, and adjust the layer transparency to about 50%, as shown below.

2. The adjustment of transparency is mainly based on the needs of pictures. Because each picture is different, no specific data is given here. The adjusted effect is.

The purpose of this step is to reduce warm colors. In fact, this effect is a bit close to the Japanese accent! All right, let's move on to step two.

4. Like the previous map, use the same button to select a solid color, and then fill it with blue. You can't choose too dark blue for the blue here. Just choose a light blue as shown below, and you can add it later if you feel it is not enough.

5. After selecting the blue fill, you will see that the picture is filled with blue.

6. Then select the color deepening as shown above, and the picture is basically completed. Finally, use curves and color levels to adjust the overall picture.
