How does ps set off the dark style?

Copy a layer of photos first, and the mode is frontal superposition. Then, select the curve in the newly created layer and adjust the contrast according to the color in the picture to be toned. After adjustment, use CTRL+ALT+E to stamp the layer, and then use CTRL+J to copy another layer. Add a mask to the newly created layer. Masks use gradient tools to draw gradient effects from top to bottom. Then select "Front Overlay" as the layer overlay mode. Then stamp the picture, create a new color balance adjustment layer, adjust the color and reduce the distortion. Create a new layer if you want to create a particularly non-mainstream dark tone effect. Then select the point gradient in the gradient, and the color selection is as shown in the figure, from white to black. Then select Reverse. Superimpose the top selection mode positive film and adjust the opacity to achieve the final effect.
