This tutorial introduces a more artistic blue-gray effect. When making it, first adjust the overall contrast and tone of the photo, then stamp the next layer, invert it, and then change the layer blending mode. This way, the original image can be restored to a great extent. The color difference in the photo is reduced, and the overall feeling becomes more integrated!
