This classic tone is used for making landscapes images appear three dimensional and to evoke timelessness.
1 Starting point
Pick an image that would benefit from the toning process—one that has a rich tonal range, including whites and blacks, plus some textured elements too.
Start by selecting Enhance > Adjust Color > Hue Saturation. In the bottom-right corner, as shown above, select Colorize. Drag the Hue slider to 40 and reduce Saturation to 25–30. This will create a rich sepia color.
3 Adjust the contrast
Toning often flattens the contrast a little, so to make it punchy again, open the Levels dialog. Move both highlight and shadow triangles toward the center, as shown above.
