Step-by-step: Illustrate realistic-looking cobbles quickly
1I create a new layer and paint the cobbled path with a brush I specifically created for this project. To avoid having the cobbles look too similar, I vary the shapes and forms of the stones using the Eraser tool. Then I go to the Edit menu and select the Transform tool. I choose Distort and adjust the layer so it matches the perspective of the image.
2In the Layer palette I reduce the value of the Fill option to zero, which removes the cobbles temporarily. Next, I double- click the layer to access the Layer Styles menu. I select Bevel and Emboss, and the cobblestone reappear with an embossed effect. Among the various options, I choose a direction and colour for the lights and shadows.
3The path is almost finished. Now I add some more details, such as tufts of grass that grow between cobbles, cracks, imperfections and grit. As a finishing touch I select a soft Round brush and choose a light grey. Then I enhance the atmospheric perspective with small brushstrokes, reducing the Opacity to 50 per cent where the path disappears from view.
