Rust Texture with Photoshop

This tutorial describes how to create a rusty metal texture with Photoshop in few steps.

Requirements:
 * Photoshop (I've used CS2 but earlier versions should be ok)

6. Now create a third layer, fill it with the foreground color and again use Filter/Noise/Add Noise with the same settings like before (Distribution: gaussian, Percent: 15% and Monochromatic mode on). Set this layer's Blend Mode to Soft Light.

7. Press SHIFT+CTRL+E to merge the visible layers and then duplicate the resulting layer either by choosing Duplicate Layer from the Layer Menu or by dragging the layer onto the New Layer icon in the Layers Panel.
