Start by creating a new blank layer above the image or background layer. Next rename the layer Dodge and Burn and change the blend mode of the layer to Soft Light. The lightening and darkening changes will be applied to this layer and the original pixels beneath will not be touched.

To burn in make sure that the new layer is active and then select the default colors for foreground (black) and background (white). Select a soft-edged brush and reduce the opacity to between 20–30%. Start to paint in the bright areas of the image. The black paint combined with the Soft Light blend mode acts like a nondestructive burn in tool.

To lighten or dodge areas switch paint colors so that now the foreground color is white and paint away as before. In this scenario the white paint and the Soft Light blend mode works like a non-destructive version of the Dodge tool.

Start by creating a new layer above the image layer or background layer in your photo. You can do this by selecting Layer > New > Layer or by clicking the Create New Layer button in the Layers palette. Label this layer Texture.

Next fi ll the layer with 50% gray using the Edit > Fill layer command. 50% gray is one of the preset fi ll options available in the Fill dialog. This mid gray fi ll provides a tone for the Add Noise fi lter to work on.

Now change the blend mode of the Texture layer to Vivid Light or Hard Light. Select the Add Noise fi lter from the Filter > Noise menu and adjust the settings in the Filter dialog whilst watching the results preview in the document window.
