Create a new layer (Cmd/Ctrl+Shift+N) and name this layer Dodge and Burn. Go to Edit>Fill and full this layer with 50% grey, set the blend mode to Soft Light with 50% Opacity. Now you can paint on this layer with a black or white brush to enhance the highlights or shadows.
Go to Layer>Create Clipping Mask then create a new layer and name this layer Noise. Go to Edit>Fill and fill this layer with 50% grey, set the blend mode to Soft Light. Go to Filter>Noise>Add Noise and add 3% of Noise. Clip this layer in the same way as before.
