Begin retouching the second of four images in Photoshop. Apply a first past process with skin cleanup. Use patching and liquify to create a solid base for skin and volume to the subject, before moving into a multi-layered approach
In a second pass, approach skin cleanup with a targeted perspective, isolating specific areas to dodge and burn. Develop a more dimensional, even look, focusing on specific areas to protect and repair.
With the major areas of cleanup resolved, learn to apply a procedural and methodical approach to skin smoothing. Create even texture with tone.
