The final step is to smudge out any harsh edges, mostly at the tips of the hair where it meets the face and shoulders.I like to use a large spatter brush for this, set to about 60% strength, for a wispy look.The final image after smudging:This example took me about 8 minutes to produce, but you can always spend more time tweaking strands and highlights. If you're working on a larger image, it will take longer. Further ways to tweak the hair:- duplicate the hair layer and adjust the hue/saturation, then vary the opacity or blending mode of the adujsted layer. (I usually like to use overlay or one of the light modes.)- duplicate the hair layer and vary the contrast using curves or levels, then vary the opacity or blending mode of the adjusted layer as above.- use the sharpen and blur brushes to vary the focus of highlighted or shaded areas of the hair.
