Digital Portrait Painting from Photographs-Part 2
To help you choose appropriate colors, observation of your fellows, in all kinds of light, is invaluable. Old Master paintings, viewed on-line or in print, is another excellent resource.
Here we added a flesh tone layer over the green shadow at his temple. Soft Light.
This layer colors the eyes. The process is the same as the other color layers.

Switch to the Face Layer, click the Magic Wand Tool outside the head. Delete the surrounding area, working through all the layers. This will clean up any overflow caused by the blurring. Select/Deselect the marquee. Make the background layer invisible. Go Layer/Merge Visible. There is no going back now! SAVE OFTEN!

Activate the background layer Use the Smudge tool and carefully work the dark brown stroke you created on the face layer at the beginning of the project. This will feather it and make it less harsh. Select/Reselect/Delete. Create a new layer, and using the Brush Tool, 3px, and a dark brown color, redraw details that may have been obscured or were missing in the original. Around the eyes, nostrils, crows feet, moles, freckles and character lines around the mouth. Perform the color layer ritual, blurring slightly, just enough to blend the edges into the surrounding base colors.

We are now going to work on the hair. Use the Lasso Tool to trace around the hair. Filter/Sharpen. Do this repeatedly until you are happy with the result. Create a new color layer in the color you want the hair to be. In our case we opted for #AA7A48, a medium brown. Go to Select/Reselect to activate the Marquee. Select/Expand 3px. Gaussian Blur.

Play with the settings in the Blending Mode pallet. The red-head at left was with the blending mode set to overlay
This is Soft Light...

This is Color Burn, Opacity 40%. In other words...season to taste. This is the setting we chose

Create a new layer, and use the Brush Tool to paint a hi-light color over the lightest parts of the hair and beard. Slather on the color!

Gaussian Blur and change the Blending Mode to Soft Light. This will make the hi-lights in the hair and beard POP.

Where the ear meets the head and the part in the hair are too light. We created a new color layer,#D6B283.

We performed the usual ritual, changed the Blending Mode to Multiply.

Deactivate the background layer, Merge Visible. Reactivate the background, SAVE. Finished! Time, Patience and experimentation were all it took to reach this result! All that's left is to put the head in an appropriate setting. Hope you had fun. Regards, BoltCutterDesign.
