Okay, fellow photographers, here's a question for you. Those Goth models, we love 'em, but a lot of them have pale, pale skin and dark hair. Even with the best of depilation regimes, often you have what appears to be stubble problems, or at least visible dark spots under that pale skin. What's to be done?
What I personally do is use the healing brush and/or clone stamp to get the worst of it - definitely any actual protruding hair, and the biggest and/or darkest bumps. Then, I use an applied Blur via the Snapshots technique, usually set for something like 30% opaque, 30% flow, 50% hardness. This works fairly well and doesn't take long. If I had an image I wanted both perfect and extremely light and creamy - that "marble statue" look that drives all the boys wild - I'd probably use the airbrush to go over with a very, very pale white at 5-10% opacity and 30% flow.
If'n anybody has a better way, I'd love love love to hear it!
Here's a little retouching tip that's handy with models with pale skin (although breakouts happen to us all, they tend to be most common with younger models.) If they have areas of skin with a reddish cast (like around blemishes, or where they've been wearing something tight or lying on something,) you can use the Channels palette to help remedy the situation.
Switch to Channels, and hide all but the Red channel (click the eyeballs next to Blue and Green and they'll go away.) Now, grab the Dodge tool. Set it to Midtones and start at, say 10% exposure. (The proper settings will vary according to the model's individual skin situation.) Set to a relatively large (ideally you want to cover the whole area with one pass to avoid overlapping strokes) and fairly soft (well under 50%) brush. Dodge the area in question: it should get lighter. (When you're only looking at one color channel, the image appears in grayscale, which makes it easy to see the relative change you have made.)
Now switch back to RGB by clicking the eyeball (actually, the empty box where an eyeball should be) next to the RGB line at the top of the Channels palette. The area should be notably less red. By using the Dodge tool instead of the Eraser tool on the Red channel, you'll just *shift* the red values, so you won't change the overall color tone of the area too much. If it's still too reddish, switch back to the Red channel and take another pass. If it was too much (the opposite of Red is Cyan: overdoing this technique will make the skin look, well, cyanotic) then hit undo, lower the exposure on the Dodge tool, and try again.
Have fun!
