The 15 Minute Makeover: Photoshop Beauty Retouching
2 The 15 Minute Makeover: Photoshop Beauty Retouchin
Stage 3: Use the Red Channel From the Merged Layer to Smooth the Skin
Now that the Background and all the major retouches have been merged into a single new layer, we get to the fun part! To get started we need to copy the Red channel of the merged layer and paste it into the file as a layer at the top of our layer stack.
To do this, make just the Red Channel in the Channels panel active by clicking on it. Then hit Cmd/Ctrl+C to copy the channel to the clipboard. Next, click on the RGB composite channel and hit Cmd/Ctrl+V to paste the channel as a new layer. With this task accomplished you can now delete the merged layer (named Layer 1 by default) residing just beneath it. Look at the image below for an alternate way to accomplish this task.
Regardless of how you end up with a (monochrome) 'Red channel' layer at the top of your stack, the magic begins when we change the Blending Mode of this layer to Luminosity. Suddenly everything looks lighter and more radiant – and the skin looks amazing.
|Radiant Skin: Here we see the result of the Red Channel of the merged layer, with the Blending Mode set to Luminosity.|
Some Finishing Touches
The effect shown above works great for skin. If you look carefully, however, you can see that our subject's eyes, hair, and lips do not respond so well to this kind of enhancement. That's often the case, and this effect doesn't work very well on clothing either, for that matter. No problem. Our next step is to mask this layer so the change is applied only to areas of bare skin.
|Almost there: The retouched image with and without Red-Channel-Luminosity-Blend-Mode-Smoothing.|
A great way to do this is to first select the skin by going to Select>Color Range. With this tool you can quickly select the skin tones, while leaving hair, eyes and lips unselected.
With our selection still active, we add the layer mask by going to Layer>Add Layer Mask>Reveal All. The mask will automatically appear in the shape of the selected areas. Refine the mask as needed, using brushes and, if necessary the (awesome) Refine Mask Edge feature in the Masks Panel.
In the example below, you can see a progression of the steps we've just undertaken. Once we fixed the most obvious flaws via our retouching layer, we used a copy of the Red channel to make the skin smoother and then applied a layer mask (as well as a duplicate) to restrict the smoothing to skin areas.
|From Left to Right: A) Retouched Image with no smoothing. B) Red channel smoothing visible everywhere. C) Soft-edged layer mask that restricts smoothing to the skin. D) Image with the layer mask applied.|
Your Layers panel may look a little crowded, but we've really only done about five or six basic edits – et voilà! I think this is a remarkable result for the effort.
|The final image shows just how productive those 15 minutes can be.|
I hope you'll find this method a useful (and fun) addition to your arsenal of Photoshop techniques. Of course you can build on these steps for even more control and flexibility. Sometimes I'll use multiple smoothing layers, all placed in a layer group, with a single layer mask. On some images I'll even add a Curves adjustment layer clipped to the smoothing layer(s) for the best results. And if you're a fan of actions, this entire workflow can easily be recorded and later run automatically and interactively, saving even more time on future projects.
