Retouching photos to remove skin blemishes and wrinkles is a common task. For faces with only a few wrinkles the Rubber Stamp Cloning Tool works well. But for other images you need another approach.
This technique uses the blur filter.
Open up your image and zoom in so you can see the details you want to remove.
Use the Layers Palette, lower right, to duplicate the layer. I do this by clicking on the Background layer and dragging it over the New Layer icon (like a blank sheet of paper with a curled up corner).
Now with the top layer selected (click on it in the Layers Palette) select the Guassian Blur filter from the Filter menu.
Set a radius of blur that removes all the marks you wish to and maybe a bit more. You can tone it back later, so better to go a bit too far.
Now use the Eraser tool to remove the blurred layer from the areas that you want sharp. Use a large, soft brush and work over the image. Use a smaller brish and pick out the edges of the face, etc.
The Layers Palette has an Opacity slider that allows you to reduce how opaque a layer is so it blends with the one beneath. We will use it here to tone down the effect so that it looks more natural.
And there you go, all done. The secret is to not to try to take off too many years, as the shape of the face changes as well (we’ll see how to do that later).
