The human skin isn’t as smooth and even as it used to be. At least if you are older than 12 or so. One way to keep up the illusion of eternal youth is image manipulation. Today I explore one way to smooth skin and keep it looking natural. That’s the problem with overly done make up and postprocessing – if you overdo it, faces look like made out of plastic. There is a difference in size between “good” and “bad” skin structures. The Wavelet Decompose plugin can divide an image into “scales” and a “residual”. Each scale contains a …



The human skin isn’t as smooth and even as it used to be. At least if you are older than 12 or so. One way to keep up the illusion of eternal youth is image manipulation. Today I explore one way to smooth skin and keep it looking natural. That’s the problem with overly done make up and postprocessing – if you overdo it, faces look like made out of plastic. There is a difference in size between “good” and “bad” skin structures. The Wavelet Decompose plugin can divide an image into “scales” and a “residual”. Each scale contains a part of the image with structures of a similar size. If you work on one of these scales, you are changing only these structures, not the smaller and larger ones. The plugin website does a better job of explaining this.
