In general, there are four “famous” skin-retouching techniques on the photography and retouching market to achieve a smooth skin:
- Gaussian blur (for me not a skin-retouching technique, but I see it a lot)
- Inverted high-pass
- Frequency Separation
- Dodge & Burn
(Yes, there are more, but these are the “biggest” ones “inside” Photoshop)
This article will compare these skin-retouching techniques to show the pros and cons for each of them. However, this article will not show you how to do them, but what the “good and bad” sides are about these techniques – they might be not “black or white” but can be both (like grey-shades).
