Portraiture smooths and softens an image by removing artifacts while preserving skin texture and other important image details such as hair, eyebrows, eyelashes etc. To achieve the desired result, you can adjust the smoothing degree for different detail sizes - fine, medium and large.
Additionally with the "Portrait Size" parameter Portraiture adjusts the smoothing
parameters to achieve the most visually compelling result for different portrait sizes.
