The core innovation of Portraiture was its "Auto-Mask" feature. Upon launching the plugin, the software would analyze the image and automatically generate a mask based on the hue, saturation, and brightness values typical of human skin. In a CS3 workflow, creating such a precise mask manually would take a skilled retoucher upwards of twenty minutes. Portraiture achieved it in seconds. This allowed the software to apply smoothing and tonal adjustments selectively to the skin while leaving eyes, lips, hair, and background details sharp. It was an early form of what modern AI tools now call "semantic segmentation," applied years before artificial intelligence became a marketing buzzword.
