The filters available in this app include Detail, which sharpens textures and makes features stand out; Edge Enhance and Edge Enhance More, which accentuate edges for a defined look; Smooth and Smooth More, which soften the image and reduce imperfections for a polished appearance; and Sharpen, which increases contrast and clarity to reveal finer details. Together, these filters allow users to transform their photos, emphasizing beauty and enabling unique artistic interpretations, making face filtering an engaging way to manipulate images and express creativity."
