Photo presets are broken. They copy someone else's color grade — not your eye, not your mood, not the way you see light. Photo Style Unifier works differently. Upload 3–8 reference photos you love. The app analyzes their perceptual signature: how shadows behave, where saturation lives, the relationship between tone and light — then transfers that exact sensibility to any photo. No sliders. No generic filters. No subscription. Free to preview. Pay only when you download.
