Prompt

Apply a Duotone Mapping effect, replacing the full color palette with a continuous gradient from deep navy shadows to warm peach highlights. Map intermediate brightness into blends of these two inks, preserving readable contours, fine texture, and the existing lighting pattern. Keep the original subject and composition.

Paste it into LetzAI with your own image to apply the effect ↗
