Keep an eye on

This is continuous-tone duotone; it intentionally differs from misregistered risograph printmaking.

Make it yours, step by step.

1. Adjust the recipe to describe your subject and preferred background.
2. Copy the complete recipe, then open ChatGPT.
3. Upload your photo in ChatGPT and paste the recipe. The short code alone is not an official command.
4. Inspect identity, text and proportions. Ask for a targeted correction if needed.

Choose the change deliberately.

Choose two colors with enough tonal separation to describe the face. A duotone is easier to read when the darker ink carries shadows and the lighter tone supports highlights.

Review and refine the result

Check eyes and hairline after the color mapping. If facial planes flatten, increase tonal separation rather than adding more colors. Keep skin texture where it contributes to recognition.
