Keep those protected elements crisp, photographic, and in their original colors.\nBackground treatment: redraw every unprotected background element as monochrome linework on white paper, with convincing contour lines, cross-hatching, graphite shading, and subtle construction marks. No color may remain in the background.\nEdge treatment: create a precise separation around hair, clothing, fingers, legs, and protected objects; prevent sketch texture or grayscale spill from crossing onto the person.\nComposition/framing: preserve the original crop, camera angle, perspective, and subject placement.\nConstraints: change only the background medium; do not add or remove scene elements; no border, text, logos, or watermarks.","author":{"@type":"Organization","name":"Picoprompt","handle":"picoprompt","official":true},"genre":"Image","dateCreated":"2026-09-09T04:10:00.000Z","url":"https://picoprompt.app/p/ink-behind-you","usage":{"model":"Image model with editing support","variables":["sketch_medium"]},"examples":[{"name":"City in graphite","sourceImage":"https://picoprompt.app/examples/main-cyclist-source.png","sourceImages":[{"label":"Source image","image":"https://picoprompt.app/examples/main-cyclist-source.png","alt":"A woman with a bicycle standing on a sunlit city street"}],"outputImage":"https://picoprompt.app/examples/sketch-cyclist-output.png","sourceAlt":"A woman with a bicycle standing on a sunlit city street","outputAlt":"The same woman and bicycle in full color against a black-and-white architectural sketch"},{"name":"Botanical linework","sourceImage":"https://picoprompt.app/examples/main-gardener-source.png","sourceImages":[{"label":"Source image","image":"https://picoprompt.app/examples/main-gardener-source.png","alt":"An older man watering plants in a greenhouse"}],"outputImage":"https://picoprompt.app/examples/sketch-gardener-output.png","sourceAlt":"An older man watering plants in a greenhouse","outputAlt":"The same gardener and watering can in color against a monochrome botanical sketch"}]}
