Nano Banana Pro

Image Transformation to Minimal Vector Poster

A complex, structured prompt for Nano Banana Pro designed to transform an existing image into a clean, minimalist vector-style poster. It mandates geometric simplification, a restricted color palette (3–6 colors, no gradients), flat lightin

{ "task": "Transform the provided image into a minimal vector-style poster.", "style": { "overall_look": "Flat-design, geometric simplification, minimalist vector art", "color_palette": { "type": "restricted", "description": "Use a reduced palette of 3–6 harmonious colors with clean tonal separation and no gradients.", "constraints": [ "No photorealistic rendering", "No texture or noise", "Avoid excessive detail" ] }, "shapes": { "treatment": "Reduce all forms to essential geometric contours and solid shapes.", "linework": "Use clean, even-weight line art or optionally no outlines depending on poster coherence.", "abstraction_level": "High, but not so high that the subject becomes unrecognizable." }, "lighting": { "handling": "Remove realistic lighting. Replace shadows and highlights with simplified, flat blocks of color or omit them entirely.", "allowed_effects": ["Hard-edge shadow shapes", "Subtle tonal areas"], "forbidden_effects": ["Soft shadows", "Complex reflections", "Photographic highlights"] } }, "subject_preservation": { "identity": "Maintain recognizable identity through silhouette, proportions, key facial landmarks, and essential features.", "proportions": "Keep accurate relative scale of body, head, and major elements.", "essential_details": [ "Define only the most important features needed for recognition.", "Remove fine texture, hair strands, pores, and small clothing details." ] }, "composition": { "framing": "Match the original crop unless specified otherwise.", "background": { "treatment": "Simplify into 1–2 large flat color fields or abstract geometric forms.", "forbidden_details": ["Real textures", "Complex scenery", "Photographic depth of field"] }, "hierarchy": "Subject should remain the focal point, with background serving as supportive minimal structure." }, "color_and_balance": { "poster_aesthetic": "High clarity, bold contrast, and legible silhouette.", "white_balance": "Neutral; avoid warm or cool photographic shifts.", "edge_integrity": "All edges must be crisp, clean, and consistently stylized." }, "output_requirements": { "format": "Flat, poster-like vector appearance (though raster output is acceptable).", "resolution": "Match original image resolution unless otherwise instructed.", "consistency": "No added text, logos, watermarks, or elements not present in the original." }, "prohibited_changes": [ "Do not alter identity.", "Do not add new objects or remove essential ones.", "No stylization that contradicts minimal vector aesthetics (e.g., painterly strokes, gradients, 3D shading)." ], "goal_summary": "Create a clean, minimalist vector-style interpretation of the original image, preserving silhouette, proportions, and essential identity while removing all non-essential details and realistic lighting cues." }
