Replace Countertop Material

ROLE
Act as a professional architectural photo editor and interior visualization specialist. Treat the uploaded source photograph as the authoritative reference for identity, geometry and all content outside the requested change. Make a controlled image edit, not an unrelated new image.

EDIT
Replace the surface material of [COUNTERTOP AREA] with [COUNTERTOP MATERIAL].

PRIMARY OBJECTIVE
Preview a new countertop material with the original counter shape and fixtures. Keep the requested transformation visually clear while preserving recognizable identity and the source photograph's natural character. The edit-specific instructions define the allowed scope; do not extend a narrow request into a full makeover.

EDITING PRIORITY
1. Identify the requested target and apply only the selected transformation.
2. Preserve all untargeted objects, geometry and readable content.
3. Integrate changed surfaces or objects with correct perspective, lighting and occlusion.
4. Inspect fine boundaries and preserve the source's natural detail.

EDIT-SPECIFIC INSTRUCTIONS
- Preserve countertop outline, thickness, overhang and edge profile.
- Map grain or veining coherently across the top and exposed edges.
- Retain sink, cooktop and tap cutouts with exact positions.
- Preserve appliances, utensils and their contact shadows.
- Render gloss or honed reflectance appropriate to the chosen material without changing room lighting.
- Do not alter cabinetry, backsplash or floor; this image is not a measurement or fabrication plan.

STRICT PRESERVATION RULES
- Preserve the source composition, camera position, crop, aspect ratio, perspective and all content outside the requested edit. A requested change to lighting, geometry, materials or placement is permitted only within its described scope.
- Preserve untargeted people, animals, objects, accessories, permanent features and readable markings.
- Do not introduce additional subjects, props, logos or decorative text beyond the requested edit.
- Where an intentional change exposes a previously hidden area, reconstruct only what is necessary from adjacent visual evidence; do not invent unrelated features.
- Keep the effect confined to its intended area and directly connected shadows, reflections or occlusion. Do not apply unrelated beauty retouching, global grading or sharpening.

REALISM & INTEGRATION
- Match perspective, relative scale and attachment or ground contact to the scene.
- Make lighting and reflections coherent with the target material and the requested transformation. Preserve unrelated light sources and their effects.
- Use clean but natural boundaries. Maintain appropriate hair, fur, textile or surface detail rather than smooth cutout edges.
- Match focus, blur and grain to the surrounding image unless the requested style explicitly changes them.

ARTIFACT PREVENTION
Avoid warped geometry, duplicated parts, smeared textures, broken reflections, halos, inconsistent scale, mismatched focus and corrupted text. Do not make detail sharper or more elaborate than the source supports. Respect the specific stylization requested without letting it change unrelated content.

QUALITY CONTROL
Compare the edited result directly with the source. Verify the requested target and each edit-specific rule, then inspect boundaries, attachment points, perspective, contact shadows and material reflections. Check all visible text and numbers against the source or explicit user input. Confirm that no unintended object, missing component, extra label or unrelated redesign appeared. If the source does not reveal the target sufficiently, preserve uncertain content rather than inventing a confident reconstruction.

OUTPUT
Return one final edited image only at the original aspect ratio. Follow the framing rules above. Do not add captions, explanatory text, watermarks, borders or before/after comparison panels.
