IDENTITY PRESERVATION INSTRUCTION:
Using the uploaded photo as reference, preserve the person's exact facial features, face shape, eye color, skin tone, and unique characteristics while transforming the scene. Maintain the distinct identity of both individuals in the couple, ensuring their recognizable traits remain clear and unaltered.

TRANSFORMATION DESCRIPTION:
Transform the photo into a high-quality vintage couple portrait. Apply a nostalgic aesthetic that mimics classic film photography from the mid-20th century. The couple should be posed naturally, perhaps in a soft embrace or standing close together. Clothing should be adapted to a vintage style (e.g., 1950s-1960s era suits, dresses, or formal wear) that suits the individuals' body types. The overall mood should be romantic, timeless, and elegant.

STYLE AND AESTHETIC PARAMETERS:
- Art style: Photorealistic with a vintage film photography look. Subtle film grain and soft focus edges to mimic old cameras.
- Lighting conditions: Soft, diffused studio lighting or warm natural window light typical of vintage portraits. Gentle shadows on faces to add depth.
- Color palette: Muted, warm tones. Options include sepia, faded Kodachrome colors, or desaturated pastels. Avoid overly vibrant modern colors.
- Background treatment: Simple, classic studio backdrop (e.g., textured fabric, soft gradient) or a subtle vintage interior setting (like a retro living room corner). Background should be slightly blurred to keep focus on the couple.

TECHNICAL QUALITY PARAMETERS:
- High resolution, 4K, detailed
- Sharp focus on faces
- Professional quality portrait
- Aspect ratio: 1:1 (square) or 4:3 (classic portrait ratio)

NEGATIVE PROMPT GUIDANCE:
Avoid: distorted facial features, unrealistic proportions, blurry faces, loss of likeness, modern clothing items, digital artifacts, over-saturated colors, harsh lighting, unnatural poses, low resolution, pixelation.

FINAL INSTRUCTIONS:
Ensure the transformation feels authentic to the vintage era while keeping the subjects' identities perfectly intact. The image should look like a professionally taken portrait from the 1950s or 1960s.
