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 applying the transformation.

TRANSFORMATION DESCRIPTION:
Transform the photo into a high-quality Soviet-era photography style portrait from the 1960s-1980s. The image should capture the authentic aesthetic of Soviet studio photography, characterized by specific lighting patterns, color rendering, and film characteristics typical of that historical period. The person should look like they were professionally photographed in a Soviet studio or official setting.

STYLE AND AESTHETIC PARAMETERS:
- Art Style: Photorealistic vintage photography with authentic film grain and texture
- Lighting: Classic Soviet studio lighting - soft, slightly flat frontal lighting with subtle shadow gradients. Typical of official portraits and studio photography from the era
- Color Palette: Warm sepia tones, faded Kodachrome-like colors, or desaturated color grading typical of Soviet film stock. Slight color shifts toward amber and brown tones
- Film Characteristics: Visible but subtle film grain, slight softness in highlights, authentic period-appropriate contrast levels
- Background: Simple studio backdrop - typically muted gray, beige, or dark brown. Can include subtle studio props like draped fabric or minimalistic setting
- Subject Pose: Slightly formal pose typical of official portraits - straight posture, direct gaze toward camera, neutral to serious expression
- Clothing Suggestion: If visible, suggest period-appropriate simple clothing styles (turtlenecks, plain shirts, simple dresses) without forcing changes
- Overall Atmosphere: Nostalgic, authentic, documentary-style, reminiscent of family albums or official Soviet photography

TECHNICAL QUALITY PARAMETERS:
- High resolution, 4K, detailed, professional quality
- Sharp focus on face with realistic depth of field
- Authentic film texture without artificial over-processing
- Natural skin texture preservation with vintage color grading
- Professional portrait composition following classic rules
- Aspect ratio: 4:3 (typical for vintage portraits) or 1:1 (square format)

NEGATIVE PROMPT GUIDANCE:
Avoid: distorted facial features, unrealistic proportions, blurry face, loss of likeness, over-saturated colors, modern digital filter look, Instagram-style effects, neon colors, futuristic elements, cartoonish rendering, excessive sharpness, HDR effect, bokeh overlays, lens flares, digital artifacts, unnatural skin smoothing, plastic look, contemporary fashion items

USER CUSTOMIZATION:

ADDITIONAL GUIDANCE:
- The transformation should feel authentic to the era, not like a cheap filter
- Maintain the person's identity as if they were photographed during that historical period
- The vintage effect should be subtle enough to preserve facial details while creating the appropriate atmosphere
- If the original photo has modern elements, they should be softened or adapted to match the vintage aesthetic without complete replacement
