Candid ultra-realistic birthday collage styled as authentic vintage Polaroid photos. Four square images in white Polaroid-style frames, arranged in a clean collage. Captured with a 50mm portrait lens at eye level, cropped waist-up. The young woman wears a white off-shoulder top, with long wavy hair. She is smiling while holding a cake with lit candles, blowing the candles with smoke drifting, laughing while eating cake, and sitting softly beside the cake. Tone & Texture: Tone & Texture: True Polaroid analog feel. Slightly faded colors, warm nostalgic tint. Visible soft film grain, natural imperfections like dust, light scratches, and subtle blur. Softer highlights, muted contrast (not HDR, not glossy). Candle glow looks natural and slightly diffused. Lighting & Mood: indoor warm ambient light with cozy candle glow, cinematic but imperfect, natural household atmosphere. Style: authentic vintage instant film aesthetic with organic textures, imperfections, and dreamy softness. Negative Prompt: overly clean digital look, harsh sharpness, HDR, plastic skin, no grain, no fade, sterile studio feel, watermark, distorted faces, wrong outfit.
