🔍 About This Code Showcase
This curated code snippet demonstrates how the Polaroid Moments Generator blends two personal images into cohesive vintage compositions with authentic Polaroid aesthetics and multiple pose variations.
Full deployment scripts, API integrations, and proprietary details are omitted for clarity and security. This showcase highlights the core image fusion algorithms and vintage style transfer techniques.
🎨 Core Algorithm: Dual Image Fusion Engine
The heart of the Polaroid Moments Generator is its ability to intelligently blend two separate photos into cohesive vintage compositions. Here's the core implementation:
import { GoogleGenerativeAI } from '@google/generative-ai';
interface PoseVariation {
arrangement: string;
composition: string;
relativePositioning: string;
intimacyLevel: number;
}
class PolaroidFusionEngine {
private genAI: GoogleGenerativeAI;
private poseTemplates: PoseVariation[] = [
{ arrangement: 'side_by_side', composition: 'shoulder_to_shoulder',
relativePositioning: 'equal_height', intimacyLevel: 0.7 },
{ arrangement: 'embracing', composition: 'one_arm_around',
relativePositioning: 'slight_lean', intimacyLevel: 0.9 },
{ arrangement: 'back_to_back', composition: 'playful_stance',
relativePositioning: 'mirror_heights', intimacyLevel: 0.5 }
];
constructor(apiKey: string) {
this.genAI = new GoogleGenerativeAI(apiKey);
}
async generatePolaroidMoments(image1: File, image2: File): Promise<string[]> {
"""
Blend two separate photos into multiple Polaroid-style compositions.
Maintains facial identity while creating natural-looking togetherness.
Args:
image1, image2: The two individual photos to blend
Returns:
Array of base64-encoded Polaroid-style images with different poses
"""
const analysis1 = await this.analyzeSubject(image1);
const analysis2 = await this.analyzeSubject(image2);
const blendingStrategy = this.calculateBlendingStrategy(analysis1, analysis2);
const polaroidMoments: string[] = [];
for (const pose of this.poseTemplates) {
const fusionPrompt = this.buildFusionPrompt(pose, blendingStrategy);
const result = await this.model.generateContent([
fusionPrompt,
{ inlineData: { data: await this.convertToBase64(image1), mimeType: image1.type } },
{ inlineData: { data: await this.convertToBase64(image2), mimeType: image2.type } }
]);
const polaroidStyled = await this.applyVintageEffects(result, pose);
polaroidMoments.push(polaroidStyled);
}
return polaroidMoments;
}
private buildFusionPrompt(pose: PoseVariation, strategy: any): string {
return `Create a single vintage Polaroid photo showing both people together in a ${pose.arrangement} pose.
Composition: ${pose.composition} with ${pose.relativePositioning} positioning.
CRITICAL REQUIREMENTS:
- Maintain exact facial features and identity of both people
- Blend lighting naturally so they appear photographed together
- Use authentic 1970s Polaroid aesthetic: warm tones, soft focus, film grain
- Add classic white Polaroid border with subtle aging
- Ensure pose looks natural and candid, not forced
- Match skin tones and adjust for consistent lighting
Result should look like an authentic vintage Polaroid from a real moment.`;
}
}
🎞️ Vintage Style Transfer Pipeline
The authentic Polaroid aesthetic requires sophisticated color grading and film simulation to recreate the distinctive look of instant film:
class VintageProcessor {
async applyPolaroidAesthetic(imageData: string): Promise<string> {
"""
Apply authentic Polaroid film characteristics to the generated image.
Recreates the distinctive color palette, grain, and border of instant film.
"""
const colorGraded = await this.applyPolaroidColorGrading(imageData);
const grainAdded = await this.addFilmGrain(colorGraded, {
intensity: 0.15,
pattern: 'organic',
colorVariation: 0.08
});
const softFocus = await this.applySoftFocus(grainAdded, {
radius: 1.2,
preserveDetails: true
});
const withBorder = await this.addPolaroidBorder(softFocus, {
borderWidth: 40,
agingLevel: 0.3,
yellowTint: 0.12
});
return withBorder;
}
private applyPolaroidColorGrading(imageData: string) {
"""Apply the distinctive warm, muted color palette of Polaroid film"""
const colorAdjustments = {
temperature: +200,

};
return this.processColorChannels(imageData, colorAdjustments);
}
private addFilmGrain(imageData: string, options: any) {
"""Add organic film grain that mimics silver halide crystals"""
const grainPattern = this.generateOrganicGrain({
