## Key Takeaways for Wedding Photo Sorting
|
|
|
|
1. **LAION Aesthetic Predictor V2 is the simplest starting point** — one-line Python API, MIT license, ~2 GB VRAM, fast inference. But it scores "aesthetic appeal," not "technical quality." It will NOT detect blur, out-of-focus shots, or bad exposure.
|
|
|
|
2. **Best approach: Combine models.** Use BRISQUE/NIQE for technical quality (blur/noise detection) + LAION V2 or MUSIQ for aesthetic scoring. A photo should be kept only if it passes BOTH thresholds.
|
|
|
|
3. **MUSIQ is the best single-model option** if you want one model that captures both aesthetic and technical quality. It's from Google Research, handles full-resolution images, and has Apache 2.0 license.
|
|
|
|
4. **SigLIP V2.5 is a modest improvement over LAION V2** — better on illustrations/art, but same fundamental limitations for real photography. Worth trying if you have BF16 GPU support.
|
|
|
|
5. **No open-source model understands wedding context.** None of these can distinguish a "peak moment" from a "transitional shot" or detect emotional content. For that, you need commercial tools like FilterPixel DeepCull (genre-specific AI) or Aftershoot (learning-based).
|
|
|
|
6. **For 4,000 wedding photos on a consumer GPU (RTX 4090):**
|
|
- LAION V2 batch: ~5-10 minutes
|
|
- MUSIQ batch: ~15-20 minutes
|
|
- BRISQUE (CPU): ~10-20 minutes
|
|
- Combined approach (LAION + BRISQUE): ~15-25 minutes total
|
|
|
|
7. **Bias warning:** LAION V2 has documented Western/cultural bias. For culturally diverse weddings (e.g., Indonesian, South Asian, African), scores may not accurately reflect the quality of ceremony shots, cultural attire, or traditional poses.
|
|
|
|
8. **Practical recommendation:** Start with LAION V2 + BRISQUE as a first-pass filter. Score all 4,000 images, set thresholds (e.g., LAION > 5.5 AND BRISQUE < 30), and manually review the borderline cases. This reduces 4,000 images to ~500-800 for manual review.
