| Original historical observation | PSNR=25.77 dB · SSIM=0.9605 · edge_corr=0.6507 · hf_ratio=0.7040: unlike diffusive enhancers that heavily alter lighting and geometry, Leonardo's Aurora Precise mode injects rich high-frequency detail while preserving 0.9605 SSIM structural consistency. | PSNR=27.02dB · SSIM=0.8631 (4x 2048×2048 Prime model); outstanding edge_corr=0.7108, hf_ratio=0.7910, and plate_psnr=17.25dB with razor-sharp 'REALTEST 2026' and 'REALTEST 2048px GT' typography, though free-credit exports include a bottom-left Let's Enhance watermark. |
| Suitable uses · historical assessment | Designers and AI artists who want the best balance between generative micro-texture sharpening (`hf_ratio=0.7040`) and structural fidelity (`SSIM=0.9605`), with ~30 free upscales per day | Print and design professionals who need ultra-crisp 4x–16x texture restoration and are willing to subscribe to remove the watermark |
