| Fixture findings | Denoising and text edges were retained; the tested free tier was limited to 2× at 1024px. | Text was clear in this 4× output; the free-credit image carried a brand watermark. |
| Original historical observation | DeWatermark Image Enhancer's 2X model prioritizes faithful denoising and edge sharpening, scoring PSNR = 27.12 dB overall and 30.46 dB on the engraved wooden sign without hallucinated textures, though 4X (2048×2048) is locked behind Pro. | 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. |
