That's it.★ No custom nodes to install★ No OOM / VRAM crashes★ Original colors &amp; lighting 100% preserved★ Full image — no stretching, no cropping (v5 mode)★ Works on NVIDIA / AMD / Apple Silicon▌ THE SECRET─────────────ESRGAN ×4 upscales your image from 1024px → 4096px, recoveringevery fine detail. ImageScaleBy ×2 then scales proportionally to~8192px — no stretching, no cropping, no color shifts.Original lighting and colors are 100% untouched.━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ PIPELINE━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 01.

Output saved to: output/8K_OUTPUT/enhanced_8k.png━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ PRO TIPS━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ★ Best input: start with at least 512×512px. Higher input = better 8K output detail. ★ Portrait photos: use v5 (Original) — ScaleBy preserves the full portrait without any face cropping. ★ Wallpapers &amp; landscapes: use v4 (Fill) — crops to a perfect 16:9 8K for your display. ★ Low VRAM (4GB)? Downscale your input to 512px before running. ESRGAN still outputs beautiful 8K results.━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ LICENSE━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Free for personal and commercial use.
