Best Use Cases
- Old Photo Restoration — Remove dust and scratches from vintage photographs.
- Film Scanning — Clean up scanned film negatives and slides.
- Archive Digitization — Restore historical images for digital archives.
- Family Photos — Bring old family photos back to life.
- Print Restoration — Clean up scanned prints with surface damage.
Pro Tips
- Use Dust-Scratch V2 for better results on heavily damaged images.
- For archival work, export as PNG to avoid additional compression artifacts.
- Combine with other Topaz tools (Sharpen, Upscale) for complete restoration workflow.
- Best results come from high-resolution scans of the original photos.
Notes
- This model is optimized for dust and scratch removal, not for colorization or major damage repair.
- For best results, scan original photos at high resolution before processing.
- V2 model generally produces better results but may take slightly longer.
