Original detail was not sufficiently recovered
In these three cases, fine hairs and brushwork were not fully recovered, and contours also changed. Faithful restoration was not demonstrated under these conditions.

AI upscaling & retouch, compared
Compare contours and texture in the input, AI upscale and retouch at the same position and scale. The high-resolution reference provides a basis for inspecting the original details.
01 /
Choose an image — reduced previews
Select the original or any processing stage independently on either side. All views use the same image coordinates and scale. At 100%, one source pixel corresponds to one CSS pixel. Scroll larger views within each frame; the three detail views pan together.

Three views of the same region
The high-resolution reference and your selected left and right images. Region, scale and blend settings follow the comparison above. Scroll within each frame when an image is larger than the frame.

What the comparison shows
Lower strengths reduce the changes
A weaker blend stays closer to the AI upscale. Reducing a change and recovering the original detail are separate outcomes.
Lines and a signature also changed
The abstract painting shows changes to a band position and signature. Natural appearance alone cannot establish preservation of shape and content.

Method, display guide & limitations
- Each high-resolution reference is a 2048 × 2048 px crop, provided as a basis for comparing the original contours and texture.
- A 512 × 512 px input is upscaled by AI to 4×, then retouched. The resulting stages are compared here. Processing conditions are described in the method and credits.
- The input image is displayed with each of its 512 px pixels repeated 4×. At 100%, one pixel of the 2048 px image corresponds to one CSS px on screen. All panels use the same crop coordinates and display scale.
- Blends are saved composites of the AI upscale and retouch. Choose a full-image mask, a hard boundary or a 24 px inward feather, at 0 / 10 / 25 / 50 / 100%. Pixels outside the mask retain the AI upscale.
This comparison covers three images and one retouch run per image. Generalization, artist acceptance, production quality, labor and cost have not been evaluated.
