AI Photo Colorization

AI Photo Colorization

Concept

Authentic reconstruction, not manual tinting.

We bring the memories sleeping inside black-and-white photographs back to full color with AI.
As an AI development company, we apply our own AI technology to photo colorization.
Rather than overlaying generic color, we reconstruct the moment the photo was taken.

Difference

How is this different from traditional colorization?

Traditional Hand-Tinting

  • Color applied manually, area by area
  • Tends toward a flat, hand-painted look lacking depth
  • Color choices are subjective and interpretive
  • Direction of light and material textures rarely come through
Retouch Ink

Our AI Colorization

  • AI automatically analyzes light source, materials, and historical context
  • Reconstructs the colors of the era, rather than guessing them
  • Skin tones, fabric textures, and atmospheric depth rendered close to what the eye saw
  • AI correction also optimizes overall tonal range and contrast

Kimono and Western dress side by side (September 1945)
Everyday life just after WWII

Colorization Highlights

  • AI inferred the kimono's color pattern from its dyeing and design
  • The natural straw-yellow of the hat and the texture of sun-tanned skin expressed
  • Even complex scenes mixing kimono and Western clothing remain consistent

Built by an AI development company

We also build AI products in-house, with deep expertise in image recognition and generation. Our AI model is tuned specifically for colorization — rather than just applying color, it analyzes the subject's materials, lighting, and historical context to reconstruct colors close to what the eye would have seen.

Composition stays untouched

We preserve every detail of the original photo and add only color. The composition and expressions remain exactly as they were. We also handle final-look review and color fine-tuning so you don't end up with results that miss the mark.
