How Photo Colorization Works: The Technology Behind the Magic
Ever wondered how old photos are transformed into vibrant color images? Learn about the AI technology that makes it possible.
The evolution of colorization
Early photo colorization relied on artists painting over prints by hand. Today, neural networks analyze millions of reference images to predict realistic hues for skin, clothing, and scenery.
Modern AI models learn from historical references to respect the era of your photograph while adding vibrant, believable tones.
How AI brings colors to life
PhotoRevive uses deep learning to detect edges, textures, and lighting, then assigns color values pixel by pixel. Confidence scoring ensures uncertain regions stay subtle instead of over-saturated.
The result is a natural-looking image that still feels true to the original moment captured on film.
