Shoot first. Focus later: Live Focus lets you add realistic depth and cinematic focus to ANY IMAGE, after it’s already taken. Photos, illustrations, AI-generated images, and even images from decades ago. If it’s an image, Live Focus can bring depth to it. No special camera or device. Just focus everything, reimagined. What you can do: - Refocus photos after shooting - Create cinematic background blur - Adjust focus point and depth intensity - Apply realistic depth to AI-generated images - Bring old photos and artworks back to life - Preview focus changes instantly Live Focus is expanding beyond single images. Support for serial media such as video is planned, bringing the same refocusing and depth experience to moving moments. Through this project, our long-term goal is to reconstruct past moments from ordinary photos and videos, enabling a new kind of spatial vision experience — where depth, perspective, and presence can be explored, even when they were never originally captured.
