Gray Card.

Coming Soon.

A scene-referred RAW photo editor for film and digital.

Gray Card allows you to edit photos using a high-level semantic model of depth, segmentation, and materials by parsing the photo into intrinsic layers of reflectance, illumination, and specular.

Hypo is Gray Card's metadata companion: a purely client-side web app that reads and writes your photo records in an atproto repository you own.
