.dng — Digital Negative
Adobe's open raw photo container designed for long-term camera raw storage.
About this format
DNG is a camera raw container. It keeps sensor-oriented image data and metadata so photographers can edit exposure, white balance, color, and detail later.
Use DNG for archival raw workflows. Export JPG, PNG, AVIF, or WebP when you need a viewable or uploadable image.
