ColorMatrix1 Fix
Some phones and cameras write a broken ColorMatrix1 tag into their DNG files, which shows up as a color cast (often pink or green) in raw editors. This tool reads that tag and lets you fix it.
Your files never leave this device. Everything here — reading, editing, and fixing the DNGs — runs locally in your browser. Nothing is uploaded to any server.
