CR2 Converter

CR2 is the raw file a Canon camera writes: sensor readings, plus the shooting settings stored as notes instead of baked into the picture. Nothing has been demosaiced or contrast adjusted yet, so you can reset white balance, pull back a blown sky and grade color later without the damage those edits cause in a JPG. The costs are size and compatibility. CR2 files are heavy, and many programs and upload forms will not read them, so photographers export a JPG or TIFF copy for everyone else.
