EXIF: the EXchangeable Image File format protocol is defined by the JEIDA (Japan Electronic Industry Development Association), which includes not only camera manufacturers, but also image processing application publishers (including those outside of Japan).These are official protocols adopted by the international image and publishing industry: In photo software in general, and in DxO PhotoLab in particular, you will find two types of metadata: EXIF and IPTC. The saving of metadata is automatic and executed in real time. They are also saved in the DxO PhotoLab database.
