File sizes One argument is that DNG file sizes are more efficient and can be up to 20% smaller.

Backing up images will take longer In Lightroom, many of the changes you make can be stored in small XMP sidecar files that accompany raw files, and are only a few kilobytes. Do you really think that Adobe knows everything that’s in every proprietary RAW file format it supports?Ģ.
