LR5 stores adjustments in it's catalog. Does it also store the adjustments inside the DNG format file or is it added only upon Export as a DNG file?
The default mode of operation of Lightroom does not store edits in the photo file.
You can optionally have the edit final conditions (but not the edit history) in the DNG or other photo file. Use Ctrl/Cmd-S or turn on the option to save the edits to xmp automatically.
