Makes sense!

How do you save to JPG in stand-alone mode? I can't find any option to
select the file type, and when I click the "Save" button, it saves to
a .ppm file (that has absolutely no EXIF data at all).

These tags are present in all camera-generated files, whether DNG,
PEF, TIF or JPG. I only use PhotoME to confirm my camera's firmware
whenever Pentax issues a silent firmware update (which they do
frequently). It's the only way to see what specific firmware version
is actually in the camera.

Attached is a screenshot of just some of the extra data displayed by PhotoME.
