Thanks for the very detailed explanation, it’s very helpful.
I think I understand it better now: if I use aperture or shutter priority then it seems to report that correctly under Exposure Program. However, if I use program mode P it just reports “Normal” in the info panel but “Program AE” in the flip panel. Panasonic’s full auto mode – iA – seems to report a number of things, often “Landscape” because that presumably is the type of scene the camera is intelligently assessing as the content.
Orientation on the other hand doesn’t seem to use “Landscape” at all but usually “Normal” with portrait images being reported as “90deg Counter-clockwise” or similar.
There is also something called “Shooting Mode” but I’m not sure how that fits in. It reports various things such as “Program” or “Scenery”.
I’m still not 100% clear what the heart does. When I select the EXIF button I still have to scroll through a huge list to see any items I’ve checked with a heart. It doesn’t appear to reduce the list as you describe.
Incidentally what is the meaning of “increased precision for some Exif Keys” in Settings?
