Expanded exposure record notes
It would be cool to be able to take scene reference pictures and metering point notes. Perhaps you could even place spot metering annotations directly on the reference pictures.
Saving the location will definitely be added once the exposure notes are expanded. In fact, the exposure records already have a place to store this - it's just not being filled in or shown yet.
It would be be nice if a line or two were added to the notes showing the GPS location. My Iphone 4 has GPS, so I would think that the newer phones has it also. Getting this information from the phone and adding it to the notes would seem like a simple thing to do (probably an over simplified statement). In reading online about geotagging photos, it doesn't seem like it's a clean, easy operation.
