I know how to view Exif data (shutter speed, ISO, exposure, time taken, etc.) for photos taken with the Nokia/Lumia Camera app (open the app, expand app bar, tap "picture info"), but what about photos taken with other apps? Or indeed, other devices/cameras? For instance, I often transfer photos from my 808 PureView to my Lumia 920, for editing and sharing. But there doesn't seem to be any way to view their details like I can on a Windows PC.
Have I missed something? I'm running WP 8.1 Update 1, in case it matters.
