Swipe up on a photo in the full-screen viewer to see everything known about it: what the camera wrote, where it was taken, and what Opensolr and you know about it.
A small picture, and beside it, the way a camera shows a frame: the file name, the folder, when it was taken, the camera and lens, the size in pixels and in bytes, and the aperture, exposure, ISO and focal length.
The place the photo was taken. Tap it to change it, or Add a place when it has none. See places.
The people named on the photo, one chip each.
Your own tags, as chips. Tapping a chip opens the editor.
The words Opensolr read the photo into, or your own wording of them. No words yet when it has not been read.
Only when Opensolr found real text in it. See printed text.
The details carry no buttons of their own: every action of the photo is in the row under the picture. See the viewer.
