I agree with basically everything you said, yet I take quite a few pictures during my trips; a cheap phone shot that takes as little time as possible, that may be awfully blurry and with horrible colors, but that is enough to get the relevant information. Which is:

- Get a quick access to references that are mentally organized (because of the trip), without having to take time to actually gather the pictures.

- The specific element might not be photographed, or not possible to find at least. Maybe it's the design of some doorknob that's really great, in the middle of the countryside. Good luck finding that on google. Even some painters in the rijksmuseum are impossible to find on the web, so...

- Nothing existing picture may be satisfying. Maybe the specific arrangement of shapes works best from a very specific point of view. Maybe it's because of the lightning conditions. There are many potential reasons.

- You can use the ref without fear of copyright infringement (well, orwellian states would differ, but nearly).
