@Ederporto: couldn't you use heading (P7787)? and if not, what is the difference? Cheers, VIGNERON (talk) 15:54, 25 March 2020 (UTC)[reply]

@Puik: any thoughts or input? I'm also curious how you can validate reliable data here - isn't it guesswork in most cases? Do digital cameras store this data? Spinster 💬 08:59, 25 March 2020 (UTC)[reply]
- Smart devices do, yes, but in 3D – yaw, pitch, roll. I'm curious why should this property be called tilt and not direction of view or view azimuth or smth? Tilt has another meaning in photography. Puik (talk) 09:08, 25 March 2020 (UTC)[reply]
  - Property seems useful, but also "direction of view" or something like that seems a better name for it. Kruusamägi (talk) 11:23, 25 March 2020 (UTC)[reply]
