Horizon Zero Dawn and Shadow of the Colossus had me use the photo mode all the time. Setting the time in HZD in photo mode was a great feature just to play around with. In SotC you could make the most beautiful wide shots.

However after SotC I came a bit disillusioned with photo modes. The pictures taken on my HDR screen look kinda washed out on a non HDR screen and/or details go missing in lower and higher ranges. Any videos I make from GTS on my HDR tv look kinda off color wise which it warns you about anyway. HDR is beautiful, HDR capture is not. I guess that problem won't be solved until HDR is standard on all screens.
