So apparently, some people on PC are having difficulties figuring out how to hop into the photo mode added with the next-gen update. The truth is: you can't, because your game (for whatever reason) doesn't recognize a critical set of input configurations, omitting it from your profile entirely. I'm not sure why this happens (especially since not everyone seems to be affected) but here's how to fix it:
Save the file, start your game and enjoy photo mode!
- Navigate to your config file location: %USERPROFILE%\Documents\The Witcher 3\
- Open the file input.settings with a text editor of your choice.
- Copy the following block of text (see below) and paste it at the very end of that file.
- OPTIONAL: feel free to change the key bindings under [PhotoModeTrigger] to any key of your preference (e.g. changing IK_U to IK_F3 will bind it to F3)
