Using Slo-Mo in iOS 26
Select Video, then swipe right on that Video|Photo bubble. 🎉 The slo-mo and time lapse options appear!
Select Photo, then swipe left on the bubble. 🎊 The portrait and pano options are there!
Now that I know about this, I saw there is a tiny visual hint shown when changing between video/photo. Then, after a brief moment, it turns back into the shape that implies video|photo are the only choices.
(When I couldn't figure out where it was, I searched the internet, which was entirely slop saying the feature didn't exist. Thanks for nothing, tech overlords!)
