iphone 8+ camera

Thanks, Sravankra. I tried photo, portrait and square, while holding phone horizontally. When I tried to view picture holding camera horizontally the picture would rotate to a smaller image view.....not filling the screen with the horizontal picture. Sometimes the horizontal view shows in a small image when holding phone vertically, and then when I rotate the phone horizontally, the picture rotates to a full screen horizontal view....like it should.

Weird. I'm so confused. Now sometimes it's working the way I want and then not. Driving me nuts. I'd provide pictures but my husband's Android rotates them in a way I can't get across my point. Sheesh. Oh well. But there has to be a way to dictate how it you want it.
