Why not? I used to do it all the time on my iPhone? I still have situations where I need to do this. It's clearly a realistic use case if I have a need to do it and my previous device did it successfully.
I'm done with the apologists. Enjoy the only weak point of this device. The camera is not good, it's adequate.
Fine, remind me not to trust you opinion on anything to do with cameras and photography. I would guess that you may convince the uninformed with your talk but those who know better can look at the links I provided earlier are just look at shots in the camera sticky to see that the camera is quite capable and much better than adequte. To call it the weak point of the phone is laughable.
If your complaint boils down to I can't crop 70% of the image and still get a shot that looks good at full screen, then I don't think you will find much disagreement. But while you may say it is a reasonable use case, it doesn't fit with the purpose of the camera, which was to allow good low light performance, responsiveness, adn incredibly fast FPS. It is like the old car racing saying "fast, reliable, and cheap, choose 2". In this case you have "low light performance, cropable, fits in a phone, choose 2".
I am definately not an apologist. I have pretty high standards for photography. The camera has exceeded my expectations. If it was merely adequate I would be disappointed and I would have no qualms about trying a different phone that reasonable could have a better camera. There just isn't one available. Not on iOS and not on Android.
I have a Canon DLSR and a Sony RX100 22mp large sensor pocketable compact that I love. This phone allows me to leave both at home most of the time. Both the Canon and the Sony obviously much better cameras and are much better for low light, particularly if a flash is needed, have better dynamic range, and are necessary for times when a longer focal length is needed. Otherwise I am more than happy with the One camera and the quality of the images it produces. It certainly is easier to carry, share files from, and is much more fun to use.
