And how would that work if you had any normal camera (rather than a camera phone)What I was trying to say by that is that until the cell phone camera of convenience and even beyond it any actual normal camera seems to only record in the normal accepted landscape format and not in some sort of vertical format that really only came about because of essentially a mistake or laziness or cost cutting or just convenience factor of it all specifically for mobile phones and not because the format actually makes sense or has something to it (otherwise it would have existed in a fairly widespread existence long before).
I totally agree. The problem is that portrait-shooters have the phone in hand, the camera app is usually launched from a phone held in portrait mode, the phone has the lens at the top, and the person sees the image and hits record. Most people, whether they shoot in portrait intentionally or not, do not appreciate the difference and/or haven't the skills or desire to change it after the fact.
