+1 for 3:2 shooting I've just ran into this issue. First year we ditch the camera the to rely only on phones. (4:3 or 16:9) When I sorted/edited our pictures in December it turned out that many good looking pictures where impossible to arrange nicely for 10x15cm prints. 3:2 shooting at highest resolution with 3x3 grid is absolutely necessary. I don't mind if a few useless pixels are cropped out is 10x15 printing won't be ruined
