Haven't done much printing in the past few months, but I tend to find myself liking photos that aren't the standard 2:3 proportion.I think it just looks too much like a snapshot.
For whatever reason, and I'm sure there's some research somewhere that would explain it, I like images with either a square proportion or that are pushing panoramic. I've done several 12x24 inch prints and keep coming back to that size.
Aside for history, is there really any reason to stick with 2:3? Guess as it's a standard there are frames and such already available.It was tough to find glass for a 7.5x54" panoramic I did a few years ago.
