I use to drive my art professors crazy over these "artistic" ratios.
Maybe they were dinosaurs that once ruled the earth but once the printing press came about... Now, fossils.
The majority of human's visual attention now starts automatically at the top left corner of images and surfaces with information. So why the hell wouldn't I use that information to guide my decisions on how to lead the eye through a composition instead of a math trick?!?
I think the bigger disconnect is in what an artist's goal is. Personally, I'm more of a storyteller than a fine artist. I understand the tools in an artist's toolbox, but they serve me...I don't serve them.
