I have a Big Question to ask, but no answers. I’m just thinking through my keyboard.
Consider, for the sake of argument, Instagram — not to heap blame on Meta, but as a starting point. Instagram privileges, by visual design, not square photos but portrait-format images. On an individual’s feed, anything not taller than wide is cropped arbitrarily. That change, made a year or so ago, annoyed a lot of people, but it’s a local consequence, if not an inevitable one, of the smart phone as viewing device: you’re working within a portrait-format medium.
Imagine you’re scrolling vertically through images on a vertically oriented device. The images you will see for the longest duration, which therefore will make the greatest visual impression on you, will get the most attention, and will therefore be served algorithmically most often to others, are those that take up the most physical space on the vertical screen — that is, those in portrait format.
But again: it’s not the algorithm. It’s the medium. The algorithm makes the problem worse, but it starts with the fact that the phone is a vertical device.
This is a fairly radical change from the way the world was presented in 20th-century media, especially in film: in a horizontal orientation that showed context within a room or across a landscape. And those media, importantly, reflected the way (I think) normal human beings take in their surroundings. If you’re walking around you see what’s in front of you, and you also scan left to right; not so often up or down, I think, unless the ground is uneven or a bird is singing in the trees. We don’t naturally move up and down, but across horizontal surfaces; our vision unconsciously reflects that.
My question is, how, and to what extent, does the privileging of portrait-format images change the way we actually see the world?
