Ask HN: Why are AI generated images so shiny/glossy?

I’ve noticed a lot of the time you can tell an image is AI generated because it has a shiny/glossy lighting look to it.

Has anyone figured out why this is the case?

It’s just the typical aesthetic model used and isn’t inherent to the tech itself. It’s very easy to make AI images in specific art styles, with the result that you can’t tell they’re not real.

This is actually something of a pet peeve of mine - people sharing AI images never use styles other than the generic shiny one, and so places like Reddit.com/r/midjourney are filled with the same exact style of images.

Edit: if you’re looking for other style inspiration ideas, this website is a great resource for Midjourney keywords: https://midlibrary.io/styles

But why is this the prevalent, default AI style across many models? Is it in the training data or is it some bias from the algorithm?

This must have some concrete answer and not just "it is the way it is"

That is a good question. My guess is that their training data was a mix of photorealistic images and historical paintings, and thus the outcome is the cartoony style that looks somewhat realistic but not overly so.

There’s also the possibility that they avoid being too realistic for fear of deepfake scares WRT the underlying tech. And so if you want images that look realistic without being believably “real”, you’ll get something like the default aesthetic of Midjourney.
