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?

Because models are trained on images that are usually edited in post-production with this aesthetic.

Mostly highlights down, shadows and clarity up. I often needs to edit it back to have realistic looking lights on scene.

Also "--s" 0 helps with generating more realistic images.

Sorry to ask a dumb question, but… is this in the prompt for a larger provider like ChatGPT (DALL-E) or are you using your own?

No DALL-E doesn't take flags like this. This looks like the stylize parameter used in midjourney.

Thanks. I assume this is being run as a private service then and not a publicly available tool in a marketplace.
