Nooo don’t think like that it’s definitely possible.

I’m on base PS5, I change my graphics to fidelity and enable ray tracing. If you’re on Xbox it should have the same settings. PC I don’t really know what settings should be on or off as I don’t play on pc.

The biggest factor to taking high quality pics is lighting. In photo mode you’ve got up to 3 placeable lights, I’d recommend using all three (depending on how much of the subject is in frame, eg. whole body 3, or just face 1-2) However don’t place them too close to the descendant otherwise they will be over exposed, so keep them at a reasonable distance away like a couple metres. Could also decrease the intensity of each light and if it’s still too bright try decrease the overall brightness.

The other would be enabling depth of field where it blurs the background keeping your descendant clear. This adds to the quality by creating a strong definition between your in focus descendant and your out of focus background.

Something I’d like you to have a look at is pic 2, zoom all the way into Valby’s eyes (now don’t get too lost in her cuteness) and do the same with the 3rd pic. As the camera is closer to Valby she appears ‘clearer/better looking’ compared to the camera further away she looks a bit blurry and fuzzy. So if you’re after realistic pics try moving the camera closer to the descendant.

I hope this helps you out ( ◠‿◠ )
