And on the other hand pornography sometimes have beautiful models, but the beauty is ruined by strained, unnatural poses which makes the model look like a lump of flesh rather than a creature of grace.
In those cases, even when you do get a good picture, it can be at the expense of the model and her beauty.
But most of this is a retrofit, an overlap from either fine art or soft erotica. We tend to forget that pornography/erotica only a few decades ago was illegal all over the world, so people did what they could get away with, which then of course often looked like simple nudes.
The proof is that pin-ups, "cheesecake" and so on basically disappeared once porn was legalized.
And it has taken a few decades of legal porn for enough people to get fed up with it, and being open now to the possibility of Simple Nudes, without the focus on sex.
If you are one of the people with the perceptions necessary to appreciate these things, you have come to the right place.
