A portrait is a portrait if it captures a person or people. It should capture what there is and who the person is. A portrait should capture the person’s identity.
Selfies are portraits. It’s more of a self-introduction portrait. It tells a person about you what you want to show them.
A portrait should include a person or multiple people. It’s not a portrait if there’s not a person there.
A good portrait expresses who the person or people are. A good portrait, in my mind, is not heavily edited. It’s more natural in what you see.
I think it depends on what small detail. isn’t a portrait supposed to capture the human so maybe only small details of very human things like our eyes.
I think the line is when it stops showing the identity of the person and stops looking human.
I think it’s hard, but it depends on the person. Some people’s entire life is all 1 thing, so maybe you can, but I think it would be hard for most people since most people are very complex and unique.
It can be multiple images exspecailly if its ones where it slowly zooms in.
