Why do people not smile properly if theyre supposed to be happy with their partners in pictures?

I just couldn't imagine looking miserable if im supposed to be happy

some people are just naturally awkward like that... in pictures

Natural smiles tend to not appear for random photos that are staged.

Kinda of hard to have a natural smile for randomly staged photo's.

[Monalisa77]

It's fine for a lot, just some people can't even actors can't

[Liketotry]

They look like their smile is pasted on, not a natural look
