questions about tummy photos

I posted this under 2 topics because I am not sure where it belongs.

I am curious about before & after tummy photos and all tummy photos in general.
Are the subjects in the photos flexing or holding in their tummies for the photo or is that how they look all the time?

Maybe it's because I've had 2 babies but no matter no small I get my tummy never looks as tight as the photos I see.
The reason I'm asking it so I don't develop unrealistic expectations thinking that my tummy could look that tight all the time if I just work harder in the gym/kitchen without holding/flexing. There's a big difference when I hold my tummy in vs letting it "all hang out", I've asked a few people and no one seems to know what I'm talking about. Thx
