The beach picture at the very top used models and was taken on a soundstage. Prager spares no expense to get the photos she wants. I read that she used 150 models for one of her shoots.
Maybe she can afford to do that because her pictures are reproduced large and are sold alongside paintings in fine art galleries.
I'm not normally a fan of Bleak Minimalism (my term for it) but I'll make an exception for Prager.
