Capitalism is good when it works in your favour :P
Portraiture could work just fine for Getty. There's no legal issues for you if your models sign a release. That's the point. If you shoot to a concept or theme with people you'll probably do better than I would. I hardly ever have people in my photos and businesses love showing real people.

Getty has removed their RM images and are just going with RF. All my photos are RF anyway so it doesn't affect me. Maybe all the people looking for RM images will take a closer look at mine now.
