Good point. Most magazines get all the rights. I knew a writer years ago who would only sell first North American rights - but that's unusual. It seems Atlantic Monthly would have a standard contract. You might be on to something here.
I think some photographers of note get to negotiate that into their contracts. I have a funny story about that. When I was working at SHOWTIME, we were airing the “Lost Episodes of the Honeymooners.” It was a big thing. We were doing an interview with Jackie Gleason to be done at his home in Connecticut..or something. Well, I wanted to play the bigshot and hired an old high-school friend I had a bit of a crush on... He was an up and coming photographer and I just wanted to show off. So I hired him and let him have the rights to the shoot. Turns out this was the last interview and photo shoot Gleason ever did as he died soon after... and this guy still owns the rights! Oh well...
