I've read opinions that this is a great photo, that it will become iconic. If it does, it's because of what's on the monitor they're all looking at, not because of the picture which is mediocre. Its context makes it interesting. That's true of many PJ shots, but in this case, its context will elevate its significance.
Having said that, I think the photograph captured the tenseness of the event perfectly, Obama leaning forward and Clinton with her hand over her face.
Clinton was later quoted as saying she was suppressing a cough. (Whether you believe that depends on what her definition of suppressing is ... but it definitely changes the shot dramatically).
I agree, it will become iconic. And it absolutely doesn´t matter if this is a good photograph or not, thinking of composition, exposure or whatever, absolutely unimportant.
What makes it important and iconic is the fact that this is the first example of Washington´s new communications strategy, not showing the dirty reality of this "war against terror", violence, blood and the actual killing, but showing the government "at work", doing their part of the job in this "war against terror". Very smart move!
We don´t see soldiers killing Osama (what many expected to see), but we see those responsible for the killing watching the action on a monitor and we see the reactions in their faces. What is actually going on is all up to the imagination of the viewer.
Can´t remember now who said it, but this seems to be a very common element of ancient Greek theatre performances; parts of the plot that could not be shown on stage were shown by showing the reactions of people that could "see" what was going on by looking over a wall. Really would like to know what educated mind decided to come up with this old idea again; once more, very smart move!
The expressions in the faces: Clinton seems to be an exception here; to me it looks as if she is really shocked seeing what is going on, what "Let´s kill Osama" actually means. Might be her reaction is not what a majority like to see and that this is the reason why some obviously preferred not to have her in this image.
Most of the others just look interested, while Obama really looks very tense and concentrated; being the boss he will be in trouble more than all the others when this mission fails.
