Sometimes I seem to miss th obvious point that most people take from a photograph. For instance, I didn't get all that worked up over the Elian Gonzalez photo were he had been hidden in a closet and the SWAT officer was removing him. (I can't seem to find a link to the photo in question, if anyone has a link, please drop me a line) Much was made of the picture in that it supposedly revealed the jack boot of government action trampling on the dream of freedom. Aside from that whole business being a mess from the get-go, I just didn't see that interpretation. The officer had one hand off the weapon, and the barrel was not pointed in the same direction as the officer was looking. If anything, that was as non-threatening as that officer could be, given the body armor.
I am coming off the same type of situation with respect to the photo of President Bush and Ashley. The detail that really gets to me are President Bush's eyes and expression. His eyes are focused on the camera, and his expression reads to me that "this would make a great photo" was not entirely absent from his mind. All told, I don't think that that one photo is the political slam dunk for Bush that a lot of people feel it to be.
As a whole, I tend to be leery of photographs as opposed to video. I think it stems from the fact that I don't think that I photograph well at all. Hence why I don't have one posted here. A photo is just one split instant, image without the context of time. Too much can be read into the vacancy.
