This is unsurprising. Consider photos of crowds of protesters. They can be framed "just so" to make the group of people fill the whole frame, giving the impression of a large protest, or they can be shot from a greater distance or a different angle, to make it seem like a small gang of losers.
In independent photojournalism, I expect the bias to be the photographer's own. In bigger news organizations, the bias is whatever the editor wants. I imagine the editor's bias depends on what he thinks his viewers want to see, because everyone loves to have his prejudice confirmed.
