In this photo the photographer has set President Eisenhower with one hand on his hip while leaning against an object to show he's an interactive man. He is also given the appearance of success by the clothing the photographer has placed on him. He also gives off the clear impression that he is a likable guy by the smile on his face. It is no coincidence you can only focussing on him, the photographer has made it that way for a reason. By making the photo a close up you can only focus on who is in the close - up. And the city background shows he's a man who works in the city who is buisy often.
The lighting in this photo does come from an angle making him look serious but also in a way trustworthy and almost like he has secrets. More of so the photographer did this to make him look mysterious and professional. To me this is a convincing photo of President Eisenhower because it shows a serious but fun business man who is successful at what he does.
