Annie Leibovits is a world renown American photographer.  Her photographes are mostly of celebrities like John Lennon and Brad Pitt.  When Annie was first starting with Rolling Stone, her photographs were very genuine because she spent days and weeks on end with the people she was photographing.  The celebrities even said after that  they felt that Annie was a part of the group and did not think twice when she was taking their pictures.  And that is why her earlier photographs look and feel more natural than her newer photograps.

During the 1980's, Annie shifted course and started focusing on more of the staged shots of celebrities.  To me, these photos were the ones that really brought out the personality of both Annie and of the celebrity themselves.  Annie really knows how to capture the essence of the person she is photographing.

James Natchway's photographs are the complete opposite of Annie's photographs.  Natchway's photographs are of war, poverty and the bad sides of the world.  And that is the biggest difference between the two photographers.  In Annie, you tend to see the good side and with Natchway you see the bad.  Natchway is like Annie in that he becomes a part of the group he is trying to photograph.  He's not trying to rush things and be noticed by the people he's photographing.  Natchway is trying to give his subjects the respect they deserve.  And so the feelings that Natchway captures in his photographs are very genuine and very in the moment and real.

  The one common thing that both Annie and Natchway share though, is they have both dedicated their lives to thier work.  They really care about what they are trying to do and they let thier photographs do all the talking.
