The following photo montage is from The Atlantic https://www.theatlantic.com/photo/2017/02/refugees-fleeing-into-canada-from-the-us/516993/. This photo essay is about refugees finding a safe place to live. The formal elements help because it is a story of refugees and the visuals show them in snow which brings the viewer to an emotional state. The characters are probably scared and cold. As you meet the characters, especially the mother and children again, the viewer has an emotional response because they are children. The story invokes empathy.
The shots in the series vary. The first shot establishes the setting because there is a taxi on road near the border and the Canadian Mounted Police are waiting for the refugees. The journalist sets the scene right from the start. As the story continues the journalist uses over the shoulder shots when the refugees are walking toward the police car. One photo is an environmental wide shot because it shows the border marker which helps tell the story. Another photo with a big impact is a close up of a man that drops to his knees and begs for asylum. All of the captions work in the story because they explain what the photo is about and who is in the photo. In fact, one photo caption cites a quote from a man that expresses his fear. There are several photos of the man but the most striking photo is when the shot is of the man dropping to his knees. That photo evokes emotion and perhaps motivation to the viewer to actually do something about it. The pacing of the story allows the reader to see the recent events in Canada and highlights the huge amount of people that now cross the border. The journalist uses the first image to set the scene with the Canadian Mounted Police waiting at the border when the taxi pulls up with refugees. The journalist chooses the last scene of the Canadian Mounted Police waiting at the border to foreshadow that the refugee problem will continue.
