One key element is authenticity. The photograph must be a true representation of the situation. Lighting also plays a crucial role. Good lighting can enhance the mood and bring out the details in the photo. Also, the photo should have the power to evoke emotions in the viewer. If it can make the viewer feel something, whether it's joy, sadness, or anger, it is more likely to effectively tell the story.
In journalism that uses photography to tell a story, the key elements are multiple. Firstly, the photographer needs to have a good eye for detail. This means noticing small but significant things in the scene that can add depth to the story. Secondly, context is vital. The photo should be able to stand alone but also fit within the overall narrative of the story. Capturing the right moment is also essential. A split - second decision can make a photo go from mediocre to iconic. And finally, the photo should be able to communicate a message clearly without the need for excessive explanation.
