This photograph is called the Woman with eyeliner which was taken by Diane Arbus. This photograph represents an example of a narrow depth of field photograph because the photographer focuses the lens of the camera on a focal point or focus point. In this case, the woman is the focus point due to the fact that her face is clear and the rest of her body and background is blurry or not in focus. With this tactic, the image becomes more meaningful. With the woman’s face being the focus point, she becomes something way more powerful than just a woman wearing eyeliner. She is the subject of the photograph and her presence needs to be felt through the photo and it is felt due to the short depth of field. It adds so much to the composition of the photograph. The viewers’ eyes go directly to the woman’s face, more specifically, her eyes. Then the viewer zooms out, and nothing can be visibly made out due to the blurriness of the background which adds intensity and emotion. This composition in combination with the narrow depth of field draws the viewer into a deeper perspective which adds strength and meaning to the photograph.

This photograph is called the Stream, Sea, Clouds, Rodeo Lagoon, California which was taken by Ansel Easton Adams in 1962. This represents an example of a large depth of field photograph due to the way in which the focus point is the whole photo. In other words, the entire photo or landscape that was captured is in focus. The photographer purposely made his focus point the whole field. The landscape is all one together and it needs to be represented as that and by focusing on it from the clouds to the sand in one shot creates an extraordinary and interesting photograph. This allows for the photo to bring the viewer in by starting at the bottom with the stream on the sand and then flowing to the ocean and then up to the clouds. The whole composition is in focus which creates a way more meaningful photograph. The shadows on the water, sand and clouds add more depth and layers to the composition as well. The choice to take this photo in a large depth of field was smart because that allowed the composition to be stronger which makes the photograph more powerful to the viewer.
These are good examples of the use of short and long depth of field and show your understanding of how focus is used in both. Good choices.
