Depth of Field | Crabapple Blossoms f4 An f-stop set to f4 produce a little deeper DoF than f2.8. Now, the entire cluster of flowers in the foreground are in sharp focus and the background out of focus flowers have a bit more definition with deeper color. In portrait images, the entire head and shoulders is in focus. In wildlife photos, f4 still isolates the entire head and shoulder. In insect images, the insect and much of its surroundings are in focus. For the whole story with all images, see Depth of Field | a 7 Image Story.
