What term is used to define the area of a photograph that will be in acceptable focus?

1. Sharpness

2. Depth of field

3. Focus range

4. Field of vision

The correct answer is: Depth of field

The correct term that defines the area of a photograph that will be in acceptable focus is "Depth of Field." This concept refers to the zone within a photo that appears sharp and in focus while other areas may be blurred. Depth of field is influenced by several factors, including the aperture setting, the focal length of the lens, and the distance from the subject. By adjusting these elements, a photographer can control how much of the scene is rendered sharply. While sharpness refers to the clarity and detail of the image overall, it does not specifically define the extent of focus. "Focus range" is not a commonly used term in photography, and "field of vision" relates more to the angle of view or what can be captured in a frame rather than the focus characteristics. Understanding depth of field is crucial for photographers to achieve the desired artistic effects and compositional interests in their images.
