What does "quality of blur" refer to?

The term "quality of blur" specifically refers to the intensity or level of blurriness applied to an image or scene. This encompasses how pronounced the blur effect is; a higher intensity will result in a greater loss of detail and sharpness, leading to a more pronounced blur. Conversely, a lower intensity will create a subtler effect, preserving more detail in the image while still introducing some degree of blur.

Understanding the quality of blur is crucial in visual storytelling because it affects the viewer's perception of depth, focus, and overall visual aesthetic. The intensity of the blur can be strategically employed to draw attention to certain elements within a scene or to create a mood that fits the narrative.
