Blur (photographic effect)
Blur, in fine art photography, refers to various photographic techniques utilizing blur effects - whether from camera movement, a moving subject, or a deliberate manipulation of focus. While early photography emphasized technical precision and sharpness, photographers since the mid-19th century have adopted blur as an artistic technique. Blur effects were utilized by several major photographic movements including pictorialism, Italian Futurism, and contemporary photography, to enable the capture of movement and various aesthetic effects.
