Effect
Motion Temporal
Blend across recent frames for trails and temporal smearing.
Temporal effects blend across recent frames so motion leaves trails. Film and video do this whenever shutter or persistence mixes time; dance photography and light painting celebrate it.
Trail length turns everyday movement into calligraphy.
