Short video showing our 2mm Clear Rota-Streak with white light LED headlamp and multi-colored LED finger lights. Rotation of the Rota-Streak was done by hand. A wireless remote motor would be smoother and more controllable.
This 2mm streak is our strongest streak filter. Adding more light on the subject would make the streaks relatively weaker.
We also make more subtle streak filters with 4mm and 6mm rod lens spacing inside the filter.
