Filter to get irregular streaking


Recommended Posts

Hi,

 

I was biking home today after watching Finding Dory, going uptown on first avenue in Manhattan, and I always love the "effect" I was experiencing, and I often become away of it after going to a movie - where all the streetlights and lightsources bloom and streak - but everything not near the light sources looks not too soft - but the main thing is that the streaks and blooming are totally irregular, some lights have massive streaks, others very little, some in one direction, some in another - is there any filter or other image modifier that can approximate that?

 

Thanks!!

Max

smeared nose grease is great for this effect. you can fine tune the effect by making strokes with the grease to different directions. it works mostly by diffraction so the streak direction is sideways to the stroke direction (just like with fishing line based streak filters, a vertical line makes horizontal streak) . if one filter is not enough you can make another on the other side of the optical flat to save filter trays ^_^
