flare-like blue streaks
Posted 12 July 2007 - 05:33 PM
I'm curious, is this a filter creating this effect? It's a bit overused now (Transformers, et al), but I'm still curious how to do it.
On a side note: I was doing some scouting with a friend's cheap digital still camera, and I noticed that right before the picture was being taken, the lights in the frame made a vertical streak. I'm assuming it has something to do with phasing and the shutter (a la "The Limey"). Can this be duplicated for motion picture (film or digital)?

The vertical streaks you've noticed are two different things. In a digital still camera, it's the chip "overlaoading" with too much collected charge which then gets dissipated across adjacent pixels above and below. This is known as vertical smear. In The Limey the effect was created by throwing the camera's shutter and pulldown out of phase so that the film is actually being advanced to the next frame while the shutter is still open.

The blue flare is from typical of anamorphic lenses. The well known blue flare is usually from Panavision Primo anamorphics.
There are filters available to create this effect, streak filters may be do the trick, but they will not be blue, they will be the color of the light source.
I think someone may have made a filter that specifically recreates the effect you are after, but I can not remember off the top of my head. For some reason I think it was Hawk Anamorphics that made the filter (don't quote me on that though).
Ahh Michael beat me to it

I had a lot of time for Vantage before that........ I'll be a little more careful in future.
