Brandon Adams Posted May 16, 2005 Share Posted May 16, 2005 I'm trying to figure out how the light blur effect is done. If anyone has any insight, I'd greatly appreciate it. What I'm talking about can be seen in BMW Film's "Beat the Devil" http://usa.bmwfilms.com/clap.asp?template=...lm=beatthedevil And Claudio Miranda's commercials http://www.claudiomiranda.com/alpinemute.html http://www.claudiomiranda.com/MotorolaMoto001.html http://www.claudiomiranda.com/AmericanAirlines001.html Thanks, -Brandon Link to comment Share on other sites More sharing options...
Premium Member David Mullen ASC Posted May 16, 2005 Premium Member Share Posted May 16, 2005 Different things going on in these spots. Some shots in Tony Scott's short undercrank the camera (like to 6 fps) to increase exposure time and motion blur. The Alpine Mute spot was shot with anamorphic lenses, which get you that blue line flaring from bright lights. The Motorola spot seemed to have used a mistimed shutter to get bright highlights to streak, but since these are normally vertical streaks, I believe he turned the camera sideways, shot with the mistimed shutter, and then rotated the image back 90 degrees to a normal orientation in post (or shot with a sideways movement format like 8-perf 35mm VistaVision but I doubt it.)

Brandon Adams Posted May 16, 2005 Author Share Posted May 16, 2005 Thanks for the response David. Does mistimed shutter mean the shutter is opening as the film is advancing? How does this not cause the entire image to be blurred? Is it properly exposed at some point before the mistimed shutter? Link to comment Share on other sites More sharing options...

Brandon Adams Posted May 17, 2005 Author Share Posted May 17, 2005 Can a camera be temporarily modified with a mistimed shutter? Is it something that must be done by a professional? Sorry to keep asking the questions, can you point me in any direction to learn more about it? Link to comment Share on other sites More sharing options...

Sorry to keep asking the questions, can you point me in any direction to learn more about it? <{POST_SNAPBACK}> Yes, it's something a camera tech should do for you. I've heard that some of the newest cameras can be programmed for a mistimed shutter, but I'm not sure. The only time I've gotten that effect was by accident on my first feature, using a crappy 35mm Ultracam. Learned the hard way what the effect was, years before "Saving Private Ryan" did it...

Rolfe Klement Posted May 17, 2005 Share Posted May 17, 2005 Some of Claudio's work is very VFX heavy and he might have been able to use anbother approach. There are some sparks (Plugins) for inferno from Genarts that can track light sources and create these FX - there is even an anamorphic blue one :) Check out the images near the bottom of the page at http://www.genarts.com So if you have VFX budget you can do some of it in post - it is slightly more controlable thanks Rolfe Link to comment Share on other sites More sharing options...
