I don't think so, but I'm not a photographer. And as to the trailing, if you're twirling the blade fast (in the dark, of course) it'll still have the same effect. If you watch someone who knows what they're doing, there are even motion trails in real life. So even if there aren't trails on the single frames of a movie, it 'should' have the same appearance when viewed.
Lol, I like to think 3 years in Haidong Gumdo allows me to say I know what I'm doing, but I mean a trail of the solid white core, not the color itself (which is what happens).
Thanks Ultra, I'm gonna go ahead and test each setting to find a compromise, I'll post the best results, possibly with pics or vids.
