See sample video http://www.youtube.com/watch?v=sVRCaRs-BYw&feature=player_embedded
What I want to know is how I can get this quality but without the lights making a star shape or halo, but still get the same high quality image of the other stuff that we do want to see (eg. road markings, cars, buildings etc)
Have you tried using a circular polarizing filter? I would think that ought to do the trick.
1) clean your lens and check for scratches.
2) set your aperture wide open manually if you can.
3) a polarizer or nd filter may force the aperture wide open if you cannot set it manually.
4) adjust your exposure to reduce the intensity of the highlights so they don’t overxpose…
failing that, if you can’t beat em, join em. Try placeing an actual starburst filter on your lens to make the effect look more deliberate, or try adding black cardboard discs infront of your lens that have little cut out shapes to create interesting Out of focus highlights (or Bokeh) effects…
Looks like this is being shot frominside the car.
Make sure the windshield is very clean both inside and out (this looked like wiper blade marks to me). Also make sure your camera lens and any filters you are using are very clean as well. Use a bright light source and shine it at an angle on any of these surfaces when inspecting them increases your chance to see any smudges and such that need cleaning.
Craftersoflight… I did not actually review the video, but you are very right in mentioning the windsheild/window if it is very scratched up it too will create starbursts or smears if dirty… and the solution may wind up being…. mounting the camera outside the vehicle… a good cleaning with lemon pledge on the inside and outside of the windsheild may help fill in the tinier cracks…. for the shoot….
Hey guys, thanks for all the advice. I’ll have to shop around for filters and work out how to manually set the exposure on the camera. If I still have troubles I guess Lemon Pledge is worth a try, but hey… that sounds like work! Anyway thank you for all those suggestions.
