Hi guys. Ive shot a few car ads and Im just recently wondering how you guys boost down the car's headlights. I usually put ND gels on top of it (cut exactly the shape of the headlights) but the problem is when the car needs to turn off the headlights then you can obviously see the nd gels on top of it.
I guess the only way is to boost down the voltage of the electricity or wattage of the bulb unless your not allowed to touch the car like that. Anyway, maybe any of you have suggestions or tricks on this. Thanks.
Most cars nowadays have lens housings which the bulb fits into. You can romove the entire lens housing, take the bulb out and pour some grey water-based wood stain in the lens housing, swish it around carefully so that it coats the entire front of the lens from the inside, then let it dry and put it back the way it was. You can't leave the headlights on for long as it will start smoking at some point. Test.
Then when you are done, repeat the same process with water to get the stain out and replace. Or if you have to (it's a brand new car), replace the lenses with new ones. They're about $250 each, atleast for a Toyota they are.
