Topic: Alien Lights -- but no lights??

I am filming a section of my film in a (very) remote area -- on some hills.
As the alien ship (CG) passes over the people on the hill, I wanted to cover them in searchlight type beams. They may need to be different colours, whatever.
As I cannot get these, or power them on location - how would you suggest adding this effect in Post??

There are some plug-ins for After Effects that will allow you to simulate spotlights shining on certain parts of a frame. Boris F/X Pro (the expensive version) is the only name I know off the top of my head.One issue....the highlights these plug-ins create won't light up details that weren't present in the original shot. So, if you're shooting a night shot and the subjects are poorly lit to start, the effect won't come out well. You'd have to film a day shot, apply filters to give it a night look, and then create the spotlight effect. I think this is a pretty challenging thing to pull off in post with affordable tools. Maybe you can re-storyboard so you can get the colored lights by something simpler, like plain old flashlights. Or switch to a wider shot where you can create a low-detailed CG actors and control the lighting. |

do you have access to one of those handheld searchlight/spotlight things? they make handheld rechargable versions that cost like $20-40 dollars (us) you could get up somewhere perhaps a tree or hill, and shine it down on the actors, with some filters it could look good.later

Yes, I'll try hiering a Portable Spot... But I don't thing I could get more than one... I'd imagined the scene with quite a few light.s |

How about this: I know my PhotoShop came with a filter called "Lighting Effects".
Does this come standard with PS, or did I get it seperate, I cant remember,?
If so, can I use Photoshop filters in Premiere? (you see, premiere is not on the computer I have at home) |

Try mounting auto spotlights in small boxes (for safety) and powering them from a car battery. You can use cellophane present wrapping for 'gels' to color the lights.[This message has been edited by cdolsen (edited 12-19-2000).] |

I have a perfect way to "simulate" the light if the actors are standing still if not you will need to do alot of rotoscoping and masking but if you can handle that its ok also if the lights are moving it poses a challenge aswell...
Anyway ill try, umm you already should have and idea of how a light acts so all you have to do is make a mask and like blur the edges so it will look like the light is interacting with the scene so if you are masking light on a guys face make a mask only half of his head follow the contours of his head and blur the edges so that over all the mask takes up 3/4 of the guys head then i had the idea of using the mask to mix the footage with footage previously altered with the brightness contrast filter...heh i hope this helps caus ei just thought of it on the spot and then when i thought it out more it turned out to be not such a full proof operation. |

Yer, that's kind of like what the Lighting effects plugin does for Photoshop... Can you use this in Premiere? |
