Comet Light

[Graham Bernard]

First thoughts would be:

1/- Start with a Green field captured in daylight.

2/- Use any of the Luminance FXs and Chroma to desaturation and restrict their effect to the outside of a Mask of the shape of the descending Comet.

3/- Track and Sync the Mask across the Green field.

Just a quick and dirty 5 minute attempt, but is it something like this you are explaining. Obviously needs more time to make a proper version but it is using the technique as described by Graham

Thanks guys but like I said, field pic is at night, there’s no day version.
But I understand you guys point, is there a plugin that could illuminate that night pic wherever I want?
This way I could make that plugin illumination follow commet 😉

You have a dark field, then maybe just a tiny lift in Luma and Chroma will do it. All the Mask stuff would be the same. Wanna give us a ScreenGrab//Still of the Field.

[Joao Souza] “is there a plugin that could illuminate that night pic wherever I want?”

Yes. And to follow use the Mask in Pan Crop.

Bye!

Yeah but how could I do that without a day version of the field?
Probably impossible because no plugin could illuminate something that doesn’t exist LOL
Ok let’s assume I have both night and day versions, do I have to “draw” comet shape with mask?
If yes it means its borders will be hard meaning not like light but like a wall, can I make softer edges letting “light” scapes a little like a blur effect and not ending so hard?

Umm so you want a night scene without any Green field….? You said ” Imagine a photo of a beauitiful green field, it’s night and a fire comet flies by close to the ground, as it’s on fire and it’s night how could I make it illuminate the area it flies over” so do I think you want green grass but not to see it as it is night time and only show when the comet goes over ( as in the quick demo https://www.dropbox.com/s/gndm72m7wrtpbu2/night%20comet.wmv) Maybe you can do a PIC file to show what you need……. In the Demo the Green field is dark unless lit up by the comet…Maybe others on here can enlighten the question a bit as clearly I miss understand you..

You did it right,I said “imagine a green field AT NIGHT, or a beach whatever, it’s night so it’s dark maybe with a full blue moon, a comet flies by and its light illuminates where it passes, illuminate doesn’t mean whatever is below will become day.Your video is right 😉
