day > night

[Tagger]

it's about time i made a post in here, so here it goes :P
i have 2 questions.

can anybody give me some tips and pointers on making footage filmed in daylight (filmed on a spring day like we have a lot today in good old western europe) look like good night footage (in full moon lighting)

is there a script/conversion trick to change 3200K footage to 5600K, faking a CTB filter or something

ps: I'm using shake 2.5

thx,
Tagger

Ive done one day-to-night-conversion so I'm by no means any guru, but the tips I've learned from others include these ones:

* Contrast is generally higher during night than day
* Moonlight tends to give a blue tint for the scene
* If you've got lots of white clouds you are recommended to mask them out and change (else they'll look very fake)

Also, the saturation will need dropping hugely.... In low light, our eyes use the rods more than the cones, and the rods don't see colour.

Thanks Hugh, I forgot that step. That's probably the most important one.

Haha... love your t-shirt Rikard! :)

Thanks :)

You can see it (and me) "in action" on this image: http://bos.hack.org/tmp/compositor.jpg

I won it at a minor matte-contest over at www.creativecow.net some months ago. It's possible to buy the tshirt online from the company I won it from:

Hello there Tagger...

[Tagger]

o no, it's mister forster ! hey BK, you a shake user? (for potential future irc-bugging purposes)

[Hugh]

Hey tagger - good to see you here!

Just remember I posted a WiP of a Day To Night that I did a while back.... I'll see if I can track down the thread for you...

[Hugh]

Here it is:

Looking at it, I realise that I did a lot more work on it after this... But it's certainly a start there....

If I get some time tonight, I might just post some shots of how that one looks now...

[Tagger]

thanks a lot :) exacly the kinde info i was looking for

If I remember correctly Hugh, the final comp on your reel was shifted even futher to dark?

...for some reason I still giggle when watching your reel, it must be the music and the guy doing the flip hehe. :guitarman

[Hugh]

hehe

Good point, though - tagger, if you want to see the (pretty much) final shot, it's on my reel, which you can grab from here (http://www.brokenpipefilms.com/hugh/hugh_showreel_compositing_03-11-03.mpg)

[Tagger]

nice reel :)
got another question, what's the best way to mask out a white sky (to put a nightsky in stead) its a real pain to get it out of there especialy cause in some shot's there's a girl with blond hair which makes it even more trickyer
