Daylight / Tungsten

[Chris Burg]

Knowing that the white balance can be done in post - Does the R1 delivers the same quality of images in tungsten than in daylight?

I would like to know because I have a set of Tiffen 85B ND Filters here… Can I use this Filters without of quality loss or should I look for plain ND Filters?

Thanks for your help

Changing the white balance does gain the underexposed Rgb Channels and this will always make the quality worse. There's nothing magic to white balance. Say if you want to rebalance a tungsten shot and therefore set it to let's say 3200 you're just pulling up the blue channel that was underexposed in the first step and thereby not recorded in full bit depth so you will also pull up noise.
Red one has a native 5000K sensor. Try always to work around that point by gelling the lights or using filters fir best results. You will want to feed each channel with as much information as possible..

Thanks for your reply …
You say “Red one has a native 5000K sensor”. Does this mean even If I do a rebalance to 3200k before I make a shoot (not in post) there is a loss in quality? This would mean all shoots where I can’t use daylight are not as brilliant? Hmm…

[Kim Frank]

Yes that's right.
If you set the white balance while shooting or afterwords doesn't matter. It's the same thing as all this just metadata and not baked in the footage.
But with every Camera white balnancing is nothing magic! Every camera has a native setting and it will have to gain the underexposed channels to rebalance.
The new colour science fixed the noise ratio in the blue channel (I heard by mixing green into the blue channel) but it's still a 5000K sensor and will give best results arond that tempreture of light.

Bingo…


thanks

but what can i do, if i HAVE to shoot tungsten lights like practicals in a living room f.e.

??

is it better to don´t touch the balance while shooting and fix it in post ??

An 80A would be my choice but loosing 2 stops ....

You can use an 80c filter and lose less light, though you of course are correcting it less to daylight. Honestly though, so Long as you dont underexpose and then try to bring it up in post, shooting tungsten shouldn't be an issue.



Thats with a 3200k photoflood, dimmed down a bit, so maybe 3000k or so? And the fill is from a daylight source, but gelled with tons of CTO and some CTS to boot. A very warm image. If I tried to make it cool in post, it might look noisy, but as is it looks very clean. This is without any filtration (other than a 1/8 promist, of course.)

thanks andrew

do i understand right ??

this photo was shot on 3200º ??

looks great

have you seen it in theater ?

[PatC]

That tree rocks!

[Andrew Wilding]

While shooting, the camera was set around 3800 if I remember right - What I set the white balance to in post I cant recall at the moment, but somewhere around 3200 no doubt. No, I have not seen it projected...
