4 layer color neg films.
There is something that all of you are failing to take into account.
If the negative film in question is of the newer 4 layer color neg films,
it will correct for the tungsten light on it's own. That's what it's
designed to do. The days of getting that warm fireplace glow,
are now out without Photoshop. Run a test for yourself...
I know that the Fuji 1600 was & I think that both Kodak &
Fuji 800 Pro films were, last time I checked.
I just did a Nude Fireplace Shoot, last year, with available light,
to get that warm glow & the images, ( even the fire ),
were neutral...
