With Fuji's introduction of their new Eterna series, they have claimed a reduction of "noise" in the blue level. Anyone please correct me if I'm wrong. If that is the case I would imagine that would be an important consideration if one was to shoot with Tungsten film in an outdoor situation without using an 85 filter for correction with the desired look being a monochromatic blue. Would the "noise" but that much more apparent in Kodak stocks vs. Fuji's? Yes, test, test, test, however I was just wondering if anyone has had an experience or an opinion about this matter.

I believe the reduction in "noise" is relative to their previous product. Don't confuse "noise" with graininess --- in a transfer of a color negative, some telecines exhibit more electronic "noise" in the highlight areas, mostly as a function of the blue density. By all means test, but I think the Kodak VISION2 films will compare favorably.

Noise is an electronic artifact. The Eterna line is finer grained than previously, but they may be referring to the fact that they changed the density of the orange color mask to improve noise in scanning / telecine.

Anyway, a daylight-balanced film will still have a relatively slower-speed (thus finer-grained) blue layer compared to a tungsten film of the same ASA. So probably Eterna 250D will have slightly less grainy blues than Eterna 250T.
