Digital BW, The Print

The color temp of the lights is important but is only one of the 
issues that affect the color cast when shooting tungsten balanced 
slide film.

If you read all of the tiny print on the spec sheet that comes with 
the film you will see that, for shutter speeds under 1 second a CC 
filter is suggested,often it is a green filter.

I do color critical work in my studio to reproduce art work and this 
is my procedure.

I buy a large quantity of 6118 Tungsten balanced film of the same 
emulsion number, I shoot a test frame of a Kodak gray card and get 
densitomitry readings from my lab. All exposures are always done at a 
one second exposure.

the numbers from the lab indicate two important bits of info, one is a CC
filterpac that will be required for all subsequent exposures, and the 
density indicated what the true studio ISO speed of the film is.

T64 is a great film but takes a little extra care to get it right.
