The photo bulbs are balanced to match tungsten film. Pro400 Kodak, is that 
a tungsten negative film? Or daylight film? As long as it's negative, you 
really don't need to filter. When they say reduce speed with filtration is 
applied, they are talking about using a hand-held meter that doesn't see 
through the filter.

When I Photoshop a picture taken in tungsten light (balanced and 
non-balanced - the latter much more often) I add blue, add green, then 
tweak the cyan. I get pretty good results that way. A lab can do the same 
in conventional printing.
