Characteristics
Reciprocity failure
No official data available. The manufacturer hasn't published reciprocity specifications for this film.
For long exposures, try starting with a 1.3 exponent (t' = t1.3) as a baseline and bracket your shots. This is a reasonable middle ground that works for many films.
Kodak E-4000 (Aug 2018): no speed or colour compensation from 1/10,000 s to 10 s. At 120 s Kodak says to add CC10R filtration and gives no exposure correction, so none is given here. Make tests for longer exposures.
