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.
No manufacturer reciprocity data found; test or bracket long exposures.
