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-2468: designed for exposure times of 1/1,000 s to 120 s with tungsten illumination; long exposure has minimal effect on colour balance and contrast.
Development times
Portra 100T is developed in standard C-41 chemistry: 3:15 in the colour developer at 37.8°C / 100°F, the same as every other C-41 film. Blix and stabiliser times come from your kit, and pushing typically adds about 30% per stop.
