Here's my results thus far:
NEW Portra 160NC, 4x5 Sheets
Film Speed:
EI:160 looks right on. I shot a bracket using EI:80 to EI:160, suspecting the film to be rated optimistically. I was wrong. Box speed works great. This is based on spot meter Zone III placement of "average dark material."
Reciprocity Data:
To 1 Sec: No Adjustment
4 Sec: +0.5 Stop
15 Sec: +1 Stop
30 Sec: +1.5 Stop
1 Min: +2 Stops
2 Min: Not Recommended
Other Observations:
The film looks nice and sharp, and with very fine grain.
I see no major color anomalies with the GMB Color Checker. The lower/softer contrast is apparent when comparisons are made.
Conclusion?
While it appears to be a very nice looking film, it seems to suffer from reciprocity much more than it's predecessor. Why, Kodak? WHY?
