Portra 160 Reciprocity?

[l2oBiN]

Has anyone tested the reciprocity of the new 160? I would like to know the characteristics in the 1second to 16minutes range.

I might be able to answer this tomorrow - I have some negatives to scan that were shot on Portra 160, exposures from 2 seconds to 2 minutes. The negatives themselves look okay, and I barely adjusted for reciprocity, but I won't know for sure until tomorrow.

Would like to hear your results =}

There are some results posted on the Fuji website. Take a look at the technical specifications pdf on their website.

For Kodak Portra?

Portra 400 reciprocity would also be good to know!

I did some extremely informal (i.e. "do the negs look OK", no densitometer involved) testing of P160 (in 120) out to about 4 minutes. Seems that about half a stop was good enough, i.e. it has excellent reciprocity, nearly as good as Acros.

I was curious about this, as well. I shot a few sheets last week with exposures ranging from a couple of seconds out to 30 seconds. It's good to know I'll be in the ball park.

Thanks,

Now PB, that assumes your metering was in the ballpark.
