Portra 160 Colour Casts

[steveo_mcg]

Guys, any one know if Portra develops any annoying colour casts at longer exposures, say 15-30 seconds?

I believe @Woodsy has done some exposures of that sort of time with Portra, he should be able to inform you.

I have a box of 5x120 rolls of that on my shelf

I would be interested in long results with it also

Good to hear

Never tried it myself but saw this elsewhere ...."it goes cyan after about 30s or so, enough that it makes "proper" color correction very difficult, in both optical printing AND drum scanning".

Also, just found this

Sadly not I'm afraid. I've shot a box of this stuff, but never at exposures this long before. Wonderful film either way though

Cheers guys, I guess I'll have to do it the old fashioned way.

How bad is the blue cast? Any chance you can post an example?

Im going to pop a roll of the 160 in my pentax 645N this weekend and try it myself but not up to long exposures maybe just a few seconds.
