Pushing Portra 100T - Followup

Well, in the absence of conclusive experience, I tried it. Won't be trying
it again.

I tried a two stop push to ISO 400, and the loss of shadow detail was _a
lot_ more than you'd normally expect for a two stop push. Also the grain
looks more like I'd expect from a three stop plus push. The colours aren't
bad though...

Looking at this I expect 100T would be useable with a one stop push, but
probably not worth the bother. Two stops: not recommended.

Oh well, back to high speed daylight film and an 85B next time I need to do
that sort of thing. And it's never a waste of time experimenting...

You can't push film. Underexposure is fatal. Don't even try.

Thanks for sharing the data point. Any scans?

Do it all the time. Great results, both negatives and E-6.

Not yet, and it may be a little while since I have a lot to do before
Christmas, but I may be doing one or two in due course, and can post a link.
