A couple of years ago I bought every remaining 120 roll and 4x5 sheet of the old Velvia 50 on the planet - or so my wife thought anyway. Since then I have been happily working through my stockpile.
I am about to shoot some of the new Velvia 50 for the first time.
I have always exposed the old 50 at ISO 40 - I found that produced fewer underexposures and worked better for various unmentionable post-processing activities that may not be discussed on APUG (ahem).
To experienced users of the new Velvia 50 - what do you think is its "true" ISO - 40 or 50?
NB: I put the word "true" in quotation marks to show that I know these things are subjective and to avoid some of the religious debates that have occasionally arisen on this subject. And please don't say "try it for yourself and make up your own mind" either because I am heading off overseas on Saturday and will not have the chance to run off and process a test roll first.
So for those reasons the informed opinions of my fellow APUGers will be of great interest.
