Batch-to-batch consistency and stability in storage are attractions of the films from the major manufacturers, but if you happen to like the look of Foma or Efke, it is worth testing, and it can be as simple as comparing the first sheet from the new batch with the last sheet from the old batch, two sides of the same holder, exposed one after the other and processed together. I was surprised once when I found two batches of Fortepan 400 about a half stop apart (probably due to storage conditions, since they were from two different distributors), but then it occurred to me that if I was going to use a film made with 1950s technology, I'd also have to follow the same testing procedures that photographers concerned about consistency would use in that era as well.
Anyway, that's off topic, but the point is that testing doesn't have to be that complicated, and one can learn a few things in the process that will save time and effort later.
From Kodak's website, new technical information on their films. Looking forward to trying it in larger sheet film sizes; and, with the dollar being so low, it's cost should be very competitive to European films.
What David says above is going to become more true and the necessary testing will become more important as time goes on. Storage, shelf life and batch to batch variations of films and papers made by the older methods are becoming significant factors as people buy more economy films.
For those of us who have calibrated exposure and development based upon film curves and densitometer work the new film will eventually mean repeating our film tests again for both sheet and roll film. One can only hope the effort will be worth it....Obviously Ilford can become one's choice if one wishes NOT to have to recalibrate everything. Nothing "wrong" with Delta and HP5, but if one wants to use ready loads in the field it's either Fuji or Kodak. We'll be waiting for reviews from our talented and sharing members.
If this is a veiled poke at Kodak... it's time to give it a rest. The Perez anger is old and most of us are ready to move on. Sure some people are still mad at Kodak for hiring a moron to run the company. Others are still angry that Kodak quit the paper industry, still others are angry about HIE. The rest of us realize that there's more important stuff in this life to get bent about. Sheesh, isn't it enough that Kodak is still developing new film technoloy?
Besides, Edwin's comment doesn't make sense anyway.
