Walter, agree much to ponder.
As for the ice cream, we had a Magnum, which is an ice cream on a stick. About 5 years ago we were in southern Spain on a hiking holiday and we were given Magnum ice creams as part of a promotional thing in a really tiny hill side village. Apparently the Magnum ice cream was 25 years old and the give aways were part of the celebration. Since that give away, we have probably had a few Magnum ice creams on various holidays each year; we don't eat ice cream at home, so it is a real treat when on a holiday.
I would suggest that the Bergger film you may have used in the past, is certainly different to what is available today. The current film, called Bergger Pancro 400 is quite a different film from anything I can remember using. It has two distinct speed coatings, as I understand it, the idea being to hold deep shadow detail as well as light highlights. Other films I know have the same thing and do the same thing, but not, it seems to me, as well as this Bergger film.
It really is a nice film to print, nice to scan as well; which I'm finding out as I scan many of my films these days to share on fora like this one.
As for developer, mature D76 1:1. Mature, means the developer is at least a week old and could be anything up to six months old. Over time I found I seemed to get better negatives from older developer, with the advent of the internet I was able to do some digging and found out that matured D76 did in fact change slightly as it matured, compared to fresh developer. I mix my chemistry from scratch, have been doing that for the last 30+ years. At times I have used developer so fresh I was waiting for it to cool directly from mixng before using. These days I keep a couple of litres in stock, in fact after this morning session on the net, I'm heading to the darkroom to mix up another 1 1/2 litres to replace what I have used this past week.
I've been using Ilford FP4+ since it's inception, it is my work horse film and one I know quite well. I picked up a few boxes of Bergger Pancro 400 when it was released in Australia, it has become my go to film for interesting shadowy subjects, as well as portraiture. The 5x4" version comes in 50 sheet boxes, which is the right size for me; I cannot stand the 25 sheet Ilford stuff (which is why I buy the 100 sheet boxes from the USA), as for kodak and their 10 sheet boxes of some films.....
