Hi Phillip,
Yeah, that's exactly what I find confusing. It's probably just me. If you're in a home lab and you try to stick with film stock that you know, and then the reseller comes and adds a little letter to the name and puts an entirely different film in the box, which behaves completely differently, I find it confusing and unnecessary. If it's a completely different product, just give it a different name, for God's sake.
We have to be fair: All film manufacturers are doing it this way, without exception.
Ilford replaced FP4 by FP4+ and HP5 by HP5+. Ilford Delta 400 had two emulsion changes without name change, one in 1994, one in 2000.
Kodak replaced Tri-X by a modified Tri-X in 2003 when they moved the whole BW film production to Rochester. The film get finer grain and new development times, no name change at all.
Same with T-Max 400: New film with new characteristics, same name. Portra film revisions the same.
In all these cases the films were to such an extent changed, that you as photographer had to test them again and get familiar with their new characteristics.
It is common practise for all film manufacturers to do only small or no name changes when new emulsions are introduced.
If you criticise this practice, you have to criticise all, not only one company.
This kind of discussion I find extremely tedious, so I'll leave it at that.
You have started it, not me
😉.
You get these three or four German film forums full of nerds, who can discuss for weeks on end on what material is in which boxes,
Yes, I agree, worst of it are the stupid guys like cmo, F.S.B; J.B. etc at sw-magazin.de. Ridiculuos people, ridiculuous discussions.
I am using films from Kodak, Ilford, Fuji, Agfa/Rollei-Film, Spur, Foma, Freestyle, Adox, Lucky.
I love to experiment with different emulsions and film characteristics. Every manufacturer has strong films in his programme.
And I am happy about every company on the market offering film products for us.
It doesn't interest me much which name is on the box. If the film is good I am happy.
Cheers,
Jan
