I'm sorry, if you all say those are Tri-X, I wouldn't know the difference.
I now believe that there is just insignificant difference, 400 ASA films are just that, a piece of film that is more sensitive than 100 ASA. How the negative turns out totally depends on your exposure and development.
I am not saying good-riddance to any discontinued films, but we all have to make do with what we have, appreciate it, buy *the ones that are still produced*, use it often. So we don't lose them all.
To those who has never tried Neopan, buy HP5, give the only company who gives a damn about B&W film your support.
If you can't be happy with any of your HP5 images, most likely the emulsion is not the problem.
With all due respect; you are wrong about much of this.
The variations with these films (proven in various tests in the past, when film still had some printing space in photo-magazines), is significant in many areas, but especially concerning:
- True speed
- Grain (yes!)
- Resolution
- Tonal response and sensitivity
- Reciprocity properties
- Curve response to pushing and various developing schemes.
The delta films from Ilford for example, have a much greater red sensitivity than Tri-X, Neopan or HP5+, meaning things like red lips will be almost white and pale, depending on the light.
- I find this extremely unflattering and after trying out the deltas, I simply gave it up for people. Even if the skin is smoother with higher red sensitivity, white and pale lips look SILLY!
HP5+ is a much nicer film and much more flattering tonal response, it has "old school" cubical grain structure and lower resolution than the Delta 400 (which is a newer film with T-type grain structure).
The grain means squat when you print a 4x6 inch print, but it does play a role in bigger prints.
True speed can be compensated for somewhat, but it limits pushing ability, a film with a true speed of 400 will handle a +1 stop with ease, Foma 400 will not, as it's true speed is more like ISO 250.
The look and feel and grain can only be
emulated to a certain point, it will never be the same, because these films simply are
different.
The only Ilford films I personally like, is HP5+ and FP4 (and I actually do buy those).
