UC - 16 Jan 2006 14:47 GMT I finally ran some tests on Tri-X, TMY, and Neopan 400 together in Acutol.
I ran all three films at 1+14 for 8 minutes.
There has been a rumour floating around that due to the production changes made in Tri-X, it was actually finer-grained than TMY. This is quite false.
The time of 8 minutes is on the nose for Neopan 400, but both the Tri-X and TMY could use about one more minute to match the contrast of Neopan 400.
HP5 Plus, on the other hand, requires a bit less time (7 minutes) or a bit more dilution (1+15) to match Neopan 400. I prefer the latter.
Anyway, the grain of Tri-X is still coarser than that of TMY, and, I should add, that of Neopan 400. Neopan 400 combines the fine grain of TMY with a characteristic curve somewhat similar to that of Tri-X.
For that reason, I have switched to Neopan 400.

As far as I am concerned, Neopan 400 is the best reportage film out there, with HP5 Plus and Tri-X tied for second.
Jan T - 16 Jan 2006 18:42 GMT Hm, UC, unless you own a portfolio of shares of Fujifilm ;-) , the fact that you keep repeating the qualities of that film makes me wanting to test some. I am a Tri-X lover for it's tonality, but the characteristic grain, how lovely it can be, is indeed sometimes a little coarse for some kinds of jobs. As soon as my stock of Tri-X runs out, I could maybe switch from the yellow to the green box. Fuji defenitely has something! I'm using the Neopan 1600 with pleasure, and since I developped it according to your advice in Acutol, my prints look better. I must admit I don't quite follow you on the higher dillutions and shorter times, I print with a VC haed, wich is of course a diffusor.
A friend already advised me the Acros 100 for the finer work. Did you run tests on that?

UC - 16 Jan 2006 20:11 GMT I would say that Neopan 400 is just about the best overall 400 speed B&W film on the market right now.
The grain of this film is very close to TMY.
If Tri-X is 100, HP5 Plus is about 98, Neopan 400 is about 95, and TMY is about 90. Anyone who hates TMY is in for a shock if you try Neopan 400. You may prefer it in FX-39, at 1+17 dilution for about 8 min, on grade 3 Galerie w/condenser.

Yes, and it comes in about 1/2 stop slower than FP4 and a little finer grain. It takes about 8-10% longer to develop than FP4.

The grain of this film is very close to TMY.
If the grain level of Tri-X is set a value of 100 (arbitrary scale), HP5 Plus is about 98, Neopan 400 is about 95, and TMY is about 90. Anyone who hates TMY is in for a shock if you try Neopan 400. You may prefer it in FX-39, at 1+17 dilution for about 8 min, on grade 3 Galerie w/condenser.

Behan - 16 Jan 2006 20:03 GMT UC, thanks a million for sharing your test results. I've been a long time fan of Tri-X, too, but it looks like Fuji may outlast Kodak in keeping B&W films on the market. Could be time to switch. Your tests are encouraging that. Thanks again. Dick B.

UC - 16 Jan 2006 20:18 GMT Don't get me wrong: There's nothing wrong with Tri-X. It's just that some people were saying it had been improved. It has NOT been improved, just moved to new production facility, as Kodak says. It looks exactly the same as always.
My point is that if you do like Tri-X but wish it had finer grain, and find TMY unacceptably fussy or unsuitable, Neopan 400 may be of interest to you. Neopan does take about 10% less time, however, at least in some developers (i.e., Acutol).

Thanks to UC for the info though. Nice work.

Tri-X is my 400 film of choice, but I guess I'd survive without it.
I just like having options, and I don't relish my choices getting reduced even more.

After bouncing around and trying lots of different fioms for the last two years, I'm settling on Fuji and Ilford. Kodak offers nothing that is better than those firms' products, and I dislike the fact that both Ilford and Kodak make TWO lines of film. Why not make ONE that does the job? Fuji has done exactly that!
TMY does in fact offer the finest grain of the bunch, but only by a smidgen (or a jot, maybe a tiddle) but the disadvantages of it characteristic curve are just too severe to deal with. Tri-X, on the other hand is old and looks it. It's really showing its age. HP5 Plus is a superior film, in my judgement, but only by a small margin. Neopan 400 is superior by a greater margin. I think that if Kodak had wanted to, they could have improved Tri-X to meet or surpass Neopan 400. Since the latter is superior, I'm switchin'!
If Kodak DOES improve Tri-X, I'll switch back.
Ilford and Fuji have simply passed Kodak by....

If Ilford were to `improve` the Delta 100 & 400 films and call them, let`s say, Ilfopan 100 & Ilfopan 400 respectively and then discontinue the current Delta and Plus series films, I am wondering what the reaction would be with regular users of the present series of films?

What I am trying to say is that Neopan 400 is better than EITHER HP5 Plus or Delta 400, and better than Tri-X and T-Max 400. Fuji seems to have produced a film that gives the best of both (crystal) worlds. Sure, TMY is a bit finer-grained, but Tri-X is woefully old-looking. In trying out all these films, subtleties became apparent. I just cannot see using 5 different B&W films, trying to match them up with different situations. I don't have or need to have 5 bodies. I want to narrow down to just one or two 400 speed films, and one or two medium speed/slow films
Right now, that would be:
Neopan 400 or HP5 Plus FP4 Plus or Neopan Acros 100 Pan-F
Also rans: Delta 400 Tri-X
Film I will not use: TMY

Kodak offers nothing that [quoted text clipped - 6 lines] > Delta and Plus series films, I am wondering what the reaction would be with > regular users of the present series of films? To clarify:
The current approach of both Ilford and Kodak is to have TWO different film lines, with different crytsal types predominating. Fuji has apparently decided not to do that, but to issue films that seem to combine the best of both worlds. Neopan 400 is intermediate between Tri-X and TMY in graininess and curve shape, though perhaps just a bit closer to Tri-X than TMY. It's a 'better Tri-X' if you know what I mean. It's what Tri-X COULD be like if Kodak had decided not to bring out TMY but instead decided to mix T-grains in with Tri-X conventional grains.

So is this one:
http://shutterbug.com/equipmentreviews/film_darkroom_gear/0204sb_kodak/
Tri-X is distinctly grainier than TMY, and the TMY is just exposed a couple of weeks ago looks identical to what I used 10 years ago. the same is true of Tri-X. These films look exactly as they did before.

If the films are actually better I would say I'll buy them just as I have done with the Deltas.

I have switched for no reason other than I like the Nopan better. I have also tested lford Delta 400 and HP5. They are all good products, but Neopan 400 is the best overall in grain (other than TMY) but with a similar charchter to Tri-X.
One interesting point is that the grain of Tr-X looks 'dark', whereas the grain of Neopan 400 looks light. I don't know how else to describe this, except to say that on a grey neutral sky, Tri-X looks like pepper was spilt on it, whereas the grain of Neopan 400 looks like salt was spilt on it. It's very subtle, but of course the irregularities that we call 'grain' are actually the holes between the grains. Somehow, Fuji has plugged the holes that Tri-X leaves. The grain isn't really a whole lot smaller, but definitely less intrusive.

> Thanks to UC for the info though. Nice work. > [quoted text clipped - 3 lines] > jondotrogersatntlworlddotcom > ============================================ UC - 18 Jan 2006 15:03 GMT Last night I made some extreme enlargements (about 14X) and examined them closely.
I still definitely prefer the Neopan to Tri-X and TMY, even though TMY is slightly finer-grained. I just HATE TMY's soft-shadow look. Neopan just looks less 'tired' than Tri-X. I guess I'm sick and tired of the Tri-X look.
I plan on soon comparing HP5 Plus and Delta as well, all in Acutol. I have tested them before, but it's been a couple of years, and TMY/Tri-X were not included.
If you like Tri-X, fine, but I'm sick of it. The shadows are TOO contrasty. TMY goes too far in the other direction: the shadows are too soft. Neopan 400 is just right. It's the perfect compromise between TMY and Tri-X. Tri-X was designed back when lenses had a lot more flare. If you use 1960's Nikon lenses, it's a good choice. TMY is a disaster. Neopan 400 seems to be designed for modern lenses, with just a bit less contrast in the shadows than Tri-X, and thus a more uniform contrast from top to bottom. HP5 Plus seems to be somewhat nondescript.

Keith Tapscott - 10 Feb 2006 19:22 GMT UC sent me 3 scans today of the same subject photographed on Kodak 400TX, 400TMY and Fuji Neopan 400 respectively. Both photographs on Neopan 400 and Kodak 400TMY appear to have finer-grain than the image taken with 400TX with 400TMY perhaps just ahead in fineness of grain. The Neopan image seems to have a bit more punch and contrast in the midtones on my monitor than the Kodak films which can be seen in the grass, hedge and brick chimney stack. I know this seems contradictory to the test for Photo-tech mag, but maybe UC would send the same scans to someone else, to see if they come up with a similar conclusion after seeing them.

[quoted text clipped - 13 lines] > John - Photographer & Webmaster > www.puresilver.org - www.xs750.net UC - 10 Feb 2006 20:07 GMT I developed all three rolls together in the tank at the same time, and because I did not have my own data for TMY or Tri-X, I used the time I have established for Neopan 400 (8 minutes in Acutol 1+14). It would appear that Tri-X might look better at 8.5 or 8.75 minutes, and that TMY would take about 9. Adding a bit of time on Tri-X and TMY would increase the grain on those films a bit, I suppose. The way the comparison was run, it favored Tri-X and TMY, because they received a bit less development than I think they should have, if the contrast were to be matched with Neopan 400. In other words, the Neopan was developed proportionally a little more. The Kodak films do look the same as they always have, however.

If the other two films would have received even more debvelopment, they would have been grainier. Tri-X was ALREADY granier than Neopan 400, so my conclusion is perfectly valid. Extending the time of development of either TMY or Tri-X will not change the outcome in any way.
> In short, your results apply to the conditions in which the tests were performed, and no > more. I compared the films under typical normal conditions of use. What better way to compare films? The fact is that the films looked the way they have always looked. Tri-X looked EXACTLY like Tri-X. The notion that Tri-X is somehow magically finer-grained than TMY is ridiculous, and was empirically falsified.

The differences in contrast are actually not that great. You might want to see the scans for yourself. I estimate that Tri-X could use maybe 45 seconds more time, and TMY perhaps 45 seconds to 1 minute.

The difference in grain and sharpness is quite easily seen.

The 400TMY and Neopan 400 images both appear to have finer-grain than the 400TX image with perhaps 400TMY just edgeing it for the finest grain. The midtones as seen in the grass lawn, hedge and brick chimney stack seem to look best with the Fuji film on my PC monitor. I know this seems contradictory to the test in the Photo-tech mag by Dickerson & Zawadzki, but perhaps UC would send someone else the same scans to see if they come up with similar conclusions from what I have seen from these scans.

"FUJI NEOPAN 400
A good alternative to Tri-X, which Fuji appear to have set out to match - and have done with perhaps slightly finer grain and higher resolution. Combined with a wide exposure latitude and excellent shadow and highlight detail, this is one of the best conventional 400ASA films. It pushes even better than Tri-X, remaining useable up to 6400ASA. It's a film I used for years with students, and occasionally for myself."
This matches my experience.
Then, of course, we get morons like this who write about film:

Van Riper Frank Van Riper on Photography
WHEN NEWER IS BETTER
By Frank Van Riper Special to Camera Works
In the course of running a test camera through the hoops recently, I shot two rolls of black-and-white film under nearly identical conditions.
Yet despite the similarity of shooting conditions, there were dramatic differences between the two films - even though each had the same nominal ISO and even though each was processed identically by the same custom lab.
The films in question were Kodak's T-Max P3200 (TMZ), which has been around for years, and Ilford's Delta 3200, a comparative newcomer to the ranks of high-speed BxW emulsions. To my eyes and contact sheets, there was simply no comparison: the Delta 3200 ate TMZ's lunch in terms of snap, shadow detail and D-Max (richness of blacks).
Oh, the TMZ gave me pictures, all right, but the crispness of the Delta 3200 images was almost unfair by comparison. Kind of like setting beef Wellington next to a Wendy's hamburger. (Sorry, Dave.)
In both cases, I was shooting by available light, to test my camera's meter, but also to compare the two films. Each time, I rated the film at 1600 and had my lab, Chrome Inc., of Georgetown, pull the film one stop. I did this deliberately and, frankly, out of habit. Whenever I work at the edge of the technological envelope - in this case with two of the highest-speed emulsions on the market - I tend to take manufacturer's claims with a grain of salt. So I had the lab pull the film to compensate for the fact that I was allowing more light onto the film than theoretically was necessary. (Here I have to admit: If I really took speed claims with a grain of salt, I would have shot the film at 1600 and had it processed normally - but that's another story and another column.) "
Look, Mr. Van Riper, NEITHER of these films is faster than 800-1000 AT MOST. Shooting these films at 1600 does not call for a 'pull' at all.
In my experience, the Ilford Delta 3200 is FAR, FAR granier than TMZ. I did careful comparison tests several times, and it was not even close.

Mike - 16 Jan 2006 23:26 GMT Have you tried Pyro-based developers? TMY in Pyrocat is lovely. I have not tried Neopan yet.

Pyro-based developers are actually rather grainy, and not good for 35mm films.

Peregrine Rigging - 19 Jan 2006 10:35 GMT At what speed did you expose the Neopan 400? I find that both Tri-A and TMY are actually slower than rated by the manufacturers. I have always exposed them at 320 with excellent results.

UC - 19 Jan 2006 14:09 GMT I bracketed the exposures. I used the same frame in each case (1/500th @ f/8) which corresponds roughly to EI 250.
I rate all ISO 400 films at around 250-320. Wait for my book and you'll see why this is a good universal practice.

Which film is more or less grainy in practice depends on too many factors to go into here, but suffice to say that blanket statements of fact by one unnamed person without qualifications of any kind should not be taken too seriously. UC has offered nothing of more substance than his opinion of a few 400 speed films. His claim that pyro developers are too grainy for 35mm film, even though he's never used one, is very telling. He is clearly relying upon outdated literature as the basis for his pronouncements. Modern staining developers produce no more grain, and often less grain than comparable non-staining, acutance developers. UC's film speed ratings might work very well with his system and condenser enlarger, which exaggerates contrast, requiring a reduction in development, which in turn reduces fim speed, but those who use a diffusion enlarger might require less exposure, and more development for easy printing negatives. Since we're noting our favorites, mine is TMY.
UC - 08 Feb 2006 15:24 GMT > In controlled tests performed by qualified professionals, new TX shows > less grain than TMY. It certainly does not, at least not when developed in a metol-hydroquinone or phenidone-hydroquinone developer. I developed three rolls of film at the same time in the same tank, in Acutol 1+14 for 8 minutes @ 68F: TMY, Tri-X, and Neopan 400. The TMY was slightly finer-grained than the other two, and Tri-X was by a sight margin the grainiest. This is not unexpected, as it is an older-technology product. I can send you scans if you wish, to prove it! I will trust my own eyes before trusting your unsupportable rantings.

Since > we're noting our favorites, mine is TMY. ujazz32@hotmail.com - 08 Feb 2006 17:53 GMT The new Tri-X vs TMY comparison studies were conducted by Dick Dickerson and Silvia Zawadzki, both former Kodak research engineers responsible for the development and testing of many Kodak B&W products. Their finding were published in Photo Techniques magazine,in an article called "Testing Kodak's (remanufactured) Black-and-White films", and the details of their testing regime can be found therein. The only "unsupportable rantings" are your own, and which are truly "utter rubbish".

Dick Dickerson and Silvia Zawadzki, are both 'former' Kodak research engineers because Kodak 'invited' them to leave. Who are you going to believe? Kodak AND me, or Kodak's rejects?
ujazz32@hotmail.com - 09 Feb 2006 21:28 GMT UC,
I don't know the details or circumstances under which these two people left Kodak, and I'm willing to bet you don't either. Suggesting they are/were incompetent is obviously a very defensive reaction on your part. Both Dickerson and Zawadzki are current contributing editors at Photo Techniques magazine. If you have questions or concerns regarding their qualifications, they should be addressed to that publication. Your own qualifications and credibity are far more questionable, and given the choice between taking Dickerson and Zawadzki's published findings, or your personal opinion, is not a difficult one. The full article referenced is available at the American Highway Project website.

It would be absolutely amazing if the films turned out to be anything but very similar to what they were before.

I know that Tri-X and TMY look basically the same now as they did before. Is that surprising? No, of course not. It would be shocking if it were NOT true.

My tests showed NO CHANGE from before.
KODAK and I agree. What more could you want?

I read that article. It is utter rubbish. Did you know those people were 'invited' to leave Kodak? My testing showed the films behaved as they always have. It would be surprising if they did not, especially since Kodak says the films should behave as they always did. So, who are going to believe? Kodak AND me, or two people who were kicked out of Kodak?
