Tri-x vs. HP5, a simple test I did.

Hats off to you Sir!
 

The Fomapan, & Agfa (old) also dry flat on the cloths pin, after four hours hanging. But curl can be dependent on relative humidity so YMMV.

Neopan 400 was nice concur.
 

Yes, that is right. Noel's photos are very good. And he shots that many rolls!

And yeap, going a bit back, we discussed another day the alternatives in film and personally I like the Kentmere films as well as the PAN ones. I can't see much difference in them, but there is some.

Well, this was off topic.
Thanks Brian for your tests.
 
Yes Brian was nice to publish his comparison thanks, and although eg Kentmere400 is a lower technology film to HP5+ it still has a similar signature.

Is is cheaper.

A 15 print three film blind test of 16x20 you should pick out the Kentmere you might struggle with the other two.

I'll be upset if doublex dissappears, as it is finer grain.
 
Here are films scans. Again, not much difference IMO as far as grain. Most think HP5 is grainier, as I always have. The Tri-x is on the left, HP5 on the right. They are 3200dpi scans of the chimney from frame #11. Scanned on an Epson V600.

My Ilford order came in today and I'm anxious to try the HP5. I've used quite a bit of it in large format, but not much in 35mm for quite a number of years. I ordered 100' of HP5, FP4, and Kentmere 100. I've been shooting Kentmere 100 lately and liking it. I haven't done a comparison lately, but it seems remarkably like TX. A bit finer grain, but I think similar tonality. I had tried it when it first came out and wasn't all that enthused since it is grainier than most 100 films, but it is nice to get Ilford quality control in the cheapest readily available 35mm film. Very nice for general messing around. I'm anxious to see some darkroom prints from it, but it is going to be a while before I get a chance to do that.

I couldn't see any difference worth talking about. Heck, they look like the same negative, scanned with different dust.
 
My gut reaction was that things look rather muddy here too. If the negs are underexposed or underdeveloped, might that not influence our reading of the similarities and differences between the two films? Or do folks feel that these contact sheets are pretty much perfect?

Those contact sheets are dark and muddy looking. They really don't tell us anything. Enlarge some of the photos with the correct print exposure and contrast to make each individually look its best. I like both films, but they're not the same.
 
After looking at the scans I´m even more surprised. When the new 400TX was released some 10 years ago many people claimed that the grain was much finer than before. At this resolution, I had expected it to be visibly finer than HP5+ but now I cannot make out any difference.
 
Blind wet print test @ 16x20... might be different.

eg as scanning may be masking differences.

When a supplier changes sometimes it is for factory act safety cause of toxicity like lead glasses were banned... they normally say it is a typeII lens... etc.

I don't use HP5+ for grainy instead Fomapan400 gives nice grain.

Double x is finer than HP5+ and faster than FP4+... 250 ISO is close to 400.
 

I agree. However when I look at the negs through a loupe HP5 still looks a little grainier. It may be a different story with optical printing since scanners pick up grain like crazy. I might wet print that same section of chimney on 8x10 paper an scan the prints. That would be a better test.
 
Please don't waste a big sheet on tests a pair of post cards on a small section with enlarger on max...

Keep it a secret and ask unbelievers to guess.

Great!


I think there is some contrast enhancement in the scan, which could obscure some of the subtler differences.

Otherwise, I still see a fraction more contrast in the left scan.

Gran is impossible to call, especially as the films were't developed exactly the same.

Again, a well-performed test.
 
Pick One


Brian: if you had to pick one and only one, which of the two films would you pick? HP5? Tri-X?
 
Brian, how about exposing at box speed so that the test is actually meaningful? Not using box speed is muddying the waters with muddy scans.
 
Gran is impossible to call, especially as the films were't developed exactly the same.

Well they will need the different development for the same gamma?

And it is a difficult call for me to separate

- doublex from HP5+ on grain.
- Kentmere400 from HP5+ on grain

IDK about Brian but if I had to pick one. Yes.
 

Wow, this is a massive amount of work for a couple of keepers per week. Almost a full-time job.

Regarding your comment on autofocus on the Fuji x100, have you considered using a mirrorless digital body with a legacy lens? Then you could use hyperfocus for instant snapping. It would save you an enormus amount of time and quite some money too. Processed with Silver Efex, most people wouldn't be able to tell the difference from film anyay.

Funny you should say that, Brian. I tried Tri-X about 20 years ago when all I shot was color. Was never satisfied with the Tri-X shots. A couple years ago, I tried HP5+ and love it for B&W.

Don't be. I found your test useful. I have debated moving from TriX to HP5, and recently bought my first 100 ft. of HP5. Your test reinforces the need for me to learn how to use the tool of HP5 with a scanner. Thanks!
