More specifically the FX39ii works best for T-grain films according to the manufacturer, but I used it once for T-max 400 (35mm!)
I seem to remember that Henning Serger wrote in this forum that he got record numbers in terms of resolution with that combo. Definitely will try that since I got quite a lot of TMY-2 for a good price.

Xtol is very nice but has a less pronounced grain which is mostly not my choice and I find the quantity of 5ltr stock too much, where I don't like powders in the first place.

Adox XT-3 made the whole mixing aspect much less of a hassle (less dust and better dissolving without caking of the second bag). I divide it into 500ml glass bottles, takes a bit more space but very convenient because I don't need to measure anymore. I just pour one bottle into a 1.5l measurement cup, fill it up up to 1500ml for 1+2 and process three 120 or five 135 films in one go in a large paterson tank.

That was pretty much my experience with a partly used 6 to 8 month old bottle. I didn't gas it or put it into a brown glass bottle, but will if I buy more.

Thanks for sharing. I really like your Delta 100 results. Which 11K dpi scanner are you using?

Huh? No it isn't. Make the print then scan the print. Sure, it's still a scan but the enlargement of the details is done pretty much entirely optically.

well, what I meant is that in my experience, the print on a wall will look different then a scan of the print viewed on a screen.

But as mentioned, with a wet print the difference in grain texture will be less pronounced (which can be a good thing depending on taste) since the common enlarging lenses are somewhat soft.

I rarely do wet prints of b/w anymore (I still do color sometimes for my own pictures). I mostly scan for people who want to do very large prints (like 150 to 500cm wide) and use a hybrid workflow.

Anyone like FX39II when using Kentmere 400, HP5+, Delta 400 or Foam 400? Those are the only ones I might be using when it comes to "higher" speed films.

I tried FX-39 II with Kodak Tri-X, Ilford HP5+, and Arista EDU 400: the results were ok, but a bit too grainy for my taste. I used 1+19 dilution, 8 min @68F to control the contrast. It worked very well with slower "modern" film like Kentmere 100 and T-MAX 100. But with traditional film, it seems like I don't get the full ISO out of them. The negatives are a bit thin. Thus I reverted back to F76 1+9 for higher speed film.

It's a custom made scanner that I've developed myself over that last several years because I've been disappointed with the results of the usual scanners like Imacon/Hasselblad or drum scanners, neither of which being able to capture the full texture of analog film.

It can scan up to 40'000ppi, but the sweet spot for most films is around 10'000ppi. with some fine grain films it's worth going to 20'000ppi for extreme enlargements.

Fantastic! Hats off to you. Can you patent it or is it based on patented designs (eg digital camera + repro stand etc)?

I have some Kentmere 100 120 and like it very much, but that's with XT3-R and not FX39II. Are you saying you couldn't get "box speed" with Kentmere 100 and FX39II? I easily can get box speed with XT3-R and Kentmere 100.

It's probably not possible to patent it since it's just a light source, a lens and a sensor, which is how nearly all scanners have been operating over the last 20 years.

the challenge is in the details and the tolerances once you go over 5000ppi. it's very hard to get accurate focus until the edges with 10'000ppi and at 40'000ppi the depth of field is thinner than the emulsion layer, meaning one has to use focus stacking to get all the grains in focus.

Perhaps you should start a thread about your scanner in the Scanner and Scanning sub-forum - this part of the discussion would fit better there, and people interested in the subject would be more likely to see it.

yes, good idea. I created a new thread there, so any scanning question can be addressed:

while discussions about film and developers can continue here.

I did not write clearly. For Kentmere 100 and T-Max 100 I got full iso speed with FX-39II. The negatives look great and scans well.

But the negatives from FP4+, Arista EDU 400, HP5+, and Tri-X are a bit thin with FX-39II at 1+19 dilution.
