My 1st impressions after shooting in a Nikon FE Micro Nikkor 55/2.8 and developing in the special developer 1+15 for 8 minutes:
- Base is very thick and sturdy, easy to load in the spirals but my scissors fell from the table and pulling the final tab from the roll was very hard. It has a nice color (almost trasnparent)
- No curling
- I exposed the film as EI32, ina copy stand with flash/artificial lights which burnt some highlights (for scanning) but should be OK for darkroom printing It maybe better to rate this as EI64 for artificial lighting
- The last frames were exposed outdoors and those seems to be fine as EI32

Looking through a 8x loupe I could not see grain, I'll try looking thorugh a microscope to find any grain.

and a 100% crop

UPDATE, there is grain visible with 50X microscope (5x in ocular+10X in objective)
The grain is much smaller than NeopanAcros (the only negative I had handy for comparing)

Folks, I have just developed my first roll in the special developer. Exposed at ASA40, I used de ionised water for the developer, no stop -as suggested. Temp 20.5 C for 6.5 mins. Great negs, fantastic film. However, I do have a gripe - the amount of developer gives 250 ml of working solution. It suggests to use plastic tanks, which I did - but they take 300 ml. No problem I though, shaking every 30 secs would wet the film OK. Well negs on outside of spiral OK (say first 6-8) but all others had under developed marks on one edge. SO PLEASE, JUST A LITTLE MORE DEVELOPER IN THE BOTTLE SO I CAN MAKE 300 ML WORKING SOLUTION. The film has NO visible grain to the naked eye on 8x12 inch prints. Ilford pan F +, I can see 'grain crumps' in certain areas on 6x9 prints (and I expose that at ASA 40). Again great film, but please bigger bottles of developer.

Oh my god. This is the film I've been looking for.

I was just about to ask for a very contrasty film with as little grain as possible. Then this thread popped up.

This film looks like my answer.

If I were to get some rolls of this, when should I use what ISO and why?

Still a newbie to photography. Ha.

Screw it, I'm going to order some right now.

You may want to try one of the chromogenic B&W films such as Ilford XP2 or Kodak BW400CN and over exposing a few stops first. That should give you fine grain and high contrast. It will save you messing about with this specialized film with its special development process.

Just because they recommend a developer doesn't mean that it has to be the one used.

To go further.

If the film is as much like Tech Pan as 'they' say, HC-110 in the dilution that Contrastique used may work well as an alternative.

I have asked on other threads for alternative developers, but there has been no one who has actually tried it. Other mentioned that work are just as hard to get as the recommended one. Please someonet recommend an Ilford or Kodak developer for this film, but only if you have tried it - and it works fine.

To get full film speed from this type of film a developer with a high concentration of phenidone may be used since the oxidation product of phenidone is an inhibitor of development that controls the contrast.Dimezone may be similar.The only Ilford or Kodak product of this type is I believe Kodak Technidol.Alternatively there is a time for dilute Rodinal here:

I don't have a darkroom yet (it is hard to convince others to let you commandeer a bathroom), so it doesn't really matter to me.

Now, at least.
