Anyone know if these people were ever in business?

Film was reported to have resolution 3x that of Tech Pan. No idea if
it was for real.

 

Yes, it was for real, and I think it is still available. The UK
distributor is about 20 miles from where I live.

I tried the ISO 40 version but it was too contrasty even with the
supplied low contrast developer. So I tried several other films
before settling on ADOX CMS 20 which has higher resolution and much
lower contrast, provided you use the special ADOX developer. It is
very easy to find and reasonably priced too. The only drawback is the
low speed, ISO 20.

I now use ADOX CMS 20 along with Kodak Professional BW400CN. If Kodak
sells its film production I may have to switch to ADOX Pan 400 to
replace the BW400CN.

ADOX CMS 20 can produce negatives that are as detailed as Gigabitfilm.
If you wish to scan the negatives, there are no generally available
scanners that can get very last detail out of them.

 

Thanks, I have a darkroom (still!) so I can print directly. Inkjet
printers capable of 20x24" prints are costly. But it's easy with an
enlarger.
