Developer for Adox CHS100 ii

[koraks]

Anyone using a fixer with hardener to control the curl?
Or would that make it worse?

If anything, it would make matters worse. But realistically, it won't make a significant difference.
The curl should disappear by simple flattening of the sheets with negatives under pressure over time.

FWIW it seems like CHS100 ii might be ORWO UN54 emulsion coated onto PET base. Obviously I don’t know this for sure, only Adox can (and won’t) confirm, but the spectral sensitivities are remarkably similar. Could be worth taking a look at developing times for UN54.

To my experience with both UN54 and CHS 100 II: No. They are different. UN54 has the finer grain, and CHS has a very good anti halation layer.

I don’t think it’s repackaged film, but I do think that Invusicoat is coating the sane emulsion on PET film base for Adox, with added anti-halation dyes.

For 4x5 - I love the Adox CHS 100 II in 510 Pyro, 1+300, 21°C, 2h stand development - came out perfect.
