Can you develop Adox CMS 20 in Adotech II?

harrygrey382 · Sep 8, 2012

I've got two exposed rolls of Adox CMS 20 and 3 rolls of unexposed. I've just moved country (to Australia) and am just getting ready to get developing/printing again. But I see they have discontinued Adotech developer and replaced it with Adotech II. They say you must use Adotech II with CMS 20 II but don't mention the other way round.

Does anyone know if I can use Adotech II with CMS 20 (I), and if so would the timing be the same? If not does anyone know of a source of Adotech (I) in Australia or failing that anywhere in the world?

Many thanks.

Yes, You can.
On fotoimpex.de You have a note about it:

In case you don´t have ADOTECH I developer left use the time/temperature combination for 20 ASA from ADOTECH II

The pdf with info in english is here: http://www.adox.de/CMS20_ADOTECHII_instructions.pdf

@24°C for 10 minutes
Read carefully the instructions and its good practise to use distilled water, especially with this film.

Good luck!

Else you will end up with strange spots, the calcium binds with chemicals on the emulsion. I had quite some troubles with this, until I finally changed to distilled water.

I prefer DIAFINE with ADOX CHS film...

But as that's not the question, I defer to those with experience with different developers.
Just my preference

10 Minutes @ 24°C is OK in order to develop a CMS II film eposed to 20 ASA but my latest tests showed that old CMS comes so contrasty that I would actually suggest developing it 8 Minutes only and rather sacrifice some shaddow detail.
But this is Beta information. We do not recomend ADOTECH II for CMS 20 I.
I am among you guys though in having forgotten to develop all my CMS 20 I in old ADOTECH and now I have to figure out the best way to use ADOTECH II.

wow, glad I asked this thanks guys. 24* 10min is vey different from the 20* 5.5 min I was using with Adotech I! Sounds like I'd be safer using one of my 3 unexposed CMS 20 Is as a test film to find a new developing time with Adotech II, based around 8min at 24*. I'm assuming 20* will make times just way too slow?

Out of interest, are there any more changes to this film/developer coming up? Don't want to buy a heap of film and find out there is an Adotech III or even worse no developer...

I do not understand the dilution specs on the bottle. It states: "1+14=33ml +467ml of water for two films."
Am I obtuse or are these directions counter-logical?

Comments welcome. Thanks, Fred

The instructions are to dilute it 1 part stock plus 14 parts water.

To fill a 500 ml tank, take 33ml of stock (1 part) and add 14 parts of water. 462 ml would be exactly 14 parts, but it is probably easier to just add enough water (467 ml) to bring the total volume to 500 ml.

I've done Adox CMS 20 in TMax developer with good results!

Were you able to use its full speed of 20 with TMax? It seems to be a film that can only be used at "box speed" with the Adotech developer.

Thanks

Yep, shot at ASA-20, found the formula burred in the Massive Dev Chart. This is from 120 film, formula on MDC is for 35mm but seemed to have worked.

1+14 or 1+29?

still confused:

- bottle label indicates "1+14 = 33ml +467ml of water for 2 films"
- Adotech II "Developing Instructions" indicate "Dilution: 1+29"
- CMS 20 data sheet for "other tanks" indicates "300ml from 16,5 ml of concentrate"

Use the instructions on the bottle of Adotech II you have. The best results in terms of shadow detail I had was stand developing in some Perfection XR. But I'm sure that may be the same as lesser dilution non-stand, which I've found very little difference in most cases to stand developing unless the stand developing overdevelops the neg and puts a heavy shoulder on it.

those T-Max results look very good for CMS 20. What's the density of the neg look like? The advantage of Adotech II is that it very lightly fogs the base (thats otherwise clear) so that the film can be seen and read in automatic readers, like minilab scanners.

Yes, that's what I'll probably do.

5 years between your last post and this one. Amazing.

Slightly off topic, but where else can one ask a question and have the head of a photographic film company personally answer questions? I love it!
We as a community are very blessed.

following the bottle instructions seems to be the way to go.
