Adox CHS processing...tank...drum...?

Apart from silver print and ag are there any other stockists of the adox films here in the UK?

I'm off on a shoot this friday and wanted to try some CHS50 54 film out...but none at silverprint and ag may be getting some in..or may not...in next few days.

Thanks,

Marc

I've had parcels from Fotoimpex in Berlin arrive in 24hrs

They open and close later than most stores, sensibly Mirko realises many people can't shop during office hours. He has a contract with a courier service so you aren't relying on the Post Office. Minimum charges may be a problem though.

Thanks Ian,

I'll see what ag say tomorrow.

So for processing adox sheet films, do combiplan style tanks or jobo drum (say 2000 with reels) have any advantages /disadvantages over eachother in the way these particular films are handled?

Thanks.

I've found the Jobo 2000 tanks far better than Combiplan or Yankee tanks, I've had one since 1976 and it's had a huge amount of use with no problems. I now have a second in Turkey, The 2000 series are the inversion type, pre rotary. I've used aq Combiplan & own a Yankee for 9x12 film it's far harder to get good even agitation.

Thanks Ian,
So the apparent noted fragility of these adox chs films does not suffer at all with being curled onto the spirals as opposed to hanging flat on the combiplan style holder?
And do you simply do the whole process including force washing in the tank, using inverse agitation I assume?

Thanks,

Marc

Marc, all my 5x4 Adox/EFKE film has been processed in the Jobo and 35mm Adox in Paterson tank, the curvature makes no difference at all.

They are far softer emulsions but I find no problems developing in Pyrocat HD which is a tanning developer anyway so hardens the emulsion further. I used to develop the PL25 in Rodinal or Xtol with no issues there's some hardening now unlike when I first began using the films in the mid 1970's.

BTW the uncoated Paragon is 163mm which may be to short for you, PM me if interested.

I've just last night developed half a dozen Adox CHS 50 in a combiplan:

- 2 minute pre-wash
- 10 minutes develop in APH09 40:1
- 2 minutes wash in Tetenal hardener 50:1 (I got my sums wrong; I was aiming for 25:1 - I blame a stinker of a cold)
- 4 minutes fix in Adofix at 6:1
- 10 minutes rinse and wash.

All at 20C. My tank's inversion capabilities are more in hope than anger, so I tend to give a good slosh once the chemistry's in, and with the developer, swoosh it around at 1 minute, 5 minutes, and 9 minutes - hopefully this has given some edge accutance effect. They're not quite dry yet, but they seem ok; no obvious damage to the emulsion and it looks at a casual inspection to be a sensible sort of density.

Ok so I love Efke's Adox. As for tanks, I have a Jobo that I found bu chance, but I also have an adapter for a Patterson 3 reel tank. It's made by Mod Photo - they sell on eBay and it's great to load and unload.

They dried out now; I 'scanned' then by the simple expediency of using the laptop as a light box, shooting them with an Olympus E-400, and inverting the results. The loss of resolution, completely incorrect gamma, vastly reduced dynamic range, and aliasing effects are mere courtesy details. I'll scan and get them on my web site when I'm back in the UK. But they show that something stuck to the emulsion which is a Good Thing[tm].

The camera is a 1950's MPP Press with an (as far as I know) original Xenar lens that's been on there since I got it.

(in the days of my youth I had a tiny laptop whose screen was close to the size of a 4x5 negative; I wrote software to tickle one pixel at a time and a light sensor under a conical hood. The results were rubbish...)
