Adox CHS 25 + Ultrafin plus?

[jernejk]

Hi,

I'm currently shooting Adox CHS 25, but I only have Ultrafin plus developer at hand. I found no information on this combo.

Any ideas? Or should I get the recommended developer?

Thanks

Take a gander at the massive development chart at: http://www.digitaltruth.com/devchart.php?Film=Adox+CHS&Developer=Ultrafin&mdc=Search

I think this will cover it.

Unfortunately it doesn't. There's a lot of data for Ultrafin, but not Ultrafin Plus.

Sorry, missed the "plus". The Ultrafin plus is supposed to be great for t-grain films, but rates low for conventional grain films. I checked a few sites, couldn't find what you need, but I did find quite a few films listed , such as APX and Plus-X. Maybe you can start with the regular Ultrafin times, and do a snip test to find a good time.

After searching the MDC further, looks like the common dilutions of 1+4 and 1+6, with the latter dilution recieving 50% more time for development. I did see a 1+9 dilution, but for a not to common film. I would try 1+6 for 10 mins@ 20c using standard agitation for a starting point. Just to be safe, I would use a clip test just to be sure.
