Hi everyone,
As there has been a lot of talk recently about the longer development times for the latest batch of ADOX CHS50 / Efke R50 (roll film), I decided to try developing a roll in Fomadon LQN.
1 + 14, 20 degrees, agitate for the first 30 seconds and then for 10 seconds every minute, 10 to 11 minutes.
(Note: The minimum developer volume per film is 21 ml of concentrate; for two films in a small tank, you need a stronger solution.)
The result looks good, the dynamic range is good, and prints come out nicely at a gradient of 2.5. I can’t say anything about the effective ISO sensitivity; I was shooting with a flash at a party on a whim and was also quite drunk, which would prove that the new batch also exhibits the R50’s famously high tolerance for errors.

That’s a bit of a load of rubbish, of course. To give us any chance of understanding your times, you should have mentioned just how drunk you were. Without that information, we’re left standing in the woods, having to test our drinking skills.
OK, fair enough… Cheers!

Beer, wine and slivovitz. But I had a different one with each shot, so unfortunately I can’t provide any scientific proof...

Here are the times (still only applicable to the last batch of CHS 50, and only for roll film) for a 1+10 dilution, this time recorded soberly and using a light meter.
Fomadon LQN 1+10, 20°C, 7:30 mins, agitate for the first 30 seconds and then for the first 10 seconds of every minute.
The result is relatively, but not excessively, dense negatives which, with Normal gradient (fixed gradient N or Agfa gradient filter 2.5 with Fomaspeed), still have some reserve in the shadows and highlights; gradient 2 would probably also work, if required due to subject contrast.
As always, I can’t say anything about the effective ISO sensitivity due to the lack of a densitometer. Overall, the latest batch of R50 also seems to develop well in Fomadon LQN – it’s a matter of taste, of course, but somehow the combination works beautifully.
