I recently decided to try out some Efke 25. However, the biggest problem with it is that it will not develop with my standard developer (HC-110) so I decided to give Fomadon R09 a try since Rodinal is not in huge supply at the moment. Checking the Massive Dev Chart they reccomend the following: 1+40 ISO25 6 minutes 1+100 ISO25 18 minutes Any suggestions on which dilution I should give a try first. I use a small patterson tank (haven't quite got the hang of stainless steel) so are there any agitation reccomendations? For my other films in HC-110 I used to do the first 5 seconds of every 30 seconds. Thanks in advance for the advice.
