Dev time for Efke PL 25 M using Fomadon R09 1+25

[vrpd91]

I'm looking for the development time for Efke PL 25 M using Fomadon R09 developer at 1+25 or 1+50 dilution. The film is said to develop at 6 min using D76. The developer paperwork is not much use as the only Czech figures are for Foma FP100, 200 and 400 at 4, 5 and 6 min. respectively. Ilford's 50 speed PAN F-Plus comes in at 6 minutes so i think i'll start at 6 min @ 68 degrees (1+25) if i don't hear any objections?

Maybe you should check the times for Rodinal. The R09 part of it's name implies that it's (more or less) a Rodinal clone. IIRC the suggested dilutions for Fomadon R09 are 1+20 and 1+40, which should be equal to 1+25 and 1+50 for Rodinal.

Where can i get the times for Rodinal?

The massive dev chart at digital truth has some suggestions.

(there was a url link here which no longer exists) has some interesting information too. You might want to try the 1+100 dilution (stand development), many members have reported fine results.

If you have the Fomadon R09 NEW with rounded corner bottles and 1+25 and 1+50 dilutions, you HAVE Rodinal/R09 one shot developer made by CMS in Vaihingen-Enz.
During this summer Foma changed from R09 supplier.

So you can execute the Rodinal data for this stuff.

The rodinal times on Massive Dev worked well for me .

What disturbs me is that massive dev chart mentions simply "Efke 25" so it's not clear whether it is PL 25M or KB 25. I have got some PL 25M sheets that I want to shoot and develop in Rodinal. I think I will expose at E.I. 25 and developer in 1+50 dilution for 8 minutes or 1+100 for 12 minutes. Any tips on the stand developing Efke with Rodinal? Is pre-soak recommended with this film? Thanks
