Yes
Last ORWO NP20 I did in RODINAL 1+50 was under-developed . The Rodinal was now a ' Dark Brown Colour' with Crystals at the bottom -- so I gave it a 'test' -- I microwaved it gently at 50 for 45 secs several times, trying to break up the Crystals as I did so . It got quite 'Warm' ! I cut the short length of ORWO NP20 rated 50 ASA in my Chinon CG-5 and processed in RODINAL 1+25 for a 'Guessed' 10 mins @ 20oC and got GREAT NEGS !! I could have rated the outdated film faster at 64 ASA even . I have scanned just TWO to show you . I will use up the rest of the 'Brown Microwaved RODINAL' now ! THIS one was using my SMC Pentax-A 24mm f2.8 to see if I could 'Hand-hold' it in dreadful light at f4 -- I think I managed it -- got 1/15th second.

That's interesting Peter... I think you should perhaps have put this on the F&C section as it's at least as much informational as picture sharing!

I might well give this a bash, my rodinal has done the same thing and I have to say I'm liking the tonal range.

Thanks for sticking the post in the alert thread, I've a feeling I'm gonna find this useful
 
Happy to help -- that is how we learn tips even though we may have been ' Into Photography' for many years ! I have some 1993 dated Ilford HP5+ on the go at the moment to see how it compares with FX-15 1+1 to the Brown Rodinal 1+25. THEN I will try my FRESH FP4+ as soon as weather breaks -- ( Christmas Present!
