Delta 100 in Rodinal

[brian steinberger]

I ran my first tests tonight with 120 Delta 100 EI 50 in Rodinal 1:50 at 68 degrees for 9 minutes with a 2 minute presoak. Way OVERCOOKED! My agitation is first min. constant agitation, then 10 sec every minute. Anyone have recommended times for this combo? The shadow detail is very good at EI50, but with the negs being overcooked I could probably get away with EI64. Thanks!

Don't presoak ilford films. When i shot the stuff, i rated it at 125 for rodinal and used the massive dev chart times. This is my opinion of course. i'm not a fan of the film any longer.

My Delta/Rodinal Experience

FWIW, I also used the massive dev chart with 1:25 Rodinal and Delta 100 at EI100 (this is also 9 minutes). Format was 35mm, not 120, and metering was auto with Leica M7. No pre-soak, 30 secs agitation to start and then 3 slow inversions (about 5 secs) every minute. This is my normal routine. Results were ok. See the Fruit Vendor Pals for an example.

I honestly can't see why yours were overcooked, as it looks like you did everything right. It's hard to believe that pre-soak and agitation would have a such a dramatic effect. Nor does the 35mm vs 120 format seem to explain anything. Are you confident with your metering?

I can tell you what I do. Delta 100, E.I. of 100, Rodinal 1 + 50, 14' 30" at 67 degrees F. Agitate first 30 seconds then five seconds every two minutes. This combo works well for me.

Are you using a condenser or diffuser head ?

The thing with rodinal is that you must use slow agitation. That cannot be emphasized enough!
Also... with most of the films today there is almost no reason to pre-soak film. It's especially not necessary with Ilford films. I use Ilford, Fuji Acros & APX 100 and have never had to do a pre-soak with any of them.

I use 1:50 at 14 minutes, 68deg F, agitation (very slow) for first 15 seconds, then 4 slow "twist-y" inversions at each minute.

I used Delta100 EI100 with Rodinal (1+50), followed the rodinal instruction on the bottle. It came out nicely.

Now I use foma200 with Rodinal 1+50.

Tom,

I'm using a diffusion head. I'm very confident in my metering. I couldn't imagine the presoak being responsible for such dense highlights. My agitation is normal to what I use with other combos. I've never heard about slow agitation with rodinal.

I've found out that proper agitation is a important factor for success with Rodinal, with my best results coming from gentle inversions and longer intervals between those inversions. I haven't nailed down Delta 100 yet, I don't shoot it that often, but Acros souped in Rodinal is AWESOME I dilute Rodinal 1+100 and devlop it for 18 minutes at 70° F. I start out with thirty seconds of gentle inversions , 2 seconds for each inversion, then 2 inversions every 3 minutes for theremaining time, followed by a 2 minute running water rinse and regular fixing, hypo clearing and washing proceedures. When I get everything right, eposure, focus and printing, the results can be stuning., even with 35mm and a condenser head.

I've never heard about slow agitation with rodinal.

If you're curious, and have some serious time to kill, a search of APUG for "stand rodinal" pulls up 293 threads. There should be a couple more by next week.
