New Tmax 100 and Rodinal

I looked on the "Massave Dev Chart" under new 100 Tmax and couldn't find any times for Rodinal. Is any one out there using this combo yet? If so what is the time for 1:25, 1:50 and 1:100 at 68 degrees? I want to stay with one developer for all my b&w needs. Thanks.

You can start from the times to the old version of Tmax 100 and then adjust the time so that you get the contrast you need.

According to the Agfa chart for the old TMx. 1+25 = 5 and a half minutes 1+50 = 12 minutes

Add 10%, if you plan to presoak.

I downrate to 50 ASA and dev in Rodinal 1:50, 20 C for 6.5 minutes. I use a condenser head enlarger. Thus for 100 ASA I would suggest 9.5 minutes (condenser head) and for a diffuser head 11 minutes.

I use 13 minutes at 27°C, with a 1+100 dilution of Rodinal. I get great results, and output to my film scanner is fantastic.

At that dilution, there is quite a bit of margin for error, and I've got great stuff all the way to 14 minutes. :)


100TMAX in Rodinal 1+100 for 13 minutes at 27°C

I forgot to mention that the above sample was exposed at ASA 100...

Anyway, a quick conversion on the temperature chart yields a time of 24 to 25 minutes at 68°F.

Cool. Thanks for the info. I did some testing this weekend. I shot a couple of rolls of 100Tmax-120 in bright sunlight with some nice shadow areas. I developed one roll in Xtol, two minutes over the recomended time at 68*(the * is my way of saying degrees). Then I developed the other in Rodinal 1:50 @ 68* for 12min., the old Tmax time for this dilution and temp, that's two and one half minutes longer than the new time. I don't have any conclusions because one roll is still drying. Both rolls look nice but the Rodinal roll looks better I think, more shadow detail, more contrast and more midtones. I have to do more testing but I have some favorite outdoor subjects to test on that I love to keep going back to so I don't think it will be long before I get the look where I want it.

I shot and developed my first roll of TMAX 100 this weekend. I developed it in Rodinal 1:25 for 6 min at 20C/68F with one inversion per minute. I have a condensor enlarger and the film was rated at 100 and the day was overcast with a slight bit of sun peeking through. The pictures came out fantastic. I'm hooked. I used grade 2 and 2.5 for most of the pictures that I printed and at 8x10 size the grain is barely noticeable and the tone is excellent. I've been using FP4+ and this film beats it hands down for fine grain size. I'm going to try it in 1:50.
