Acros and Ilfotec DDX

[WoolenMammoth]

Anyone have much experience with Acros and Ilfotech DDX? Ive been shooting acros at 100 and processing in 1:4 DDX at 9 mins and keep getting pretty burned through blown out highlights. It looks sorta cool, but Id like to avoid it in the future. Any suggestions on what I may be doing wrong?

thanks

In contrasty conditions it's best to shoot at a lower EI and reduce development. For instance shoot your Acros at EI50 and cut time by 20% (giving about 7.5 minutes). You could also look at reducing agitation if you want to keep using EI100.

You can use DDX more diluted, too. Some have reported half strength (1+9) and other values in between.

9 minutes in DDX 1+4... that sound like overkill unless you are exposing 100 or higher.

I'd try with DDX 1+9 for about that time to start with

However, my personal favorite for Acros is Rodinal

I just did an exposure test and at 1:4, 9 mins, Im two stops hot. That was pretty suprising. I got the 9 minute start point from the masive dev chart.

Acros in Rodinal is awesome but ddx with a 70's cron is pretty awesome.

Acros is pretty intolerant of any overexposure. I never tried it in DD-X, but after trying several developers, I'll add another vote for Rodinal.

1:50 - 8 1/2 minutes, 1 tilt every 30 seconds.
1:100 (best results IMHO) - 18 minutes, 15 seconds agitation in each of the first 3 minutes and 1 tilt every 3 minutes after that.

2 stops! holy smokes!!!
is your thermometer calibrated? is good to chekc them against a good thermocuple or a mercury thermometer.
I guess your water is about 24C or so, or your meter is way off.

no, his dev time is way too long. 😎

I think 40 oz is right, its just the developer, I figure that maybe 1:6 at 8 mins would be about right for box speed.

btw, I usually do 1:50 rodinal, tried acros tonight in rodinal at 1:100, the difference between the two dilutions is pretty intense, if you havent tried 1:100 you really should, Im really impressed.
