Is DD-X developer ok to use for Acros 100? Also, I would like to control the contrast. Can someone point me to a development time chart that relates to the amount of contrast?

    \$\begingroup\$ In my opinion, this is going to be opinion-based. You could avoid that by asking instead what properties of DD-X interact in what ways with Acros (but you might also need to specify whether you mean original Acros or Acros II). \$\endgroup\$

    \$\begingroup\$ Agree w/ @ZeissIkon. Also, bear in mind that the negative is just an intermediary step to the final print. When you say "control contrast" are you trying to lower it because you shot a particularly high contrast scene? Worried about blocking your highlights? What are you going for? Also, will you be scanning or printing in the darkroom? \$\endgroup\$

  • \$\begingroup\$ Thanks for your input. I might go either way with the contrast. Some times less and sometimes more. Maybe it doesn't matter since I will be scaning to digital. I might try my hand at pushing film just to experiment. \$\endgroup\$

It should be (more than) fine, yes. Massive Dev Chart and FilmDev both have some suggestions for this particular combination (the latter with sample photos). Plus, there's a lot of discussion on various forums, if you google "acros in dd-x".

As for control of contrast, you could try to extrapolate from the Acros data sheet, which gives characteristic curves for various developers (though ultimately you'd have to run your own tests to find out how the film behaves in DD-X). Looking at the G-bar-against-time plot in section 14 of that document, a reasonable first guess would be to expect an increase of 0.1 in G-bar for every added 2 minutes of development time (in 20°C).
