I had a partial roll of film left in my Kiev, so I went shooting one day to finish it out. Thought it was Delta 400, but when I took the spool out, it turned out to be Delta 100.
Oops.
Since I had an untried bottle of DDX at home, I figured this was a perfect roll to test it out on. I souped it up at what the bottle recommend for 100, which was 12:00 @ 68F.
I didn't expect the frames I shot at 400 to turn out, but to my surprise, they did. Turned out very well in fact! So well, I'd almost have to say Delta 100 has the latitiude of a color negative film. See for yourself. All three of the attached were shot at 400 and are straight from my scanner. Haven't been retouched in any way.

Pretty neat that your frames were saved by lattitude. Why not post a few of those shot at 100 for comparison's sake?

That's quite a finding.
Of course the 100's shot at 100 are better. But since you didn't even "touch up" the mismatch it's almost a given that with a little PS "tweaking" you could just about compensate for the 2 EV (?) difference.

Glad they turned out OK, Captain. DDX is a speed increasing developer usually good for about 2/3 stop over box speed IME. So (say) ISO 160 at recommended time/temp, thus 400 is just over a one stop push. I'd expect lack of shadow detail with that level of underexposure, but in flat lighting conditions it should be easily possible.

So you shot at 400, but dev'ed as if at 100? Then your results are intriguing...
However...and I say this a lot so hopefully those that find me too repetitive have just tuned me out but...how are you metering? Perhaps you're actually overexposing and bringing your EI closer to 200/160 ish, which is what you'd get out of DDX anyway.
I don't think one can talk about latittude without knowing a real EI in a particular developer based on your process techniques with controllable metering.
But nice results.
