I think DDX is similar in formulation to Kodak Tmax Developer. Like DDX, Tmax has a standard dilution of 1+4, but it works great diluted 1+7 and 1+9. Kodak publishes times for Tmax 100 and Tmax 400 for the 1+7 and 1+9 times, and I have extrapolated from them to find 1+7 times for Tri-X and Delta 3200. Generally I have found that the time for 1+7 is about 1.5x the time used for the standard 1+4 dilution. I usually use it 1+7; I haven't used 1+9 in many years, though I remember it working well. I'd try your DDX at 1+7 at 1.5x the time you use for 1+4 as a starting point.
I like f76+ aka arista premium. Despite the name it's more chemically similar to xtol/ddx than d76. Inexpensive as well. I like it for the tmax films
Two things I think is important to remember here:
1) Is that any time you start with a fresh recipe, you normally need to fine tune exposure, development, agitation... (Extra time or agitation may have solved Roger's mid-tone complaint.)
2) Is to understand how important the roll in question is, can you risk that roll in an untried recipe.
Yeah - these are rolls I can't experiment with, so I'll probably stick with DDX 1+4 - at least for the D3200 rolls. And probably the tri-x, although I really like tri-x in perceptol, as well.
I'm interested in the arista - I've never used it before. So far I've used perceptol, Microphen, DDX, and ID11. I wasn't thrilled with the ID11, but admittedly didn't prep it the best - pretty sure I was under temp with it.
Thanks all!

I tweaked the time for preferred overall contrast. I think any change would have affected that too much. Results weren't bad I just preferred the results with T-Max developer slightly stronger. As seldom as I get time to do darkroom work I'm not worried about the cost of developer for the small amounts I use.
Perceptol and ID11 work very well in most circumstances, although I use Kodak XTOL. I've not got better results with liquid concentrates although started off with DD-X about 10 years ago and achieved fairly good results for a beginner so the developer must have its qualities. In the UK we have a product Fotospeed FD-10 which dilutes 1+9; I wonder if this is similar to the F76+ developer?

It might be! Since Clayton makes Freestyle's Arista Premium Liquid for them it just might be they make Fotospeed FD-10 for a new label. The starting dilution is 1:9 also. Do you have any starting times for some films so we can compare? If times are the same then it's cinch to be Clayton F76+. I like Xtol and DD-X too, with a slight edge going to DD-X, but you're splitting hairs on that match. JohnW
I switvhed to self mixing not based on cost butbased on increasing knowledge and darkroom fun.

Looking to be a chemist when you grow up?
It is real practical with a cheap mini scale resolution of 0.01 gm, one even do any phenidone dev, the acid fix and hypo clear as well, restrainer for warm or cold prints. The only problem is should I use distilled water or not, (havn't yet)?
Yes, and I regret not having paid better attention in chemical class, but at that time, my brain was side-tracked by body chemistry and Helmut Newton,which bothturned out to be a major photographic influence for me.
I use distilled water(can't hurt, right?)but my main problem wasless than pure sodium sulphite.In my case, it must have contained metal ions, which the development activityand I got nothing but clear film.::confused:
