Yeah, I could just put in a search and get about a billion responses but I wanted to ask the forum members if they have a preferred dilution and time. For Tri-X I’ve been using HC-110 Dilution E (1:47) and it works well. I do have a small bottle of Rollei One Shot R09 that I use at 1:25 for seven minutes per the bottle instructions. I haven’t tried the 1:50 for fourteen minutes yet and I know D76 or Xtyol are preferred but I’m not interested in having a gallon of developer sitting around for my single reel 250 ML tank. The R09 gives a bit different look than the HC-110 and am on the wait list for Adox Rodinal. The one time developers work for me, having a small house and only exposing a few rolls a month. I’m more interested in a negative that scans well, since with no darkroom, printing isn’t a priority. Any suggestions are always appreciated.
I used Tri-X developed in Rodinal for a decade. 1:25, 1:50, 1:100, normal, semistand, stand, EI200, EI400, EI800, EI1600.
Only if you're interested in very present, sharp and big visible grain, Tri-X in Rodinal is a good idea for scanning.
The very interesting tone of Tri-X well used on silver paper, vanishes after scanning. The image becomes a different thing. Of course that different thing can be used: it can have any tone, and any grain, using software.
If I had to do it for scanning, I'd use 1:100 with 6ml for a slow/soft development to control sun, leaving soft scenes soft on negative: Tri-X is dynamic enough to print well soft scenes using higher contrast MG filters.
Be prepared to hear some experts tell you I'm wrong: I can only believe my eyes and my fiber MG paper... IMO agitation plays a huge roll when we use Rodinal. Of course, that's more critical and visible with strong dilutions. Indeed very little agitation is required. Apart from very slow and gentle, try one inversion every second or third minute, and see. And in my tests and use, staying at 17-18 degrees Celsius was the best way to do it with Tri-X.
You can use D-76: some months I don't even do a whole roll.
Even just to see how well it works, you can use -and throw- 240ml of D-76 stock for every roll: that's less than one buck per roll, and it's the best Tri-X I've seen. It's not true grain gets mushy or images become less sharp.
But if you never do the same scene in Rodinal and in D-76 stock, you will never know.
If all the roll is overcast, stock is great, but if you have any sunny scene, 1+2 is better.
That's why 1+1 is recommended as an everyday compromise, but the other two options are better for each type of light.
Good luck!
