Did you use T-Max or T-MaxRS? I don't know if both are
available any more. RS means replenishing system. if you
replenish the developer it will maintain pretty constant
strength. However, you can't go on forever because eventually too
much bromide and other reaction products build up. The streaking
sounds like accumulated bromide.
If you just keep using the same developer over and over it
will loose strength and quality pretty quickly.
I don't remember for certain but think Xtol can be
replenished the same way as T-MaxRS, that is, using the working
developer rather than a special formula as is the case with D-76
or DK-50. Those are much harder to get consistent.
Unless you process a lot of film I think using diluted
developer as a one shot will give more consistent results.

Hi Frédéric,
I used to use Kodak TMax Dev with FP4, my favourite of all modern films, and would try to keep it going for at least 10 rolls at a time. I started to experience problems with permanent streaking through the negatives that, in the end, I couldn't positively identify with any particular part of my process, particularly the developer, but TMax did work nicely when it worked. I'd assert that I had far more success with it than otherwise. In a determined effort to finally stop ruining rolls of film, though, I opted for doing one-shot developing, using Kodak HC-110 with the B mixing solution, and I've found that to work quite well.
Best wishes,
Dave

Good morning
Looking for a substitute dev for DDX
I like this dev with fp4 & hp5
But tend to waste it, as I never end up using it all in time.
Something with good keeping properties…
Thanks in advance
Frédéric
