Like D76 or Microdol straight. Not 1:1 or 1:2 or 3. And even more so if you poured it back and replenished it and constantly re used it. All that eating away of sliver and replating it back on your neg could be a nice metaphore for an anti aliasing filter effect. Compare the results of someone doing this straight replenishing thing with an Olympus OM1 24x36mm: To someone using a high acutance developer with an Olympus Pen F, FT, FV half frame 18x24mm. And you have Leica M8 against the modern digital world.
