It's not a thread about D-76 & Xtol but Sandy if you'd tested Tmax in D76 and Xtol in a 35mm camera, with high level lenses then there's an unmistakeable difference in sharpness & resolution between the two.

Ian,
Well, I was just answering a question, not attempting to hijack the thread.
But, I stand completely by my statement that sharpness is determined more by developer dilution and type of agitation than by the developer itself. As for resolution, I compared D76 and Xtol with a high resolution chrome on glass target several years ago, and the tests took a lot of time and were done to the best of my ability in an effort to be fair and objective. I compared Xtol with D76, and also included PMK and Pyrocat-HD. I also tested four different films, two traditional emulsions films and two T-grain emulsions.
My results showed virtually the same resolution with all four films comparing D76 1:1 and Xtol 1:2. Pyrocat and PMK both gave an increase of about 10-15% in resolution compared to D76 and Xtol.
What was not mentioned earlier is grain with Xtol is finer than with D76 and this may be what makes it appear sharper in 35mm work.
