The Greg Mironchuk method of TMX developing as outlined on his page
at http://www.mironchuk.com/hc-110.html states that longer development
times with dilute developers at higher temps and minimal agitation produces
negs with good shadow detail without blowing out the highlights.
The theory is that developer "poops out" faster in the areas of greatest
density while continuing to develop shadows.
This seems like an ideal method to limit contrast without affecting speed
while also minimizing the potential for film scratching due to agitation.
Development times are not that much longer than standard HC-110 times @68 degrees.

Can anyone say why this method is not more common as a standard tray method
for development for all films? I have done about 20 negs this way and it certainly works well so far. I am also using a night vision monocle which helps a lot too as
you can easily see when the negs are cooked to perfection.
