I like Microphen 1+1 to 1+3 for TMX, because it makes reasonably sharp images with good shadow separation even when I shoot at EI 100. The grain is not as fine as with D-76H 1+1 or HC-110 1+15 from stock. HC-110 1+15 makes very smooth, fine grain image which I don't like much but sometimes useful. One thing I don't like about Microphen-TMX combination is that it seems to compress midrange.(posted 8281 days ago)I'm surprised that no one so far suggested DK-50 or buffered FX-1 type formulae. I'm still doing some experiments, and I'll post my formula and time when my experiments are done.
