I rate TMX at 100 in Microphen 1+1 or 1+2 processed at 25C.(posted 8162 days ago)These days I mostly use my formula (found in past thread here or on my home page) for TMX also rated at EI of 100/21. I get noticeably sharper images this way than in Microphen.
If you want to try somewhat simplified way to similar effect, try D-76 1+4 with additional borax.
HC-110 does not seem to produce apparent sharpness with TMX no matter how you dilute it. If you want smeared metallic feeling, it's useful though.
