TMX in Reagent III
Some highlight blocking is definitely apparent in the V750 Epson scan at the "automatic" setting. Like a number of other slow to develop emulsions, TMX does appear to have that tendency to block up the highlights with this mix, Pan-F much less so, and Efke somewhere in between. I think we can fine tune it later, just watch out, maybe by a half or whole stop, if you are experimenting as we are today with the published mix.
Nice twisty things on that plant.
1. 8 ml HC-110 USA concentrate
2. 25 ml household ammonia(soapy is OK)
3. 5 ml Ilford Rapid Fixer
4. Water to make 128 ml
If you can measure the pH with a test strip, confirm it is at least 8.5, and if not, add a little more ammonia. Use the Ilford fixer as that has ammonium thiosulfate.
HC-110 is like a thick syrup. Measure it out in a larger container, then dilute it with the ammonia which will dissolve the syrup. Process TMX for 10 minutes at 75F. This works best when warm. Wash the negative in plain water for a few minutes if you can. The water should not be cold or hot. Then hang it up to dry. If you used soapy ammonia, you won't need any Photo-Flo, as the residual wetting of the soap is still present.
This could hardly be easier. Don't worry about the pH or the washing, Just mix it up and you're there. I would recommend you try this with Ilford Pan-F ISO 50 too, as the result is quite nice. See here.
