Fuji Super HR Microfilm and TD-3 developer

[fatboy22]

Anyone have any experience shooting Fuji Super HR microfilm for pictorial images? Kind of like Kodak tech pan.
Trying to process in my Jobo with TD-3 developer , not sure what to rate it at. Tried a test exposing at 80 iso. Developed for 11 minutes, 75 degrees. Not much there very thin.

At ISO 80, you're probably way underexposed.

Here are my notes from when I was playing around with Agfa Copex:

A formula from John Brubaker that worked well with Agfa Copex rated at ISO 50 - though it was best to avoid high contrast subjects:

Mix a Sodium Sulfite solution of 2 oz Sodium Sulfite to 1 liter of water
Mix 2.5mm of HC-110 (concentrate, not stock solution) to 200ml of Sodium Sulfite solution
Develop for 6 min at 68 degrees F with agitation every 30 seconds.
​

As they say, YMMV.
