Very nice! I just did a few infrared photos today. Still have a few shots on the roll. I hope mine are even nearly as good as this.
My Dad was a big infrared fan - did a lot of work that way. I just loved it. Glad you're working with it.
I rate it at 50 ISO and allow 5 extra stops for the filter and bracket around that. I soup it in Rodinal Special at 1:15 for 13 minutes with agitation each minute.
