nice ir shot. Makes me want to go shoot more HIE.
I concur with Don on the pmk. I develop a little longer, but use a little cooler temp. It comes out in the wash.
I would suggest not using your in-camera meter. It isn't calibrated for IR. Follow Don's suggestion: on a sunny day, through a red 25, f11 and 1/125s. Bracket slower if you feel you need to, like f11 and 1/60s, but it's generally spot on.
