Maco 820 IR Aura

[TheFlyingCamera]

I pulled some rolls of Maco 820c Aura infrared film out of the fridge yesterday. It has been sitting there for years, literally... it outdated in 2007. I shot two rolls of it yesterday afternoon as a test, to see how much base fog and how much IR effect I would get with an R72 filter on my Rolleiflex. Good news - the film is now hanging to dry in my darkroom, and it appears to still have relatively normal sensitivity - I shot it based on recommendations I saw to use between ISO 3 and ISO 1. The frames shot at 1/2 second at f16 were a little thin but printable, and the 1 second at f16 shots all look very good. There were some I took under the forest canopy and just winged it, giving between 30 seconds and 60 seconds (the Maco 820 has HORRIBLE reciprocity failure), but that was too much - I could have gotten away with 8-15 seconds for those same shots.

it doesn't surprise me that your film is "sti;; good" best of luck with your printing!

IR can be really intense in forest conditions. I was caught out by that when shooting in quite dull conditions in a wooded area. There was far more IR than anticipated and some very dense negatives. They are still printable, however, although they need long exposures. I have had reasonable results from negatives that look totally black.

Nice to know that Maco Aura has a life well after expiry date. Just a pity that it's a tripod job almost every time. Based on your figures, I might just about get away with a fence post as a substitute tripod, a 28mm lens and f4
