Today was my first attempt at IR film in 120. I chot some scenics out in the Los Padres National Forest. I did about 1/2 of the exposures at the suggested exposure of 5.6 @ 1/60th or the equivilent, and the other half with my meter set to iso 50 plus compensating for thr red 25 filter on my lens.

My film just finished fixing, I decided to take a peek prior to washing it. Zero exposure on the film, nada, nothing, zilch... except for the side markings.

Film is Konica 750 that had expired in 2002, but had been in cold storage. Dev was Hc110 dil B 7 mins at 20c.

What the heck happened?
