A couple years ago I got a 28 year old can(50ft.)of High Contrast Copy film out of my freezer(can was getting pretty rusty),and loaded it into cartridges,then re-froze them. I tested one of the rolls.I could see no difference from the same kind of film of nearly 30 years ago.So,I think you or anyone won't live long enough to see the difference between frozen B&W and color.....

I would try Rodinal 1:50 22.5 min.,68 degrees.This is from an old Rodinal data sheet.My experience is that your negatives will be very hi-contrast without shadow detail so try printing at the lowest contrast you can.Don't expect much,good luck. p.s. D-76 1:1 for 22min.@ 68 degrees should work as well.

Spot meter horizontal snow that has no glare from the sun on it and place it on Zone VII.

I would use a ZoneII pre-exposure.This will noticably increase shadow detail.

I've been using Pentax 35's since 1970 and tested many lenses with my "Modern Photography Lens Testing Kit"and read the lines per mm with a microscope at 50X.The story in a nut-shell is this:without testing nobody could tell the difference between 11X14's taken with any 50/55mm Pentax lens.But since you ask here's the dope(lenses of my own at sharpest f-stop and area):Super Takumar 55f1.8(88 l/mm center&edge@f8);Super Takumar SMC 55f1.8(80 center&edge@f8&11);Pentax 50f2(64 center,72 edge);SMC Pentax 50f1.7(88 center&corner@f5.6);SMC Pentax 50f1.4(Modern's test score 80 center f5.6&8,63 corner f5.6&8),also have a SMC Pentax M Macro 50f4 that I've not tested but it makes tack sharp 1:1 slide copies.The 55s were screw mounts,the rest are K-mount.If I shot exactly the same photo, with say, my LX on a rock solid tripod,same f-stop(5.6,8,or11) and shutter speed,only changed lenses;no one could see any difference, period. That's my dope.
