Something I haven't tried much of is shooting expired Kodachrome. I shot and developed an age unknown but genuinely old K25 back in 2020, (shot at iso 6, developed 6 minutes in caffenol, the cassette had no dx coding) and got decent but a bit underexposed results, but never really tried again. I've currently got an age unknown, Kodak select Kodachrome 200- so I'm assuming this would have expired sometime in the 2000s, probably should shoot it at ISO 50 if I follow standard CN expired film over exposure rules, and I just picked up a 1975 expired K64- which I'd estimate should be shot at about ISO 3. what do you all think? should I use standard CN overexposure rules for Kodachrome film, or does Kodachrome deteriorate differently from cn and ct films?
and as for developing, I haven't decided if I'm going to try caffenol again, or try to find Hc110 development times.
