@NoCoNurse Correct. Rule of thumb is to halve the ISO for every decade past expiration, but a lot depends on how the film was stored. If it was in the freezer it’s probably good as new. If it was in the heat or moisture for 10 years you should lower your expectations.
@Gargron Thanks! Getting an opportunity to photograph permanently disabled raptor ambassadors today. Seems like a perfect opportunity to try the old camera out.
