If we are to be smart about this image stability issue that I have never encountered with Pan-f, it seems to me that over exposing the box speed by one stop would be a proper cure.
There is no way that double the light on film will fade away in a serious way. Doubling of light is a lot, to begin with.
Also, as a sidenote, I believe that iso 50 is already underexposing it. Pan-F is not a 50 iso film
As a second sidenote: would any film keep a good latent image of an underexposed exposure? Answer is: No.
Especially if you use a reflective meter, chances are that you are actually exposing this native iso 25 film at 100 (camera set at iso 50 and add the camera’s reflective meter natually underexposing by one stop). This is deadly for any slow film, as slow films are already extremely intolerant. Always has been the case. Look at tmax, and the various old slow speed films.
Expose Pan-f @ iso 25 with a proper incident light meter and you will never, ever, run into any kind of problem.
Beautiful film.
