What is the best way to travel with 4x5 B&W film? I assume that unexposed film is best left in its original box and loaded into the carrier shortly before use. Loading by way of a dark bag. Then what, after exposure? Do you simply reverse the process and put the exposed film back into an original film box or is there some other preferred way to protect the film?

I use ZIP-LOCK bages for both & then a ICE Chest
to keep them from my 95* t0 108* temp because
hot is BAD
