Would like to hear opinions on the technique of mounting prints on aluminum plates. I know of several photographers doing it and like the idea of using a pure material instead of plates made of plastic or plastic/wood sandwiches.
However I am still uncertain regarding the long-term stability. Isn’t aluminum oxidizing extremely fast and aggressive and wouldn’t the oxides in some way diffuse into the print?
FYI here is a 3 years old threat discussing mounting on aluminum but not touching archival issues at all.
