RE: [APML] Vacuum baking

George, well, baking in a vacuum is like heating a thermos bottle. Radiant
IR still gets to the film however and you can expect up to a 2x speed
increase until the film rehydrates.

Part of the hypering process involves vacuum baking to remove moisture
and impurities from the film.
For films that react well to hypering, would just vacuum bake portion of
the process provide any improvement to the film? Or would I just be
looking for trouble with film creep due to moisture ingress since I
don't have a nitrogen or dry air purge system on my camera body?
