Considering the state of the cameras I wouldn't be surprised if the film was at least partially exposed to light when they removed it from the ice.

I don't know the answer, but there's a famous lost camera owned by a team that perished on Everest before Hillary/Norgay successfully climbed it. It's possible that the camera contains proof of an earlier first ascent: https://en.wikipedia.org/wiki/George_Mallory#Reaching_the_su...

Kodak has published instructions for how to protect the camera and develop the film, if it's ever found: https://web.archive.org/web/20130303001517/http://www.veloci...

I'm guessing you'll need to watch the upcoming documentary to find out. Or wait for an article post documentary.

Even if the film was unexposed there is still corrosion and water damage.
