Not true. Do your homework. Even Wiki mentions Kodak's special, thin-
emulsion film. The lens which Zeiss helped produce for Hasseleblad's
lunar camera went on to become commercially available. The simplest
facts are often more interesting than creative knee-jerk cynicism and
paranoia. When you constantly wade up to your armpits in bull**** it
is difficult not to stain everything you post. Measure twice. Post
once.


The film used exactly the same plastic, coated with the exact same
photo-chemicals and processing. Thinner emulsion only improves some
of the details and it can otherwise increase the ASA/ISO speed of
recording photons in low light conditions, and that didn't even
measurable improve upon its dynamic range. Those NASA/Apollo missions
didn't need or having demonstrated any of those benefits.

The lens (all of them) was terrestrial standard optics with the exact
same coatings.

Your Semite run government lies to us so much of the time that you
think everything is exactly as it should be, as long as the whole
truth and nothing but the truth never gets out.

Kodak went along with them to the moon – in a couple of ways. We
provided three different types of film:

Ektachrome EF film SO168
Ektachrome MS film SO368 35mm film used in the stereo
Panatomic-X recording film – this was specially developed for use
on the moon

STORAGE
For consistent results, all aerial films should be stored under
fairly constant conditions. Kodak aerial films are “usually”
packaged in equilibrium with 40 to 50 percent relative
humidity. High temperatures or high humidity may produce
undesirable changes in the film.
Unexposed Film
Store unexposed film in a refrigerator at 13°C (55°F) or
lower, or freezer at -18 to -23°C (0 to -10°F), in the original
sealed container. If the film is stored in a refrigerator, remove
it about 2 hours before opening; if stored in a freezer, remove
it about 8 hours before opening. A sufficient warm-up time
is necessary to prevent moisture condensation on cold film—
otherwise, moisture spotting, ferrotyping, or sticking may
occur.
Exposed Film
Keep exposed film cool and dry. Process the film as soon as
possible after exposure to avoid undesirable changes in the
latent image. If it is necessary to hold exposed but
unprocessed film for several days (such as over a weekend),
it should be resealed and refrigerated at 4°C (40°F) or lower.
Before unsealing and processing exposed film that has been
held in cold storage, follow the warm-up procedures.
-
They didn't use this type of thin film, because the film they used was
wide thermal tolerant and rad-hard, as well as their color film was
impervious to temperature extremes, radiation and automatically
filtered out all weird and natural colors. Even pictures of Earth
were pastel and/or way underexposed.
