Welcome to March to the Moon. This website serves as a digital repository for the hand-held camera photography captured during the Mercury, Gemini, and Apollo programs, which flew between 1958 and 1972. NASA team members at Johnson Space Center scanned the films in an ongoing effort to preserve, share, and commemorate some of the greatest historical achievements of humankind.

Following the completion of each mission, master duplicates were produced and the original flight films were placed into archival storage. These galleries are digital scans of the original films – and the first instance in which they have been provided on the Internet. Select a program below to begin exploring these amazing photographic moments in human history.

This is a nice repo of Space pictures. Thanks for sharing the link.

You're welcome.
I was glad to come across it, too!

hmm...

For information about how to distinguish raw film scans from processed digital image files, please view the image processing section above.

But I don't actually see an "image processing" section.

I think it was referring the same section where those words were located. Other than that there wasn't any specific "image processing" section.

Raw Scans
Digital scans of Mercury, Gemini, and Apollo flight films by NASA (Metric, Panoramic, ALSCC, 70mm Hasselblad, 35mm Nikon and Stellar) in their raw (unprocessed) form are in the public domain and as such are covered by NASA usage policy for still image and computer files (see here).

Processed Images
Arizona State University retains the rights to any derived products (such as post-scanning processed digital images and movies), in part and in whole with a non-exclusive, non-transferable license. ASU hereby grants

The "About the scans" section of the Apollo film archive has an image processing paragraph, but I think it's actually in a section named "File Format Notes" where you'll find the most relevant information about how to distinguish between image type:

The raw, unprocessed scans are provided as 16-bit TIFF files. The processed images are provided as a large 16-bit TIFF file and as 8-bit low-, medium-, and high-resolution PNG files.

Also, I now noticed that one of the download options in the gallery is clearly labeled, "raw", so it's actually pretty easy to tell which is which... It's disappointing, though, that the processed files are not in the public domain. C'est la vie.

Seems like NASA's photos are the same as mine. For every good photo, there are a hundred that are low-quality or mundane subjects. In one of the later Apollo missions, I came across a series of shots of an astronaut shaving.

Haha! I noticed those same two things. Surprising that the photos are not in the public domain. It seems to me that the reason is that the university has control over the film. Weird.

I kind of like the photos of astronauts doing something of little consequence.
