"Each film magazine would typically yield 160 color and 200 black and white pictures on special film. Kodak was asked by NASA to develop thin new films with special emulsions. On Apollo 8, three magazines were loaded with 70 mm wide, perforated Kodak Panatomic-X fine-grained, 80 ASA, b/w film, two with Kodak Ektachrome SO-168, one with Kodak Ektachrome SO-121, and one with super light-sensitive Kodak 2485, 16,000 ASA film. There were 1100 color, black and white, and filtered photographs returned from the Apollo 8 mission." -- NASA
The project started in 2009, on the 40th anniversary of the Apollo missions. The film had been stored for 40 years in freezers at zero Fahrenheit (-18 Celsius). After carefully bringing the film to room temperature, a Leica scanner was used to obtain 5 micron level of detail (around 5,080 ppi).
Browsing the photos on Flickr are much lower resolution, but the high resolution scans are available for downloading or sharing. LIke almost all works by the US Federal government, as enshrined in the Constitution, the photos are public domain.
