English: NASA hired Barbara S. Askins, a chemist at NASA's Marshall Space Flight Center, Huntsville, Alabama, in 1975 to find a better way to develop astronomical and geological pictures. In 1978, the Association for Advancement of Inventions and Innovations named her the National Inventor of the Year for her invention of a process that restored detail to underexposed negatives that would otherwise be useless. In 1978, Barbara Askins patented a method of enhancing the pictures using radioactive materials. The process was so successful that its uses were expanded beyond NASA researchers to improvements in X-ray technology and in the restoration of old pictures.
