_____________ are interesting because they keep some of their light-sensitive properties and can therefore appear to be washed out over time. This condition can be reversed, however, by returning it to a dark room.
Answer: A. Cyanotype
You didn't list the questions, but I'm taking the quiz right now.
Explanation: Cyanotypes are very interesting because they retain some of the light sensitive properties. And so overtime, they can appear to wear. However, they can also be reversed. So if it appears to become washed out, we can return it to a dark room for a period of time to regain the original richness.
Hope this helped! :)
