Hyperspectral Photography
Abby Brack Lewis
Our friends at American Photo have a great feature up today about hyperspectral photography, a technique that takes advantage of the fact that photographs often capture light beyond the visible spectrum. Using the technique, you can peel back history--and see what lies underneath pages that have been blacked out, erased, or written over. It's already leading to new discoveries about Lincoln, Archimedes, Sophocles, and more--what'll be next? Read the full story at American Photo.
