Another look at the ways a photograph's deterioration can have a striking effect on its image. From the 1850s to about the 1920s, the majority of photographic negatives were made on glass, coated with a collodion or gelatin emulsion. Though glass negatives capture a lot of detail, they are also bulky, heavy... and breakable. Broken glass plate negatives are not uncommon, particularly in the collections of archives where image content is considered especially important. Digitization has been a terrific boon for these broken plates, allowing the images to be put back together and viewed in a way that often is no longer possible another way. The creation of a digital positive is sometimes especially interesting in these cases, as the missing parts of the negative end up rendered black, creating an interesting visual. The cracks themselves can have a striking effect on the image, breaking the illusion of the photograph as an unmodified glimpse of reality.
