We often use
the word photograph when referring to the positive image on paper
that is a familiar fixture in our daily lives. In reality, a photograph
can be one of many processes in which light-sensitive media are
employed to create a visible image. |
| The
prevalence of photographs allows us to forget that they are potentially
fragile objects that can be easily damaged by careless handling,
improper storage, and exposure to environmental influences such
as light, humidity, and temperature. |
| In caring for
a photographic collection, it is important to know that various
components create a photograph. The interaction of these components,
with each other and with their environment, has a lasting effect
on the longevity of the image. |

Most photographs consist of a final image material, a binder layer,
and a primary support. The final image material - commonly silver,
platinum, organic dyes, or pigments creates the image we see.
The binder layer is a transparent substance albumen, collodion,
or gelatin in which the final image layer is suspended. The binder
and final image material are applied to a primary support, usually
paper, glass, metal, or plastic. Although many photographs have
this three-part structure, individual images may have additional
components. For instance, applied color or coatings and original
frames or cases need to be considered as part of the photographic
object.
