The following is a list of types of photography
and what should be done if they get wet. After this list is a general
explanation on how to go about their salvage and preservation (see section
"What to do and how to do it"):
Modern photography: This is your
priority list, as far as which type of photography needs to be saved first, if
you have to choose what to save from a disaster:
- Color prints, then
- Black and white prints, then
- Slides (transparencies) and then
- Negatives
This list is based on the fact that color
prints will be damaged by water the fastest and so on... then, of course, your
priority may be to save the photos of the kids first...
After the emergency situation has passed and
you have made sure that everyone is safe and as soon as you have gathered your
wits about you, your immediate decision is needed for the salvation of your
family’s photos:
It is imperative that the impurities are washed
out and that the film does not stick to itself (which it will do if it starts to
dry out). If you have more afflicted photos than you can take care of, I
recommended that after putting the film into a basin filled with cold
temperature (distilled) water that the help of a photo lab be sought out. Once
the film has been washed and stabilized and dried, it is important to store it
properly, even temporarily, such as in a sandwich bag or other archival
material.
Motion pictures should be rewashed by an
experienced film
processing lab within 72 hours. Till you can get the wet film
to them, fill the film cases with clean cold water or put into a basin of water
(change the water daily) so they won’t dry out and stick to each other. Once
the film has been washed, stabilized and dried, it is important to store it
properly, even temporarily, such as in a sandwich bag or one of many other
archival boxes from the suppliers at the end of the book.
Microfilm rolls: It is imperative that
the impurities are washed out and that the film does not stick to itself.
Because of the sheer volume of material to be handled, it is recommended that
after putting the film into a basin filled with cold temperature (distilled)
water that the services of a photo lab be sought out within 72 hours. Do not
remove the film rolls from their boxes: try holding the cartons together with
string or a loose rubber band. Once the film has been washed, stabilized and
dried it is important to store it properly, even temporarily, such as in a
sandwich bag or other archival material.
Old black and white prints on paper: Keep
in clean cold water (so they don’t start to dry out and stick together) until
you can do something. If they are going to sit in a basin of water for a couple
of days, be sure to change the water daily. The photos must be dried separately
within 72 hours. If you cannot properly dry them or get them to a processing lab
see the following section on how to freeze photography.
If you have other types of old photos but don’t
know what kind they are, call a photographic conservator immediately. Do not
pass "GO." Do not collect $200.00 If you know what you have, the
following list should help put the fear of God in you. They are all super
sensitive and the success rate for recover is low (in this case an ounce of
prevention is worth more than a pound of treatment):
Tintypes, ambrotypes, pannotypes and
collodion negatives are a first priority item! They need to be dried
immediately, face up. Do not put these types of photos in the freezer and do not
put them in a basin of water as this will destroy the emulsion. Be prepared that
the success rate for recovery is low, but this may depend on your care. Be
careful when handling the delicate glass supports.
Daguerrotypes need to be dried
immediately, face up. Don’t put them in water and don’t freeze them.
Nitrates with soluble emulsions need to be put
in the freezer immediately. Try freeze drying. Very touchy, be careful when
handling.
Let me emphasis again how important it is to
get the advise of a professional conservator who specializes in photography as
soon as possible. Please refer to the section at the end of the book on
"How to Find a Conservator."
