...Photographs should be protected from extended exposure to intense light sources. Limit exhibition times, control light exposure, and monitor the condition of the photographs carefully. Prolonged or permanent display of photographs is not recommended. Use unbuffered ragboard mats, and frame photographs with archivally sound materials. Use ultraviolet-filtering plexiglass to help protect the photographs during light exposure. Reproduce vulnerable or unique images and display the duplicate image; in this way, the original photograph can be properly stored and preserved.

Disaster preparedness begins by evaluating the storage location and the potential for damage in the event of a fire, flood, or other emergency. It is important to create a disaster preparedness plan that addresses the specific needs of the collection before a disaster occurs.

The location and manner in which photographs are housed can be the first line of defense. Identify photographic materials that are at higher risk of damage or loss. Remove all potentially damaging materials such as paper clips and poor-quality enclosures. Store negatives and prints in separate locations to increase the possibility of an image surviving a catastrophe. If a disaster occurs, protect the collection from damage by covering it with plastic sheeting and/or removing it from the affected area. If using plastic, make sure not to trap in moisture as this could lead to mold growth. Evaluate the situation and document the damage that has occurred. Contact a conservator as soon as possible for assistance and advice on the recovery and repair of damaged materials.

PS .If your photograph requires special attention or you are unsure about how to protect it, you should contact a conservator.To search for a conservator near you.

Hundreds of millions of photographs have been lost over the years to natural disasters, wars, and the age-old urge to clean house. So there is something special about every old photograph that's survived. Someone decided to make it... someone else, to buy it... and a lot of someones decided to keep it over the years. Whether you're the caretaker of a treasured family album or a collector who has searched out the classics of photography, it's important to preserve and protect the images you value. Fortunately, there is new information about what to do and what to avoid. And there are specialized products available to help.

Using the pinhole technique is one of the most authentic ways to record photographic images.
The technique is based on the principle of the camera obscura which is centuries old. Basically it's nothing more then a lightproof box with, in the middle of one side, a tiny little hole instead of a lens.
The light works its way through the pinhole right into the enclosed room and that is how at the opposite side of the pinhole an image appears which is upside down. We can preserve the image by putting material which is sensitive to light at the side where the image shows up and develop it after exposure.
However photography was only invented in 1839 the principle of the pinhole has been known since ages. As early as the 4th century B.C. this phenomenon was mentioned by Aristotle in one of his writings. Light falling through a small opening between the leaves of a tree gives a perfect projection of the sun on the ground. Even though the opening between the leaves has a shape which is irregular and is not perfectly round, yet the image on the ground is. Aristotle could never explain this.
This happened much later in the 16th century, because scientists were
frequently experimenting with the pinhole technique.
All this started in the 13th and 14th century.
Different scientists used the pinhole principle in order to study the eclipse of the sun and the wave-lenght of the light.
In the 15th century the technique was used by artists as an aid to make their drawings.
Leonardo da Vinci was the first to hit upon the idea of using a box for it.
He described how
one could get an image on a transparant screen and trace it on the outside. But it was not until the 16th century until this idea had come to its full development.
Lenses excisted in this century but people still used the pinhole principle to study the sun.
Scientists often stared through their (pinhole)telescopes and looked directly into the bright sunlight.
As a result they suffered from blindness. Just to spare the eyes, scientists started to use a camera obscura (darkroom) so they could study the projected image of the sun instead of looking at it directly. From this moment on it didn't take long before artists started to use the camera obscura frequently.
In the 18th century the principle of the camera obscura becomes generally known and even travellers are starting to use the phenomenon. They are using the portable version of the camera obscura just to trace the things they see during their journeys. These "snap-shots" are pasted into their book of travels and kept as a souvenir.
If people didn't possess a camera one payed money to enter a permanent camera-room. Here the surroundings could be seen by means of a rotating mirror. The moving images were projected on a white table.
All this was very popular until the official invention of photography in 1839.
From this moment on there was no need to trace images anymore and the pinhole principle was completely forgotten.
Until the most famous pinhole picture of that time showed up, a photograph of 1890 from George Davison, The Onion Field. This picture won the highest price at the annual exhibition of the Photographic Society in London. This particular picture was the beginning of the popularity of the pinhole camera which would last for several years.
There were some american companies that put pinhole cameras on the market and even a
special pinhole disc that could replace the lens of a regular camera.
From the 20th century the pinhole camera lost popularity. Making images with a camera like this was considered to be inferior. The reason of this was most probably the growing need for speed and mass production of photographic equipment. Finally the principle was only used to teach people the basic techniques of photography. Between 1940 and 1960 the pinhole technique was completely forgotten.
From 1960 until now pinhole photography is being used sporadically by artists.
