From the dawn of the film era in 1889 until 1951, the 35mm films projected in movie theaters were printed on highly flammable nitrate film stock. In addition to being hazardous nitrate decomposes, producing caustic gas that builds up between the layers of film. It also shrinks, eventually causing the emulsion to separate from the base, and in the later stages becomes sticky until the layers of meld into one black disc, ultimately crumbling into a rust-colored flammable powder. If stored improperly, nitrate film can even spontaneously combust. All of these properties pose significant problems to the archivists tasked with preserving film.

While preserving nitrate is difficult, it is also extremely important. It has been estimated that 90% of films from the Silent Era and half of all sound films made before before 1952 are lost forever.

Film preservationists have determined that the best way to store nitrate is to place it in a climate-controlled vault that keeps the film cool, dry, and well ventilated. Of course the storage area must also be built with fire safety as a high priority. As a result, there are few facilities that can safely deal with nitrate. The British Film Institute converted a nuclear bunker to store their nitrate. In the US, there are a few facilities. UCLA has a vault in Santa Clarita, and the MoMA has a facility in Hamlin, PA. One of the largest and best run nitrate facilities in the world is run by the Library of Congress (LOC) in Culpeper, VA, in a former Federal Reserve bunker.

I’m friends with a local film preservationist who has donated hundreds of films to the LOC over the last few decades, ranging from the hallowed work of Edison and George Méliès to campy sci-fi and westerns. He has also periodically lent out films for restoration projects, including Disney’s restoration of Fantasia. In 2009 I helped him coordinate the donation of about 200 nitrate items to the LOC, which constituted the vast majority of his remaining nitrate collection. For the next few years I gently encouraged him to give the LOC his few remaining prints, but he wanted to hold onto them.

I finally found my chance this spring. He read in the Vitaphone Project newsletter that the soundtrack to his print of Princess Ladybug (1930) had been found in Australia. The film was from the early sound era, before soundtracks were printed on the film itself. Instead, the sound was recorded on shellac records that were played in sync with the film using a Vitaphone player. As a result, you need both the records and the film print in order to reproduce the movie in its entirety. Because the image and the sound are so easily separated, many of the Vitaphone movies that still exist survive only partially. A film print may be sitting safely in an archive but the sound has been lost, or vice versa.

The discovery of Princess Ladybug’s soundtrack was the impetus he needed to make another donation. He wanted to send Princess Ladybug to the LOC to have it reunified with its soundtrack for the first time in over 80 years, and was willing to add a number of other prints as well. I put him in touch with the Nitrate Vault Manager, and volunteered to drive the films down to Virginia for him.

Below are the pictures of my trip:

Highlights include Charlie Chaplin's Work (1915), a mint fox newsreel showing Mussolini being hanged, the color segment from the first film to feature the three-strip Technicolor, Princess Ladybug (1930), a Vitaphone short whose audio was recently discovered, shot in the extremely rare Photocolor process, and the only existing print of Popeye Meets Sinbad, also Technicolor.

The shelving is designed so that if one reel ignites the fire is contained on that shelf, and the only other reel in danger is the single other reel on that shelf. The film cans are waterproof but air permeable, allowing the nitrate to off-gas. The room is ventilated so that the atmosphere in each room is completely replaced every half hour or so. It's also cold. The nitrate is stored at 35 degrees Fahrenheit, with a 55 degree acclimatization room. Any time a reel enters or leaves the vault, it's brought to the acclimatization room for one day. By changing the temperature in stages, they avoid letting condensation form on the film.

A fire activated linkage that closes off the booth in case of a fire. The linkage is made of a metal with a low melting point, so if a fire breaks out it will melt and the chain will drop, lowering a shield between the booth and the theater. Probably one of the only one of these still functioning in the world.

To give you an idea of how dangerous nitrate is, here’s a video of a single reel (about 20 minutes worth) going up in flames. You can jump to 3:45 to go straight to the fireworks:

Of course, this is film that has been purposefully set of fire. Nitrate was the standard for film presentation for more than half a century, and while projectionists had to be far more careful, accidental fires weren’t that common.

Doylestown in Kodachrome, 1938

Categories: Doylestown, Film, New Galena, Tags: ,

A few years ago I found a reel of 16mm film on the shelf at the County Theater. It contained a silent film of miscellaneous Bucks County scenery, and wasn’t that interesting. However, enclosed with that reel I found a page of notes referring to another 16mm film shot during Doylestown’s 1938 centennial parade (marking the incorporation of the Borough in 1838). With big plans underway to mark Doylestown’s 2012 bicentennial (commemorating when Doylestown became the county seat in 1812), I decided to track down the missing reel.

As it turns out, the film was last shown over 20 years ago by Closely Watched Films, the local film group that would eventually purchase the County Theater and convert it to a non-profit art house. I was able to find the owner of the reel, who still lives in Doylestown, and he agreed to let me borrow the reel (as well as three others) on behalf of the Doylestown Historical Society. His grandfather, Oscar O. Bean, shot the film in 1938. Census records show that he was a lawyer who lived on East State Street in 1930, and would have been about 57 years old at the time of filming.

I took the reels back to the theater to inspect them. First I opened the two small reels, labelled “Firemen’s Parade” and “Bull Fighting.” Unfortunately, they were water damaged when their storage area got flooded, and the film was coated in a white mold bloom. They’re probably salvageable, but they’d need work so I put them aside. The two larger reels seemed to be in better condition. While they showed some symptoms of age, they didn’t have the strong acetic odor of films suffering from Vinegar Syndrome, the chemical chain reaction that eventually destroys acetate film. I put the first reel on the rewind table, and as a picked up the tail of the film to attach it to the take-up reel, I found this magic word, printed on the edge of the film:

KODACHROME

The film was in color! And not just any color. Kodachrome is one of the best color processes in terms of archival stability. If stored correctly, it won’t fade or lose its color like other film stocks. And this film dates to 1938, just three years after Kodachrome was introduced. As a color film of Doylestown from this era, it’s surely one of a kind. Thanks to the Bean family, we can see the streets of 1930’s Doylestown in color.

The next step is to find funding to make a digital transfer of the film, which I hope to do through the Doylestown Historical Society. Once transferred, I’d like to somehow include it in the bicentennial events. A lot of the images are static shots, so I think it would be nice to incorporate them into a book of single frames. I’m imagining something like this book by Swiss experimental filmmaker Hannes Schüpbach, who selected images from his films and printed them accompanied by poetry:

Selected images from a 16mm film.

Below are a few photos I took with my cellphone. The reel containing the centennial event is entirely in Kodachrome. The second reel is home-made documentary of the history of Doylestown, and incorporates still images, maps, and reenactments, as well as Kodachrome shots of landmarks. It doesn’t really do them justice, but it’ll give you a taste:
