Photographic conservation Photographs are usually stored in libraries and annals all over the world, but photographic management is still a fairly new subject, for the most part in the area of chemical treatment. Nowadays, we can prolong a lifespan of a photograph by simply good care and practice and using a fairly decent storage conditions. In this essay, I will talk mainly on the guidelines on handling, storing and basic techniques. In an ideal world, a photograph should not be touched at all! Clearly this would defeat the purpose of an archive as a worthwhile resource, but we can still manage to keep damage to a minimum if we take precautions and careful handling procedure. Below are some of the recommendations on how to handle Photographs: 1. Before examining photographs, always use clean hands, and if possible wear gloves to avoid leaving fingerprints and dirt on …show more content…
Mechanical wood pulp papers 4. Kraft papers 5. Old photographic product boxes Filing cabinets should be made of metal with enamel coating. Old wood may be safe but all new wood must be avoided, especially if it has been bleached or freshly painted. Cellulose nitrate film, which was produced mostly between 1889 and 1939, can be very dangerous. Nitrate film in archive should be isolated and placed in a cool, dry, well-ventilated area. It is highly inflammable and can ignite in certain conditions. The biggest risk is when its placed with sizeable amounts of old, densely packed collection and the film should never be near a heat source. If cellulose nitrate ignites, it produces gaseous products that catalyze further decomposition and could affect nearby materials. It can also burn under water, it has a highly toxic fumes, smoke and heat are formed very quickly. If the building is insured, the insurance might prohibit the use of cellulose nitrate. There are also other environmental factors that could affect the preservation of photographs: 1. Temperature 2. Relative humidity 3. Air purity 4.
B) Briefly describe each method, including the specific types of scientific tools and equipment used. Modified Mercalli Intensity Scale:
Corrosive to eye contact and skin contact. If there is contact rinse the area with water for 15 minutes. Silver Nitrate: Very Hazardous in case of skin contact or ingestion. Prolonged exposure results in skin burns, ulcerations, and respiratory irritation.
Air temperatures and seasons that the past and current experiments were conducted in may have also altered the levels of saturation. As past results were conducted in cooler air temperatures of 20.1 to 21.4 degrees
Determining the Identity of an Unknown White Compound Maxwell Yurs Group Member: E.B. Floersch, Alexander Medina, and Masih Horri College Science and Engineering University of Minnesota, Minneapolis October 12, 2014 The experiments that were completed were used to determine the identity of an unknown white compound to allow for proper disposal. These experiments included flame tests, pH tests, and conductivity tests. After each was completed, it was found that the identity of the white compound was Sodium Nitrate.
A Photograph is one of the ways to preserve memories, event, and the moments. We take pictures for memorizing the moment or just want to see it later. Before camera that print out the photograph realistically, many cameras and print out methods developed for several decades. Camera Obscura, Daguerreotypes, calotypes, and Camera Lucida. Photographer used darkroom to print out a photograph.
Chemical Safety and Hazard Investigation Board, 2013). Moreover, the company had a practice of storing fertilizer grade ammonium nitrate near combustibles. This practice contributed to the rapid progression and intensity of the fire (U.S. Chemical Safety and Hazard Investigation Board, 2013). This was a critical oversight of the company. WFC’s omission to file proper toxic materials disclosures with county stakeholders, as well as, being negligent in its storage practices, and lacking a fire detection system to alert local emergency responders, exemplify the organizations futile
Materials: The materials that I will be utilizing during these experimentations are three to four ice cubes, one cup for measuring, six unblemished cups, one stopwatch, one hot water source, three tablets of Alka-Seltzer, one thermometer that measures from negative
The decorations had not been treated with any type of fire retardant spray or anything of that
A photograph can mean so much to different people, but it’s ultimate purpose is to capture an important moment in someone’s life and be able to hold onto a physical copy of a memory. Photographs enact a certain nostalgia for the past, the good times or perhaps an important person or location; it’s a memory you want to last indefinitely. It’s a subject many people don’t touch on when they examine a film like Blade Runner (1982), but director Ridley Scott’s film does place an emphasis on the importance of photographs and what they can mean to people. The film depicts photos as a gateway to nostalgia, the immortalization of important figures and how photographs can deceive their owners. When you hold onto a photography they are generally a preserved version of a past memory that is important or a time of happiness.
These photographers and filmmakers are significant for the blending of science and art that criticized culture and ideology. As we shall see later in this book, photos (and media) with a purpose live on and documentarians continue to emulate many of these stylistic techniques practicing the science of ecology of the
A photograph is more than just a simple image; it tells a story. A story beyond a particular moment in time, it holds secrets and memories. The eagerness to comprise a moment in the perfect shot seems to become an obsession for many. In Kim Edwards ' novel The Memory Keeper 's Daughter, Edwards uses photography as a motif which coincides with the novel 's idea of secrets. David Henry, the antagonist of the novel, becomes fascinated with photography after choosing to give away his daughter and compresses his guilt with photography.
For example, unintended explosions can be minimized by placing the storage containers away from electrical connections and appliances. Instead of using wooden structures, metal hoppers and concrete bins may serve as safer substitutes for the storage of FGAN. In essence, the materials should be transported safely by eliminating the principal obvious sources of fuel such as combustible materials that may spark an explosion. Given that FGAN is a strong oxidant, untreated wood should never be used to fabricate storage structures for FGAN since it may accelerate the magnitude of detonation (CSB, 2016 p.104).
"The photographic image is the object itself, the object freed from the conditions of time and space that govern it. No matter how fuzzy, distorted, or discolored, no matter how lacking, in documentary value the image may be, it shares, by virtue of the very process of its be- coming, the being of the model of which it is the reproduction; it is the model." "Photography does not create eternity, as art does, it embalms time, rescuing it simply from its proper corruption. The aesthetic qualities of photography are to be sought in its power to lay bare the realities."
Not only does the dress and movie scene live on, but the photos hold a timeless immortality that people will be able to recognize for years to
