PMG Environmental Standards and Guidelines for Storage
|Date initiated||September 2009|
|Contributors||Luisa Casella, Stephanie Watkins|
Purpose of Environmental and Storage Guidelines[edit | edit source]
- Identify the variety of complex and interwoven forces that effect change, and thus, the preservation of photographic materials.
- Utilize the most recent information to maximize the chemical and physical stability of all photographic materials while in storage.
- Minimize changes in the image, binder, and support from agents of change, such as light exposure, temperature (heat, freeze-thaw cycles, cool storage, cold storage), humidity, pollution, storage container or collection material off-gassing, or any other environmental or storage related factors.

Standards, Guidelines and Recommendations[edit | edit source]
Cool and Cold Storage[edit | edit source]
- Art Institute of Chicago (IL, USA):
- Amon Carter Museum of American Art (TX, USA): Cool is 60°F, 40% RH, Cold is 20°F, 30% RH, and a vestibule for acclimatizing photographs between the two is 40°F, 35% RH (all temperatures ±3°F) (Panadero, 2019).
- Harry Ransom Humanities Research Center, University of Texas at Austin (TX, USA) (nitrate and acetate film vault):
- Indiana Historical Society (IL, USA): Temperature and RH set points are 50°F and 35% RH.
- Museum of Fine Arts, Houston (TX, USA):
- NARA (National Archives and Records Administration) (MD, USA):
