How can I care for photographs?
Photographs are delicate, chemically created objects that are very sensitive to environmental conditions, in particular light, humidity, and heat. They should be stored somewhere with a stable temperature (between 10 to 18º C is ideal) and relative humidity (35 to 50% is best, but 40 to 60% is often accepted).
When displaying your photographs, try to use low artificial lighting rather than direct sunlight, which will cause the image to fade rapidly.
Hold the photographs and negatives by their edges when handling them and be careful not to touch the surface. The dirt and oil from fingertips can cause long-term damage, so wear clean cotton or nitrile gloves when you can.
If you want to label the back of a photograph, use a soft 2B pencil instead of pen ink, which can seep into the image, and place the label on the edge of the photograph (away from the image). If you are numbering the enclosure, write the number before you put the photograph or negative into it. It’s always best to store photographs in Mylar sleeves or acid-free paper. Negatives should be kept in acid-free paper enclosures.
If you have digital copies of your photographs, make sure to have back-up copies as well. We recommend keeping them on an external hard drive or good quality archival CDs. Be aware that CDs can deteriorate over time, so store them in a cool dry place and check them regularly to see they are still working.
