People who are new to framing often have many questions about how to frame their photography in a way that will help prevent yellowing and fading. The Image Permanence Institute (IPI), a leader in the development of practices for the preservation of images, has some great information about archival framing. With their permission, we have taken one of their extensive articles and published it on our website at: A Consumer Guide to Materials for Preservation Framing and the Display of Photographic Images.
This is a very comprehensive article. It starts with an introduction to the various components of the picture frame package, which makes it a great introduction to framing. It then moves into the types of decay that cause degradation of photos, discusses best practices and offers has tips the on proper display of framed photography.
