Spacers built into the bindings keep the album from fanning at the outer edge. Attach photographs only at the comers. A variety of comer tabs are available so that the photo does not have to be glued down. Glass with an ultraviolet filter will protect the photograph from sunlight as well as dirt and dust. Plastic or unfinished wood frames may leak acidic gasses.
Wood frames can also absorb water and attract small bugs.
Metal frames avoid these problems. Acid free board, or museum board should be used for all matting. Restoration Re-photographing is a popular method of restoration. Color filters can be added to restore some of the color. But each time a piece is rephotographed some of the detail in the original is lost.
