Often the result of improper storage, silver mirroring affects many old photographs and prints. Silver mirroring is a light blue, reflective sheen that manifests in the darkest shadows of a photograph. It may be localized and relatively unobtrusive or, as in this example, completely ruin the dark tones of an image. With such photos, we selectively darken only those areas affected by the mirroring. It’s a painstaking process, but the result is worth the effort.
