During sepia toning, silver is replaced by silver sulfide, which less prone deterioration. Silver sulfide is brownish in color, which gives the photographs their characteristic brown or sepia tone. This chemical replacement not only changes the color of the photograph but also increases its resistance to environmental factors like air, moisture, and light exposure.

Even for photos that were not originally sepia-toned, aging oxidation processes cause black–white photos develop a brown tint over time. In older photos, exposure to air, light, and humidity can lead to the gradual oxidation of the silver particles.
