【實用攝影app】Camera - Sepia|最夯免費app-綠色工廠好玩App

Sepia toning is a specialized treatment to give a black-and-white photographic print a warmer tone and to enhance its archival qualities. Chemicals are used to convert the metallic silver in the print to a sulfide compound, which is much more resistant to the effects of environmental pollutants such as atmospheric sulfur compounds. Silver sulfide is at least 50% more stable than silver. Preserve your photos and give them a warmer tone on Windows Phone.
