restoration of digitised paintings


Digital restoration is an option often pursued for delicate and damaged sentimental photographs and documents so that they may be handled and put on display. The Center digitally reproduces pieces on archival paper with archival ink, and can provide a wide range of digital storage options.

Restoration of images is achieved by using various brushes and tools, including the Spot Healing Brush , Clone Stamp Tool , and Healing Brush
