After watching The Repair Shop on BBC1 restore a beautiful and rather rare ferrotype camera I thought a blog on the process would be interesting. Not only did they repair but they managed to have the camera working, taking photographs. This was very inspirational given the age of the camera. ABOUT FERROTYPE PROCESS Ferrotypes first appeared in America in the 1850s, but didn’t become popular in Britain until the 1870s. They were still being made by while-you-wait street photographers as late as the 1950s. The ferrotype process was a variation of the collodion positive, and used a similar process to  wet plate photography . A very underexposed negative image was produced on a thin iron plate. It was blackened by painting, lacquering or enamelling, and coated with a collodion photographic emulsion. The dark background gave the resulting image the appearance of a positive.

One of our most interesting orders came in today in the form of a vellum property deed dating back nearly 200 years. We were asked to prepare a digital copy so our client could preserve the original. After assessment we decided on which scanner to use and scanned the deed to a high quality Archival TIFF file before applying post production tone and sharpening.

This meant the original's replica could be matched 100% to the original, safeguarding fraud. What is vellum?
