Recovery of Images [9:49 am]
This is partly off-topic, in that the focus of the article is on the technology applied to recovering pictures of the Kennedys from contact sheets after the negatives had been lost: Retrieving a Rare Glimpse of Those Fabled 1,000 Days.
But, consider the implications if digital rights management instruments were built into these scanners (or, the PhotoShop used to recover the materials). The creator is dead, but the copyright has not expired. Luckily, in this case, the owner of the copyright could be found. But, without that discovery, in a world of watermark-recognizing digital devices, the recovery of the information in the contact sheets would be vastly more expensive, due to the need for customized (and potentially illegal) equipment & software and the liability insurance that almost any publisher would want for undertaking the project at all.
