Treasure of the Seirra Madre', etc. DVD art...

...if you thought those were cool, check out the box set for all three and the graphical explanation of how the transfer for "Adventures of Robin Hood" was achieved from the Technicolor separations. These were posted by Ron Epstein over at the Home Theater Forum:

It is the same proprietary WB process as was used for "Singin' in the Rain".

The big problem with using B&W separation masters vs. color negative to create images is usually "differential shrinkage" (and, no, Mr. and/or Ms. Smarty-pants, that was not the subject of a Seinfeld episode). The B&W negative does not fade with time, but it can change slightly in size. The WB process digitally recombines the separation masters frame by frame and adjusts the geometry to correct for size variations that could cause small to large errors in registration. Small registration errors result in "fringing" or blurred edges. An example of a video transfer from an element with gross registration problems would be either of the DVD releases of "The Quiet Man".
