I have some Ansco Color slides from the mid-1940s, and their color has become
wonderously bizarre. However, they are of important family events and are still
highly valued.

We owe a big debt of gratitude to Ed Hamrick for the "faded color" correction
capabilities in VueScan. The results on the Ansco slides is still pretty aweful,
but so much better than without the corrections!
