Scott,
It is my understanding that the reason they purposefully leave the lights set the way you saw is to help make the prints last longer. All those photographers you mentioned are long dead and there will be no more images. So, one of the accepted ways to help preserve the longevity of the prints is not to have bright lights shining on them. It is a sad but necessary fact if we want the prints to be around for our later generations.
