Thank you for sharing this superb find Duncan. Both the quality and content of these restored plates is truly amazing. I have heard of early music performances on record being restored almost note by note by a keen digitalist; this does the same for the photos. However the name of Prokudin-Gorskii deserves to be better known as a genius of photography as the basic content must have been there from the start. When one looks out those ghastly 70s colour prints and tries to get a decent pic back out....

Also just the job for rainy days when WPF isn't coming up with its normal standard, can he be made an honorary member? I am sure you could post some with current date and no-one would guess the exif data. 00458 could easily be taken at a railway museum yesterday.
