Photographs of 19th Century Japan

It looks like the other blog post linked to about the photos of the Russian Empire is behind a paywall, but the original Prokudin-Gorskii collection is available for free at the Library of Congress: https://www.loc.gov/collections/prokudin-gorskii/about-this-...

Unlike these photographs from Japan, the ones from the Russian Empire were made with colored photographic plates and they were reassembled into true color photos and restored in the last few decades.

Sadly the photos from the Monsen American west collection seem to be guarded closely by Princeton and are not viewable to the public without requesting physical access. https://findingaids.princeton.edu/catalog/C1539

Edit: Looks like much of the Monsen Ethnographic Indian Photographs Portfolio can be found in the Huntington digital library: https://hdl.huntington.org/digital/collection/p15150coll2/se... - content warning!
