Huh. I thought I had the whole collection, and while I have a lot of pictures that aren’t shown here, a good chunk of those they’re showing I don’t have. I guess they’ve colorized more of the archive since I downloaded it from the LOC.
It’s a lot easier to convert the images to color today than it used to be, thanks to computers. ;)
Those aren’t color converted photos. They’re the real deal. Color photography was being experimented with in the mid 19th century. Made it out of the lab and into the hands of photographers (who could afford it) around the turn of the 20th.
