This stunningly detailed photograph was taken on Saturday 11th September 1869 and shows the construction of the Holborn Viaduct. So much magic to zoom into and see in this picture. I particularly love the advertisements.

Maybe a silly question, but how do you colorize? I mean, how do you know that the colour or shading chosen is also the colour that was there in reality?

The ai model learns a whole mix of recognizing what objects are (and therefore what color they should be), as well as deriving likely colors based on other characteristics and some context in the photos.
