The one that did it

Just this year I browsed through an essay at AKV St. Joost in Breda at their Photography department. And I saw the uncredited picture questioning the date on it. After a small bit of research someone told me it was made in the beginning of the previous century. Which was totally new to me. Why doesn't that coop with the historical timetable based on cognitive herital memory. Of course that leaves me towards giving some examples of the obvious dates:


1825: Heliograph - Niépce


1826: Le Gras - Niépce


1836: Photogram - Fox Talbot


1838: Boulevard du Temple - Daguerre

And then there was this picture:


Made in 1907 by Prokudin-Gorsky

In that same era b/w picture were still made:
