Take a look at these wunderful images in the article. Read the texts and you understand that this is no ordinary b/w prints that are tinted. Amazing work! I read this in The Guardian.
Text for the above image.
Lauterbrunnen and the Staubbach waterfall, Switzerland. Circa 1900
Creating a photochrome involved taking detailed notes on the colours present in the photographed scene, and then hand-colouring the negative
Remember that photographers had to use b/w or color film years ago. Or just b/w if it was many years ago. Today it is easier with everything built into a camera.
The Rhine Falls, Switzerland. Circa 1890
The image on the negative meant that different amounts of light fell on different areas of the coating, which then hardened according to the amount of light to which it had been exposed
Finally: Now I have seen the question, again. Is photography art? In my opinion YES it could be, but not every photograph is. Far from!
