I have long been familiar with a Henry Taunt image of the road from Long to Little Wittenham but in a recent web search found an interesting twist on the theme.
The two images below clearly show that Taunt like other commercial photographers used ‘combination printing‘ in dropping in a separate cloud background.
I was familiar with Gustave Le Gray’s use of this technique in seascapes.

Here the two images. The second image is I presume the original.
Without inspecting the originals in the Oxford Museum collection
which may take some time as there 14000 images I cannot say if my hunch correct yet.
Here a pdf of the catalogue
Here more images from the visit of Taunt and his camera to the village in 1890?
There is a fine website dedicated to a Taunt revisited photography project here:
This is what I call a floating tripod..
