While some photographers at the beginning of the photographic age tried to mimic the visual aesthetics of painting to establish their “technical images” as another art form, it’s interesting to see how photography had an impact on painting. The technique of painting with the help of tools like the camera obscura or different ways of using projections has been established before the first daguerreotype was created. But photography could be seen as the perfection of these kind of helping tools.
There is an interesting blog post which lists several examples of paintings by Gaugin, Cezanne, van Gogh, Lautrec & Degas which have been produced with the help of a photographical template. See for yourself:
