A recent conversation with a fellow photographer made me think about this. He was talking about another artists he knows and how his images had stark contrast while he was going through personal turmoil. And then one day all the new work was airy and brighter. Which made him guess that his friend has found love again.
Not sure of such a distinct relationship between the art and the artist however it is possible. Here is an image from bolehill in peak district. Version 1 is right after few days of making this image whereas version 2 a recent one. I was intentionally started listening to a certain kind of music while processing images. What do you think?
