David Hockney RA: A Bigger Picture - VI

One of the study painting of Hockney's - "The Sermon On The Mount", a sketch from the painting.
The top part is a reseach piece from his notes.
He recently painted a version of Claude Lorrain’s “The Sermon on the Mount” (1656), and he is”restoring” the painting, digitally stripping the grime and dust from a photograph of the Frick Collection original.
