Not everyone agrees with Hockney’s thesis. Some counter arguments, here and here. The later one is perhaps the most valid because its author is a scholar. Hockney’s project has inspired further exploration and scholarship.
Abelardo Morell, Camera Obscura: Early Morning View of the East Side of Midtown Manhattan, 2014
Just some inspiration for your What is Photography? assignment. This image is by Abelardo Morell. He creates custom camera obscura, often turning an entire room into a camera, and then photographs the camera-less image. So what you’re looking at is a photograph of an image produced by a camera obscura. Got it?
The image is from Morell’s upcoming exhibition at Edwynn Houk Gallery in New York.
