I think the comparisson between Ingres’ beautiful portrait drawings and Hockney’s attempts using optical aids speak for itself… (see attachments)
Also, when asked why Hockney only demonstrated drawing and not a completed painting, he replied that he had tried painting with his camera obscura, but had abandoned the effort “within ten minutes” because it was far too impractical. So what is he saying here? The masters needed optical devices but it is far too difficult for himself to create something worthwhile with it?
