The Camera Obscura Hockney’s thesis
.Around 1430, painters began employing a concave mirror to project brightly-lit subjects onto a canvas, thus allowing them to render subjects with unprecedented naturalism
.Towards the end of the sixteenth century, painters began to use refractive lenses instead of concave mirrors to project their images, producing images in which left and right were reversed.
History of the camera obscura
4th century BCE: Aristotle -- during solar eclipse, circles of light on ground beneath a plane tree turn to thin crescents
10th century: Ibn-al-Haitham: images of sun could be projected onto wall of room
1550: Cardano -- addition of lens in aperture (Hockney “late” device)
1558: Della Porta, concave mirror camera obscura (Hockney “early” device)
1585: Benedetti: Lens and oblique plane mirror
1589: Della Porta, revised edition, concave mirror with convex lens
