Saw this BBC documentary a long time ago in 2011 and I found it again by accident today in 2020. This documentary made me appreciate just how brilliant David Hockney is.
Ever since I saw this type of painting in my youth, my mother always included a sojourn at the National Gallery when we went up to London by tube, I was fascinated by the problem of how the artists did it. The intricate lacework on the ruffs seemed impossible to achieve.
It never occurred to me when I was nine it was traced as today we trace in Adobe Illustrator. Hockney's explanation is so simple and his evidence conclusive.
All these pictures are about 32 cm square as that is the size that the subject comes into focus. When shown in black and white they all look like photos. This all happened about 1420. Yes, it can be dated.
