TV is always a good source of faces to sketch, press pause and they’ll happily pose for as long as you need; I like the way the drawings tend towards caricature. There’s sometimes a bit of lens/screen distortion on archive clips, and I think the trick is to work fairly fast. It doesn’t have the satisfaction of translating the 3D world into 2D, but it’s great for spotting the key lines and tones on a face, and rendering them accurately. So here’s a leonine BBC history presenter enthusing about castles, an all-round entertainer smoking and singing, a top international chef with a fine forehead, and an extravagantly coiffured late 1960’s singer/songwriter. Happy Christmas TV viewing!
