Interesting piece of film from 1928 of the artist Phillip Alexius de Laszlo painting a portrait. He seems to be working sight sized although if he is I’m suprised not to see him stepping back much further from the canvas to better judge the relationships between his canvas and the model, something I’d always associated with this way of working. Was he having to adapt his way of working to the demands of being filmed, one wonders?
I know very little about this artist beyond the fact that he took over John Singer Sargent’s portrait practise after he died but if you want to find out more you could start here.
