Query: Possibly the worst instructional DVD I have ever seen

A ponderous presentation by an artist with a blinkered view of technique. The cameraman failed to zoom in on the painting as it progressed. The spectator had to peer from a distance. The artists back was clearer than his picture. The colour resolution was awful, everything looked grey, even the brightest red. To cap it all it didn't offer one new technique. This artist actually deliberately avoided some the opportunities that came his way. He didn't like bloom, yet didn't admit it was all a matter of taste. It should have been called how to paint, with a stiff arm and no brush, that was its only unique selling point.
