Of course you can still paint landscape - it's not been worn out.
Teaching people to draw is teaching people to look
Every good artist I know, I always think works hard, we're working all the time.
About shadows: do we see shadows? Loads of people don't. A camera will notice a shadow, but how many people have got a shadow in front of them when they take a picture and don't notice it, and then they see it in the photograph because the photograph will catch the shadow.
Always live in the ugliest house on the street - then you don't have to look at it.
I was aware that the teaching of drawing was being stopped almost 30 years ago. And I always said, 'The teaching of drawing is the teaching of looking.' A lot of people don't look very hard.
