We sketched at Canary Spring in September when I visited with my Yellowstone Institute class; in previous posts I have featured students' work. This is what I came up with and I was happy with the ethereal quality of it--for me this is what watercolor can do like no other medium. I think John Henry Twachtman's oil paintings of the pools are marvelous, but few other oil paintings have done them justice. I've been re-reading John Berger, whose thinking on art was so seminal in the 70s. In Ways of Seeing he talks about the contrast between oil painting and watercolor: What distinguishes oil painting from any other form of painting is its special ability ro render the tangibility, the texture, the lustre, the solidity of what it depicts. It defines the real as that which you can put your hands on. It is interesting to note here the exceptional case of William Blake. As a draughtsman and engraver Blake learned according to the rules of the tradition. But when he came to make paintings, he very seldom used oil paint, and although he still relied upon the traditional conventions of drawing, he did everything he could to make his figures lose substance, to become transparent and indeterminate one from the other, to defy gravity, to be present but intangible, to glow without a definable surface, not to be reducible to objects. This wish of Blake's to transcend the 'substantiality' of oil paint derived from a deep insight into the meaning and limitations of this tradition. Blake found watercolor more appropriate for his purposes, and it's that vaporous quality that I love so much. It captures the fleeting moment and experiences that pass away before we can even really register them, before they solidify into memories.
