David Hockney's iphone dawn

"I've always wanted to be able to paint the dawn. After all, what clearer, more luminous light are we ever afforded? Especially here where the light comes rising over the sea, just the opposite of my old California haunts. But in the old days one never could, because, of course, ordinarily it would be too dark to see the paints; or else, if you turned on a light so as to be able to see them, you'd lose the subtle gathering tones of the coming sun. But with an iPhone, I don't even have to get out of bed, I just reach for the device, turn it on, start mixing and matching the colors, laying in the evolving scene." — David Hockney, NYRB
