Sometimes after a sustained session of painting I go out for a walk in the country and a strange thing happens. The trees or flowers seem to stand out in intricate detail, like I have special vision or something. It’s amazing. It doesn’t happen always but often it does. I think it must have something to do with the level of concentration and perceptual changes you experience while painting or drawing and it just carries on for a while after. It happened yesterday after painting when I went outside, it goes away eventually, sadly. I wonder if any other artists experience this too?
