As a painter, I'm very much aware of 'the fleetness of the moment'. A moment in Summer, a moment in the day, a moment of bright colors, these things.
As a plein air painter perhaps more specific, you can feel it fleeting by. Anyway, sometimes the beauty is so glorious, it's then so clear. Luckily we can paint it. Savouring the moment in paint.
