How do you know when your paintings are finished? A Quote by Gerhard Richter matthiasott.com When nothing disturbs me and I have no idea what to do more, what I could add or destroy. This is very surprising, often, when I’m painting, again and again, every day and it feels like it is never-ending […] and it will never become a good painting. And suddenly, it’s finished. Oh! Good. Thanks. Painting With the Web perfectionprogressending
Caustic (optics) Caustics made by the surface of water. In optics, a caustic is the envelope of light rays reflected or refracted by a curved surface or object, or the projection of that envelope of rays on another surface. The caustic is a curve or surface to which each of the light rays is tangent, defining a boundary of an envelope of rays as a curve of concentrated light.
