Brief Explanations:

Jan van Eyck was a key figure in the Northern Renaissance. He is renowned for his contributions to painting techniques. He developed oil - painting techniques which allowed for greater realism in art. This included details in textures, light, and shadow. Watercolors were not his main medium. Stylistic techniques (which are more about a particular style rather than realism) do not fully capture his contribution. His works, such as The Arnolfini Portrait, showcase the realistic details made possible by his techniques.
