Oil painting on linen canvas – I use a linen canvas with a white covering for certain types of painting such as landscapes set in Wales as there is a particular type of “Welsh light” that can be captured accurately on this type of canvas. It is extraordinary how a canvas is so conducive to a certain “national light” but all light is different depending on where one is located in the world. My husband hails for the north of Ireland where the light is brighter and more shrill, high pitched, more crisply blue white, whereas in Wales, it is often slightly or noticeably softer and in certain places tinged with warmer yellowy white. Although in this painting which is heading towards West Wales, and towards the Irish Sea the light has become more crisp and slightly tinged with blue. One can almost feel the lung filling fresh air in the blowing clouds and nasal tinging blue sky.
