This technique is very much a mix of different paint applications, not the traditional oil painting method. Over the years I’ve painted in watercolours and pastels. This time for a change from my normal method I used some watercolour and pastel handling methods. Of course its not exactly the same, and not something I would do on a longterm basis.
There are thin liquid washes of White Spirits with fine details painted over the ‘dry’ washes as in watercolour. Because of the medium in the oil paint, the washes are not fully dry as in watercolour, nevertheless, the effect is similar.
Also used is an application of paint similar to pastel. The colour is applied flat using the texture of the canvas to remove the paint from the brush. Sap Green is applied in this manner on the trees. Pastel colours are not mixed, each colour and shade are a separate paint stick, which is drawn directly on the textured paper. So it was with this green. Again, because the under-colour was still not fully dry there was a certain amount of mixing.
Sap Green is one of the few green colours that can be used in this way. Its very transparent, for this reason its dark in tone in the thick layers and lighter when the layer is thin. So when the wide brush containing pure Sap Green is dragged over the surface of the painting a range of green tones are produced. Add to this the mixing with the wet under-painting and an infinite variety of colours are produced.
The ‘painting’ of the moon was actually paint removed with a fine brush moistened with spirits. The circular shape was pressed onto the canvas using a strip of waste canvas rolled into a cylinder. I roll the piece into a cylinder until the diameter is what I need. A compass would seem to be the best way of doing this but the solid piece of canvas can be felt and the diameter seen as a solid circle. Its difficult to draw a perfect circle so this is my quick way of getting a circle at the correct size.
