In this part of the blog I will explain in detail the decisions I take, the techniques, the colors and type of brushes I use to make the paintings from the very beginning so that if you decide to start painting on your own, you can use this as a guide. Painting astronomical objects in oil on canvas is not easy. This is the reason why most artists create digital images instead. Even though it is not an easy task and probably my paintings will not be as perfect as if I created digitized work, I decided to do this collection in oils because the brushstrokes show the imperfections, I might say, the humanity, of the person holding the brush and because I simply adore oils. Contrary to a print, an original oil painting is a unique work of art that has texture you can see and feel.
Stage 1. For this painting, I started out with a white cotton canvas which I primed four times with black gesso, a mixture consisting of a binder mixed with chalk, gypsum and black pigment. I coated the canvas with thin brushstrokes because I don’t want the structure of the canvas itself to disappear. After each coat, I sanded the canvas delicately with the finest sand paper, to get rid of unwanted brushstrokes. After the fourth coat, the canvas was let to dry completely overnight. To serve as a guide, I made a light pastel chalk drawing of the object.
Stage 2. For this stage I used viridian green. I mixed it with cadmium yellow for bright green and with pthalo blue for turquoise shade. I used titanium white mixed with cadmium yellow for the highlights.
Stage 3. I continued blending the center of the nebula with the colors mixed in stage 2. I also prepared a mixture of cadmium red and cadmium yellow for the orange tint.
