Iâ€™ve been reading a book this week called Mastering Glazing Techniques in Watercolor (Rankin) which has been affecting my thinking about other kinds of painting. Perhaps youâ€™ve seen a watercolor painting in which the colors seemed to glow from within, or one that had an ethereal feeling to it. How do they do that? The author says that effect can be achieved by using thin layers of transparent color over white paper and using glazes in the right order and of the right value. The author is particularly fond of glazing with Winsor Blue, Winsor red and aureolin yellow (or new gamboge.) Although watercolor painting and digital painting use completely different processes to achieve different hues (one subtractive, with pigment and one additive, with light) I thought it would be interesting to try â€˜glazingâ€™ in Photoshop by building up the color on multiple layers. This was just a quick experimental sketch on a piece of scrap paper, scanned and then painted, to see how it would work.
