When walking in the Upper Mariposa Grove back in October, we saw deer grazing beneath a giant sequoia, and it gave us a very immediate sense of the enormous scale of the the tree. This week I used my photograph, some walnut ink loaded into Niji waterbrushes, and a Pitt sepia brush pen to sketch the scene. I buy walnut ink crystals at John Neal Books, and mix them with distilled water. This way you can determine the degree of saturation--I find the bottles of walnut ink available at art stores are too diluted for my purposes. I wet the tree area first, and then brushed in the walnut ink, using 2 different saturations, loaded into 2 different Niji waterbrushes. After the wash dried, I used the Pitt sepia pen to stroke in a few quick dark lines. I've written about walnut ink several times in these pages, as it's my favorite sketching medium, and I'm pleased that a few of my sketches will appear in the upcoming book Sketchbook Confidential 2, published by North Light Books, and available this May.
