My value studies were made with Walnut ink which I made from the walnuts in my yard. See my post on making walnut ink. Also, the dark values were possible by adding Tom Norton’s walnut darkening medium.
Syd is an oil painting from a couple sessions at the Atwood Atelier in Madison, Wisconsin.
Brushesandpigments.com, Explorations in OIl Painting.com, Huesandvalues.com, and Valueandhues.org are websites all concerned with art and especially oil painting. Valueandhues.org is the present, online website where I write about color and art and also show some of my paintings occasionally. My blog is on a monthly schedule.
