Nancy Worth is a Colorado based artist who has been artist-in-residence at Rocky Mountain National Park and still leads an annual workshop there, as well as teaching in other capacities, including classes at the Cottonwoods Artists School. She attended Trinity University in San Antonio, Texas.
Despite her southwest and mountain state surroundings, the most appealing of her paintings that I have seen on the web are of Paris, particularly her paintings of the sun dappled quays of the Seine River.
Worth worked in oil originally and then moved to transparent watercolor, to which she devoted herself for a number of years.
She has recently returned to to oil painting, bringing with her the years of watercolor technique, and her oils have a fascinating quality of feeling a bit like both mediums, with some of the airy lightness of transparent watercolor next to the rough painterly textures possible only in oil.
