A wooded glen becomes a dazzling fireworks display of streaming golden light and confetti-like showers of leaves in Gary Collins’ “Aspen Glow.” Adeptly capturing the feeling of the setting as well as its appearance, Collins strives to reproduce the pleasure of a fleeting moment of color and light by preserving it in his work. Collins, a contemporary oil and watercolor landscape painter with a lifelong fascination of nature and the aspen tree, travels throughout the world, painting outdoors during the summer in France and Italy.
