These Ice crystal formed under the right conditions. Moisture and the right temperature created incredible works of natural art!They had formed on the exterior of a few of my windows, and I photographed them with a macro lens fitted with a 1.4x converter to increase magnification from the interior and warmth of my house! As with all my images, they were created in the camera with my imagination and creativity and full control with no post production tools. Natural light at different times of the day created different color temperatures for the right mood. You will note, some of the crystal caught the sun, and created a prism effect, which reflected colors of the rainbow.
