This is frozen water on a window photographed against the morning sun. This is a scan from a slide. I photographed this image as a teenager with my first SLR, a Minolta XE5. By the way, I still have the camera and I still use the lenses with a connector to my modern cameras. I believe I used the 50mm Minolta 1.4 prime lens to create this picture.
Enjoy and keep on photographing!
