This time I had to go back to my archive, as the shots I took in the morning, didn’t work.
Starting off with a single helix, shaped from an off-cut sliver of metal. Then sanding the edges to get the fine lines. It needed some experimentation with a vibrating motion -50 Hz- and using filtered lighting. The dark background was ideal to create a mirror image in Photoshop. A lot of work, but rewarding. Thomas
