I've been going the archives of what I call my macro photographs.
The picture below was made about the same time (circa 2019) as the images on this post on Thoughtfactory's photo blog and with the same macro camera equipment. It was the colours of the quartz that initially caught my eye. Then I saw the seaweed strand lying across the quartz vein.
I thought that this moment wouldn't last very long, as the coastal wind would quickly move the shape and the line of the seaweed strand, then eventually blow it off the quartz. So I quickly made a photo.
I was on a poodlewalk at the time, and I was looking for some dried salt ponds among the granite rocks to photograph. We would have been walking in the late afternoon.
