This is one of my favourite shots. It was taken back in 2014 on an October morning. The sun was spilling through the trees and creating the wonderful golden colour. I rotated the camera to capture the various tones of colour and contrast and a line formed where I stopped. It looks like a you are looking down on a cone to me, hence the name but others also see a tunnel. I think of these rotational shots as a like a “light lathe” where the scene is cutting many concentric circles into the image.
