Katherine, how generous of you!
I must say that when I first looked at this image I thought about molten steel that had cooled when in fact it is of something that is quite the opposite. Reminiscent of your own pumpkin slices. "Art" may appear in peculiar and unexpected places.
Fascinating. I used to take (oops I nearly said what it is)pictures in B & W but nothing like that.
Thank you for the mention Katherine :) ...and the compliments. Writing and photography are my favourite hobbies, I wish I had more time for them!
